FEED ME! Fuel Pump Wiring Upgrade w/ Hangar Mod ALL Modified Fox Body Mustangs 

Neo, this video saved me. Just installed a 340lph pump and have the upgraded wiring kit but was a bit lost on how to wire it in without replacing the top hat. If all I have to do is modify the top hat, I’m happy. Thanks.

I still really like these older informational format videos! I’m about to do the Aeromotive 340lph pump on my 92 GT this weekend. Thank you for the video!

What pump is that part # all the aeromotive pumps are pre wired with 16 gauge wire. No way to wire it up like you did. Plz help lol.

I'm super grateful for this video Neo! This resolved my fuel pressure drop I was having with anything over 8PSI on my Turbo 347 with a walbro 400. Fuel Pressure would drop into low 40s before and after the upgrade I'm sitting at a solid 55PSI at 11# of boost.

Excellent informative video! Thanks for taking the time to make these videos for the fox crowd it's appreciated by myself and so many...

This is like Christmas morning to me I'm all smiles been waiting for this video but was not worried because I know Neo got us covered

Great video man very nice upgrade..

Man you always come through in the mic of time to walk me through my build. Thank you!

Thanks man! Perfect solution for my fuel pump upgrade!

I did this and it works. I modified mine so I didnt have to drill. But this vid rocks

Great video. Love all the average joe tech you post it really helps with a budget build like mine making every penny count. Keep me coming

Talk about good timing to watch this video. Just installed my turbo and got my 340 fuel pump in the mail. Now I got to go get some 10 guage wire. Thanks for this video. I know it's an old one but it still good information. 👍

Great video, thanks for sharing.

Great video, thanks

Love the content! Keep it coming

Excellent video you know your stuff!!I will be doing that to my 87 best video on RU-vid explaining that keep up the good work man!!

Awesome content... great info....

Great video thank you for posting!!

Is not to long Dan , great video, so much information appreciate 👍🇵🇷

Man that blue with those black wheels makes that car look good!

Thanks for posting the video. I just installed a turbo on my foxbody. Above 4K getting into boost the car goes super lean. Today I did this wire mod on my walbro 255. Tomorrow I’ll test it and see if it solves my problem.

great video I am in the middle of upgrading to a 380lph inline pump

Awesome video I've been in the game for years get rid of that m s d junk

on amazon get "5 pack 12" 10 Gauge 2 Pin Quick Disconnect Audiopipe Polarized Wire Harness" Nice set up thanks for the vids.

Nice foxbody live that ride 💪😎power go ford #1

I'm losing voltage from my relay to the pump. I remembered seeing this video. I think this mod would fix my problem and probably need it to feed my 340 pump anyways

Gracias por El video tenia problemas con El sobre calietamiento de relay de la fuel pump q esta debajo de mi aciento ya q mi fox body es del 1991.monte una walbro 255 lph.

Awesome, thank you. I just installed a Walbro 255. Looks like the fuel pump wiring is a future mod. I was just wondering why not drill the stock stuff out when you decided to do that. On connectors - I used the heat shrink connectors.

Thank you for the video just did the mod. 2 quick questions. The air line that normally goes from throttle body to filler tube do you block it off?? And do you have a video on modifying driver valve cover for breather?? Happy Easter to you and your family!!! Thanks again!!

Hey I have a question.. my return line got stuck the way yours did and I got it apart but unfortunately the plastic retainers came out with it..is the line still reusable if I get a new retainer and reassemble the inside of the connection..the line is in excellent shape otherwise and it would suck to have to buy a new one..thanks in advance

Brother, If your video is 3 hours long, with the infor you're given, I'd watch it. Thank you, sir.

What is the part number for the pump ? Bought the Aeromotive pump and heavy wiring kit and the pump is pre wired with 16 gauge wires lol does not have the male to female connections for the wires to run 10 gauge wires.

Great video! I’m in the process of hard wiring my fuel pump on my supercharged mustang. Is the 340 pump to big for the stock fuel lines? Thanks

I’m actually having some fuel issues now. I’m running a stock tank with a sump in my 85 347 carb setup using a holley blue dead headed. Pump is on the steel bumper about an inch above the sump. All of a sudden about 1k miles later the pump won’t prime with less than about 4-5 gallons In the tank Basically I have to run a half tank of gas minimum. -About a foot of10an to the filter and pump then -8an to the front. I’m debating using a fuel injection tank and figuring out how to regulate it down to 6.5 psi for the carb. Or a fuel cell In the spare tire well ?? I changed the pump cleaned the filters and it’s all new stainless fuel line. Any ideas or help would be great.

do you not extend your return line to prevent aeration so the pump isn't pulling air along with fuel?

Hey I have question for you i am going to build a fox body as well, i have a 360 FE sitting in my garage right now. What type of wire were you using for the fuel pump? Can that be submerged in gasoline for extended period of time? Oh hail from Ohio lol

Damn i just installed this pump in my 93 notch yesterday. I installed the terminator x in February and i have the pump drive wire from under the passenger seat ran 10gauge into the trunk to the realy. The battery is in the trunk also. I wanted to run the 10 gauge from the pump out of the tank and didnt even think to pull off the factory connector peice...looks like im dropping the tank again lol thanks for the information!!!

They sell those aeromotive pumps today hardwired and you can't change the wires and they look thinner is that a problem especially to fuse it at 30A if that wiring on the pump looks like 16awg

so no wires go to the ecu, its just wired in direct to the battery and relay and then to the pink and black wire to signal on the pump????

I have a two question hopefully you can help me out. I wired my 90 fox like you did in the video but when I key on the car I get nothing from the pump. I can hook 12v right to it and it pumps. Is the pink w/black stripe the trigger right. Also if I'm installing holly terminator do I not mess with there green fuel wire and just stay how you did this car. Thanks. Sorry for long comment.

What's up Neo. Have a question man! Do you know what can cause fuel pressure drop at wot after car has been driven for an hr or so. First 30min of drive car is fine at wot. New fuel lines 8 feed and 6 return. Second new pump 525 holley. New fuel regulator. 80# injectors. Fuel relay kit straight to pump. Voltage at wot at pump is 13.4... fuel filter is hot to the touch and it's not near any heat. Scratching my head on this one.

"Lph" liquid per hour ... Lol ... Liters per hour ... Good show

If I just vent my tank like you did, I don't need that vaper canister under the hood right?

Neo what if the 340 Aeromotive pump itself has its own wire coming out of it ? I’m assuming I purchased the newer style . Thats where I’m stuck at right now . :(

Do you use any specific wire safe for submerging in fuel and without termination at the hanger hat is there a chance of fuel wicking up the wire I am planning to upgrade my wiring and seen people debating on this some people say they have had no problems others said it's a ticking time bomb I'm leaning towards termination and fuel safe wire I'm sure it gets blown out of proportion though.

I bought the aeromotive stealth 340 fuel pump but there is a pigtail that is molded into the top of the fuel with 16 gauge wire seems the only way to do that mod would be to cut the 16ga wires and solder them to the 10ga but that doesn't make sense did they redesign the top of the fuel pump although there are two little silver what looks to be positive and negative females where you can plug a male bullet connector into each one but they're very shallow so I don't see that working any suggestions.

$2000 worth of information..!!! With the new wiring kit they now have for available..!! One question do you need a return style regulator to make this work??

Hey buddy on my 4cyl notch when I swap 2 my V8 should I use the V8 pump or just go ahead in run the 4cyl pump for now just put V8 lines with a fresh filter I am going to be running 24# injectors I have the 87 notch 4cyl but I have the full 89 engine harness I bought a lot of my stuff from Tim @ pony performance 👍👍great guy! My donor is 92 GT so I have everything I need I have a al9 computer it works great! I was wondering about the fuel pump cause I have a lot of work in head of me lol! In when u swap a aod car when u do the clutch pedals do you have to take the whole steering column out? Yeah man I keep buying everything I need so I will be ready when the day comes! U Neomustangs & Rodney 50Tussin are my most favorite Mustang channels on RU-vid man what if your car doesn't have a ecu ground could I use the 1 from the 92 to a 89 harness! Man like I said I have so much passion for foxbodys I ain't the best mechanic but I can get shit done! My motor came out of a SN95 it has the 3 g alternator I have to remember that cause I a going to drop it in with the SN95 pulley set no a/c delete or smug pump delete sorry about this long ass message I am guy just trying to get ready for this man believe me I appreciate any of ur knowledge & no how I know u are so far advanced on Mustangs i feel ashamed to ask you some of these questions! Thanks a lot Neomustang look forward for your videos!

Did you bypass the inertia switch? Thanks

What type of wire are you using?? Just regular 10 or is it Teflon insulated 10??

My aeromotive 340 pump doesn’t have positive and negative terminals going into it. How would I attach the 10 gauge wire into it?

do you look for wires with insulation that's petroleum or gasoline safe? i would hate for the insulation to dissolve off and short out. thanks

Good informative video! You could also do this to a sn95 hanger and slap it in the fox tank right? Seeing the sn95 is 3/8 feed vs the fox 5/16? Or is it not worth the hassle

What did you use for the quick disconnect?

Liquids Per Hours

I'm curious how much liquid is in a liter? J/k Great video

Do yo know how long those grommet last?

Is this worth doing on a 255lph pump for my NA 347?

Wil I need to upgrade my fuel system I’m doing a 2v swap on a 85 2.3

Does anybody know where the fuel pump is grounded? 93 vert GT

You kept saying run the wire from the coil but I think you meant to say starter solenoid. Just wanted to clarify for the people who may be new to this.

Looking for a electric fan and a wire install video

lph means liters per hour

Aeromotive fuel pressure gauge upgrade..

What's up Neo with no reply? Need a little help.

*liter per hour...

Combulated = corrugated tubing, lol.

Way to many ads😵

You could use the factory wires that powered the fuel pump to trigger the relay. I would also suggest removing the plastic cap for the terminal and solder it instead of crimping. Just a person thing. I hate crimp connectors. Good job and thanks for posting!
