Fuel Pressure Regulators & Why They're Important 

That’s good to hear. This regulator has a lot of good reviews!👍🏽

I'm glad I just saw this video. I just now bought the exact QFT fuel psi regulator for my Holley lol. Thanks for sharing I'v doing it old school

I had my carb set up with a regulator with return line and could not get the pressure beyond 4 pounds on a unit said to put out 8. I pinched off the return line and not only got almost 7, but was able to regulate it down to the 6 required for the Edelbrock. So so much for the ills of deadheading.

For the occasional hot rodder, I highly recommend a good fuel regulator and, AND an EGT guage to monitor and diagnose your motor while gassing on it. You can hurt a good engine with too much fuel (washes cylinder walls and damaging rings, not to mention loss of HP), and too little fuel (extreme combustion chamber temps melting down many costly parts). The old saying, "Lean is Mean" is as true today as it was way back in the day. We used to search for the perfect temp by reading plugs and slowly jetting down to get safe and undamaging power. The EGT lets you find it quickly. Some just use lights connected to an oxygen sensor. That works great too. using all of these is best for me. Udn Udn.

Great tutorial

Woulda like to see it in action with quick adjustments showing change on the FPG. Great video though, very informative. Thanks.

great video!

Great video! Very informative. Can a person mount a fuel pressure gauge directly to the Quick Fuel pressure regulator like you did to the Aeromotive PR? Thanks.

Thx for the video.

Was running one of these for about 5 years. After time it started to leak when the jam nut was adjusted. Called them up and got free replacement. Highly recommended upgrade.

I've been messing with this crap since the 70's and everyone ran a regulator with a Holley pump back then. It's quite old news. The regulator came with the pump. The Quick Fuel Regulator is almost an exact copy of the Holley regulator and they are not associated with each other. With a Holley carb I would generally run a regulator with any pump producing more than 6 lbs of fuel pressure but some get away with more. It really depends on the needle and seat/float setup.The larger the needle and seat the less pressure you can get away with. If you need low pressure at idle and high pressure at full throttle, try this. Look at the top of the regulator where the vent is. If it has a vent hole you can apply manifold vacuum at that point and the fuel pressure will automatically be reduced during high vacuum situations such as idle. When you get on it and the vacuum is low the fuel pressure will be increased. Set the max pressure with the regulator adjustment screw with vacuum line removed.

this is one of the most informative videos so far,running a carburetor automatically means a regulator is to be installed main reason is fire,and fuel control,keeping fuel mix is paramount on a carbureted engine,otherwise fuel in the oil is a disaster,forget all the wiseass statements below this is a very good video for the average guy who is lost on fuel mixtures,don't even attempt to have your car dyno;d without a regulator installed

Great video! Good info Where exactly can I find that same regulator I went to aeromotive online but couldn’t find the one you have, if you could give me a hand thank you.

Are inlet and outlet adapter the an male flare coupler union fittings? your reply will be highly appriceated

can you add gauge down the line if you already have the second choice feul regulator?? thx

Does this model of aeromotive can be adjusted to 3 psi? My weber carb would like to run at 3.0 psi.

good video my brother

When you say fuel injected pressure gauge are you referring to a throttle body and electric fuel fuel pump with injector's? Cause my car has eldebrock carb with electric fuel pump on a vortec 350 my psi is showing 9-10 psi at idle.

I'm about 6 psi... when it's cold and running its fine but after i open the throttle it seems to do fine but once i go back to normal rpms it seems like it continues to dump unnecessary fuel and it begins to bog down and conk out??? Do you have any suggestions?

What fuel pump do you you use? Do you use a high pressure fuel pump like 60psi with a regulator? Would that work or do you need the low pressure fuel pump like 7 psi? I bough a low pressure pump for my 65 mustang and it is so load I hate it. Looking for quieter options.

What is the part #s for your regulator? and gauge? and size fittings? Nice looking setup

Is there a return line to the tank? If so which side?

Great factoid video.

if you choose to run 60psi would that require you burning more fuel at idle ?

What do you do for return?

What product number is that? Did it come with the gauge?

I set my regulator at 4.5 now it’s reading 2.5 new fuel pump inside tank I have a holly carb 350 motor (should I replace the fuel filter)

I have a wrx and it came with one of these and now it makes a weird as noise and car wont go over 5psi when max is 17. i dunno. ill have to look at it a bit more

what about the return fuel pipe is connected...???

Holley recommends one regulator per carburetor. First, check your plugs for rich-mixture fouling. Bad O-rings on needle and seat assemblies will also cause flooding, plug fouling, or even fire--ouch.

My new Edelbrock #1406 says no more than 6psi at idle. I am installing a new mechanical fuel pump and it says it is rated to 9psi. Everything is Stock Replacement parts. Should I get a regulator before installing those items?

So I have been having issues with mine I have a pretty close set up ass yours. So I can’t get no more then 4 psi on my gauge change the fuel pump put a new one same result. As it sits at 4 psi it wants to turn on at first but after cranking you the guage go to zero. I have this on a 93 Chevy truck do u know if there any kind of filter on the tank that might be restricting the gas?

On that style can the extra port be for a return fuel line I have a dead head system and I think it maybe causing problems since the nitrous was added

90 bucks that's a steal be a couple a hundy round here,nice engine bay

is it possible to reset a fuel regulator?

I have a Holley nonadjustable carburetor 600. I'm running a stock mechanical fuel pump. Do I need a fuel pump regulator?

I've been having flooding issues after fuel pump change, I believe I need a regulator.

Ok so, if you have the Fuel Y'd off for the Nitrous,, does the Nitrous side have a regulayor as well?

can you use blinker fluid in that gauge?

What is that blue piece sticking out of the right hand side? Sorry but I have never messed with AN fittings, lines or regulators.

So you used that regulator for your nitrous pressure as well?

Does this Quick Fuel regulator have a port for the gauge?

Where can I purchase a 15 psi low fuel pressure regulator with gauge like that one ??

My new carb requires certain pressure. It runs much lower than fuel pump is pushing. I built my regulator for about 50 bucks.

that engine look good i wish you would have put the camera on your engine like to see it

My FI has a built in pressure regulator.

I run on 8.5

The second valve you show is not the same, where does the fuel gauge go? Dohh

The liquid is going to heat up and give a bad reading on the gauge

do you have to run a return line...i have a fuel pump that is at 60 psi and I'm running a holley carb that is taking only 7 psi...should i run a return line

I see you have the adjuster turned all the way in. Maybe you don’t need a regulator my friend

3 psi all u need

Run an electric fuel pressure gauge into the vehicle where it can be monitored while driving! You can only monitor that under hood contraption with the hood up and no load on the engine! No bueno! You need to know if you have fuel pressure at WOT.
