HOLLEY SNIPER EFI - Installing an Electric Fan and a Fuel Pressure Gauge!! 

I wanted to take a moment and express my appreciation to you for posting this. I'm diving in to wiring and installing electrical accessories and it's still new to me. This made it easier to understand. I have an aluminum rad with two fans and bought a 40a relay on Amazon. Wish I'd seen that Mr. Gasket one, but I think what I have will work.

Nice video! I used an 18", two speed Derale fan and used the dual fan output to control the two speeds. Works fantastic! BTW, I get 58 psi before the eng even starts.

Dude thank you so much we been messing with these fans for hours

👍🏻thanks

Should I add a fuse to the battery wire before the relay, or is that not needed?

I'm setting mine up now and just used the same gauge but used a barbed inline connector right before the unit. I havent turned it all on yet so not sure how it will work but should be fine and I should find out probably Friday when I hope to be ready for 1st start up since 2005 in my 1970 442. I may have posted a video on my channel I cant remember if it was included in the quick look over vids I posted

Screw the probes, you’re right it’s a ghetto solution. Use a thermostat style fan switch in the cylinder head. Works just like a thermostat except instead of opening a passage way for coolant to flow it closes a switch and provides continuity to ground for the control side of a fan relay, exactly how the sniper system does. However with the sniper there’s no need for one of those, I eliminated mine when I installed my stealth system. I’m just saying the probes suck, never used one, never seen one, I always used the cylinder head mounted fan switches. I hate that style gauge too personally. I put one on my fuel pump outlet, brand new pump it reads 50psi but I’m not really doubting the pump yet. I’ve had multiple gauges like that, you pay out the nose for them and the longest I’ve had one last is a year with the old carb setup, one dies within weeks, one never even worked (this one may make #2 DOA) so I finally went with holley’s sender and 2.5” electric gauge... sender worked but leaked fuel from the start. Chinese quality for American made prices. Tired of it. It’s far too prevalent in the automotive aftermarket these days, like my latest garbage MSD blaster coil outperformed by the factory coil...

Cool. When i get my efi i want to get as many accessories as possible without spending too much

I hope you got a fan shroud,since the fan will only cool that one section while you are stopped.

Good and VERY informative video. What have you done to upgrade the amperage and be able to run all the newly added electronics?

did you use teflon tape ?

Dude I totally fvck with your vids...I know these are a couple years old but your explanations are on point and I've been working on cars for 16+ years now professionally. Great work

Stick wit carb. Save that 2 grand plus

Great video... sry for the stupid question but I suck at wiring. So there is no need to ground the relay itself? Just the blue wire from Holley system to 85 good enough?

Putting in a fuel pressure gauge there only tells you if your fuel pump in the tank is working. What about if the built in pressure regulator goes haywire? You still won't be able to diagnose that right?

So how were you able to get W.O.T. with the stock throttle cable?

Did you use the ground wire coming from the fan? Or you just used the power wire and let 85 on relay be the ground to cut the fan on at set temperature? Great video!

I would buy a 40amp relay with built in fuse for cleaner install. Buy online and save.

What about oil pressure

what drop filter are you using for your air filter?

Does the fan is ment to push air towards the engine correct?

How do you like the sniper kit over all.Would you still buy it knowing what you know now..

What fuel tank are you using? Nice truck, thanks for the video

Screeching Weasel?

Electric fuel pressure gauge, read from cab.

Awesome video man, really cant wait to hook mine up! If anyquestion I'd like your email in case i have any problems

get the holley pressure transducer and you will be able to see it on your display inside the truck. It's plug and play

Subbed here. Check my videos. Very cool bro. I have been told by people i trust to not leave a fuel pressure gauge in the engine bay. Install gauge and use for testing then remove and install a plug. From what i was told is that the gauge can go bad or rupture and turn your ride in to a flaming torch. Looks like u could index that fitting a bit to allow gauge to sit sideways. Im also running a small block with sniper. I tend to like to keep motor under 200 i have 160 stat and keep it 170ish i prefer to have that extra window if temp starts climbing then i have more time to be able to pull off and shut down or speed up if possible. At 200f 240 can come up really quick. Am i crazy or is this just a difference of opinions

Ramily..thanks alot helps
