Fuel Pressure Regulator: How it Works

Рет қаралды 56,428

Күн бұрын

Today I’m installing this fuel regulator. I’ve had a FiTech EFI but I’m switching to the Edelbrock Pro Flo and they don’t want as much fuel pressure. So I’m going to install this fuel regulator.
Buy one here: amzn.to/2LQoso5
If you are looking a buying one, a couple tips:
1. Stick with a trusted name, don’t go and get a Chinese knock off. Go with a Holley or Edelbrock. You don’t want to go cheap with your fuel.
2. Get one with PSI for Carbueretor or EFI. If you are running EFI, the carburetor version won’t work. But mine is capable of both.
3. There are two versions: Regular or bypass. Mine is a bypass.
4. Inlet outlet size. I got -6AN because my fuel lines are all -6 AN.

Thanks. I got my answer from your video. I don't need to hook up the vacuum port as I have a TBI and the injectors are above the butterfly. 😊 Just need to figure out if the fpr can be adjusted down to 13psi now. I assume I turn the nut on top counterclockwise to lower the psi? Only thing is, my fpr regulator has two nuts on the vacuum port. Do I leave the ignition off with key on only to adjust? Thanks for your help. Great video.

I bought a fpr. How do I adjust the psi down to 13psi as it has a vacuum port on top. Do you know if it's manifold vacuum or port vacuum? Is the vacuum port necessary so the fpr will work properly? Thanks for the video.

Question: my pump only makes 7psi max or 90 gph at 5psi. I also installed a regulator to have a return line in the system. I set the reg on around 5 psi and I wonder if the reg will ever opened because of the low pressure or in other words the system cannot create overpressure. Am I wrong?

Should you use #3 bypass system described on a carb setup?

@jameslong5964 3 жыл бұрын

My fitech internal regulator has failed twice ! Im running a efi tank with in tank pump(255 walbro) . In theory could I run the external regulator in your#3 system? Btw great video! 👍

Awesome video! How much was your regulator? Unfortunately I am at the point with my Fitech where I may just put the carb back on to drive it (simply don't have the money for the edelbrock, or should I say the money for the divorce after buying the edelbrock). Problem is i have the Sherman tank with in-tank pump which is too high for a carb, thus I will need a regulator. Thanks as usual - always awesome info from you!

It was about $150, I put a link in the description to the one I bought. Check that out

Did the EFI spring come with the regulator or did you have to get one? If you had to purchase separately what is the part number of the spring. Thanks

so i had a plugged FPR vacuum hose and unhooked the hose on a new regulator hose was plugged for whatever reason making me think it was the FPR so when i went to unhook the FPR vacuum hose it was very hard and stuck on there like it had suction. when i pulled it off it kinda made this hissing sound now my tahoe wont crank and doesnt get pressure at the rail at all. im assuming i accidentally pulled it wide open or was bad to begin with and is now stuck.... oh the joy.

im gonna fuel inject without efi 2 cylinder lawn mower tractor engine just for the experience i know bit about electronic and i want to build a weird electronic system that ain't an efi computer and im currently building the fuel system my first though was #3 xD but i bought a no return type regulator T_T i have question what the diferance between return and bypass ? still wacthing video at 7:34 at this moment i have a though on #2 i would put a valve on the return line and close it until pressure get created and flow still occure but still why you would want flow in and out of the rail ? beginner here xD #1 was my choice because my fuel ump can reach 140psi X_X i though i would burst those cheap clear tube i was using for testing

I know this was about fuel pressure regulators....but for those of you watching to learn, don’t forget your 100 micron pre filter and your post filter...in my case 10 micron

I don’t know why you even put option #2 in there - it isn’t an option as the car wouldn’t even run.

@NashvilleEarlyBronco 2 жыл бұрын

It’s the “non-running car” option. Very important for some people
