Have a Question

Just wondering have a friend that told me about someone putting a resistor in their fuel pump and he said it makes it lope like a motherf'er. Didnt know if anyone could help me out on if you can do it on a 7.3L and about to add a FASS system will doing that affect the FASS system? If you can let me know how thanks...i know how to put one into the ICP sensor but i wanted to try the one in the fuel pump or is putting one in the ICP sensor safer?? THANKS!!

There is nothing you can add to the fuel system to make it "lope" ie run like ****...

Your friend is confused.

Let me explain the 7.3 fuel system to you...

You have a fuel pump...

It gets 12v when you turn the key on. It stays on all the time when the truck is running...

It pumps to the fuel bowl which then goes to the heads. On the return line there is a mechanical regulator that keeps the pressure at 50-80psi.

There is NO way to add ANYTHING to the fuel system to make your truck lope.

As I said before, your friends are incorrect.

It's Not the fuel pump, but the HiPres oil that drives the injectors that can be effected with a resistor, CSIPSD is right - you ARE confused

You should find other people to listen to about your truck

Get back all you want, there is nothing you can add to the fuel side of our trucks to make squat differance.

If you put a resistor inline with the fuel pump you will lower the voltage at the pump causing it to spin less rpm which will cause it to pump LESS fuel.

Maybe they are starving the truck for fuel which makes it run like azz???
