twin pump install problem
twin pump install problem Ok here is the deal, I installed twin pumps and when both are on I have 80lbs of fuel pressure and the car will barely run and it throws my nitrous tune way out the window? Any reason for this?
What is your fuel psi on one pump? Did you drop the tank or cut a trap door? Is it a 98 or 99+ car? On my 98 without the bucket i could see a second pump getting in the way and possibly kinking the return line from the regulator. But I think mightymouse is right, you smashed the return line, its pretty easy to do if you dropped the tank.
