Sr20 fuel pressure prob

[sr kid 88]

Ok need some input people. My car is gettin tuned right now on e85 and my tuner told me that my fuel pressure keeps failing so he can not complete the tune till this problem is fixed. The car is a fully built sr20det top to bottom. We already put a new fuel filter and Areomotive afpr. I have 1250cc injectors and a single 255 fuel pump. Gonna try a new fuel pump Friday and see if that's the problem. Any other suggestions? Thanks in advance

I have 1250cc injectors and a single 255 fuel pump.

I don't think that a 255lph pump can move enough fuel for those injectors. Guessing that your running about 25 psi of boost, you'll need something that can flow up to about 400lph at 75psi if you are running up to the limit of the injectors. I'd check out Aeromotive's A1000.

Yeah that's what I was thinking. Ordered the Bosch 044 to run it inline with the 255. Thanks for the reply

That was the exact setup I was going to recommend.
