Car struggles to make fuel pressure

Mitco39

I would take you up on the offer if my car wasn't currently strapped to the dyno. Id love to send it to you but I think I will just try to modify this one myself since I have another one coming in a week or so. I cant imagine I am doing anything wrong as I can apply 50psi of air to the outlet port and she holds, and I can confirm that when I shut off the car it holds fuel pressure with no issues (after fixing that oring). I am going to do what you said and bypass the basket filter and put a inline filter in the car. So it will go straight from the pump through a inline filter and to the engine, then back in through the venturi setup. I am going to try and remove the factory filter from the basket to allow for more fuel to sit in the basket.

I just went out and bought all the parts to do this, if I didn't want my car for the weekend I would have sent you it. If I do this and its still dropping off then my next place to look is the wiring, which could be the issue with the repeated higher pressures that the 1:1 regulator puts the pump under. I am also going to turn down my pressure since I am only hitting ~60% duty on my injectors so far.

Ill take some pictures, and you can see (in horror probably, lol) the mess I am going to make to try and fix these issues haha. If this works then ill have another basket to maybe try and see if I can fit it in the other side and have another pump T into the outlet inside the tank and run 2 pumps (one from each side) in parallel together. This would also act as a transfer I would think. But thats in the future.

I do appreciate all your input Charles, if you dont mind what is your baseline pressure set at?
