My fuel pump died so I went to my local parts place and got a new pump. Now my car runs like crap. I am wondering if anyone can tell me if this part number F8OU-9350-AA is the stock fuel pump. I got that number off the old pump. But I never checked to see if the pump I put in had the same number on it. Seems like the car is starving for fuel. Filter was also replaced at the same time.

 

Is that right off the pump or the fuel hat?

 

Right off the pump. I was in touch with the ford dealer today and he couldnt find the number in his computer. I'm really stumped.

 

All i can find is a Chinese manufacturer selling them. Looks like a generic ford/gm pump. Grab a nice Aeromotive 340 lph and drop it in there if your concerned

 

Yeah that's the same thing I found. The pump I put in is new and don't really want to have to take the tank down again. Its a pain in the ***. But I will try a few things first and will post updates for anyone else who might have the same problem in the future. Would there be any complications putting in a higher flow pump. I'm running approx 325 rwhp.

 

Ok. So I took the car for a rip this morning and for the first two minutes it ran great. No missing power and no hesitation. After that started to hesitate again then all of a sudden speedometer, tach, odometer, and temp gauge all stopped and had no power. Engine was missing bad at this point. 5 seconds later everything came back on and only had a small miss. 1 minute later it happened again. So I got it home and parked it. Any ideas. Anyone have rhis problem before.
