How big of a fuel pump to go?
Complete newbie here. I have a stock 1990 5.0 convert except for a cold air intake, an 80mm MAS, and Ford Racing High-flow 19lb injectors. My fuel pump quit working and now I need to get a new one but I'm not sure which brand to go with or what size to get. In the next 6-8 months, I was planning on installing a Cobra Upper and Lower intake.
Thanks for the help. |

Why such a big MAF?
Anyway, a 190 would be fine. |

I was wondering the same thing.

How do you know it's your fuel pump?

RE: How big of a fuel pump to go?
I say 190 also. But 80mm maf is huge!

RE: How big of a fuel pump to go?
I told my mechanic that I was planning on installing the Cobra Intake and he suggested the 80mm MAF. Is he wrong about that? I think its the fuel pump b/c when I start the car the RPMs wont go past 500 and the fuel pump is really really loud and there is a popping sound and then the car dies out.
Do youguys think it is something besides the fuel pump? I haven't checked the fuel reply yet. Also, would I be better off going with an inline fuel pump instead of an intank one? |

No stay with the intank. And when is the last time you changed your fuel filter? |
RE: How big of a fuel pump to go?
I changed the fuel filter about 5 months ago but the car did sit for about 2.5 weeks with only 1/8 - 1/4 of fuel in the tank.

You'll prolly want a 65mm TB. I wouldnt go higher than that. You dont a anything bigger than 73-75mm on the maf. I dont guess the 80 will hurt it though.

People have asked if I have a cam in it b/c of how it is lobing. It sounds like it has a cam but it just idles rough. Could that be b/c of the 80 MAF?
