Re: My 1980 Sierra LWB build
I repaired the fuel pump wiring and it ran for another week. I went to fire it up yesterday, and it was running rough and backfiring (slightly), and found that fuel pressure is running low...so I may have hurt the fuel pump, and even though people have run the same EP241 pump (used in Camaro/Corvette TPI applications) that I am, I'm thinking I need to run an EP381 pump (used in 350 Vortec trucks)
So, for now, I'm gonna park it until I get the new pump installed
