The 255 is because a 351 is planned for the Daddywagon. I need machine work etc. I am running the 24lb injectors and mass air intended for the 351. I figure with the return setup it wouldn’t matter.You think maybe a 225 lph pump is a little big?
What approximate hp you got?
Whats you fuel pressure?
Can you check codes?
Good to know!! Thanks! I just got done driving around with the new fuel tank. So far so good. It makes power and smokes a lot so I am going to do valve seals. It’s a stock 1986 5.0 motor so it’s probably due.You'll likely be ok, just don't run it low on fuel alot, fuel can get hot going round robin at low levels.
A while turned out to be less than two years. This problem has returned. The car died on me just after I filled it up last month. Because I could not hear the fuel pump priming I assumed fuel pump. But I heard ignition module causes similar. So replaced module and car ran for about 10 minutes. I was convinced once again that fuel pump about to give up. I ordered pump. I dropped the tank and found that high resistance or over draw amperage caused intermittent contact failure at bulkhead connector for fuel tank on the ground wire. Now I need sender assembly as well. I will put up pics soon.I dropped the tank and the pump works just fine. Apparently the connector at the top of the fuel tank popped off... I think. Well I messed with the sending unit and put everything back up with new straps. I drove it... again. Back in business... forba while anyway.
