odd intermittent fuel pressure problems

[Gilbee01]

Are you using a 2.9 pump or the one for a 3.0.. If you went with the stock for the 2.9 you will have nothing but trouble. I had similar issue and ended up buying new tank and pumps ( some kind of crap caked the inside if my tank) go with premium pumps no cheap knock offs. And flush the fuel lines before install. Idle could be the TBI sensor . Replaced that twice. And are u using the 2.9 ecc (pcu)? I reccomend getting one for the 3.0 and relocate to a cooler area not on firewall

I swapped in a 4.0 out of an explorer, the tank was clean inside when I replaced the pump the last time, admittedly it was a cheap one, which is why I think it crapped out this time. Other than that it runs really well, I don't really have an idle problem, besides when I only have 10psi of fuel pressure, pretty understandable that it runs poorly then.
