Anyone know what the PSI is for a fuel injected f-150 rear tank pump is? Using a Ford tank with my Chevy 95' 4.3L and it won't stay running :(

I have a question as well...do single tank f150's have a low pressure in-tank and a high pressure external like the dual tank versions do, or do they only use an in tank? This may be your problem if you're using a tank from a dual f150

That makes sense. I just put in the big plastic F150 pumps and the truck fired right up.

majority of the in tank pumps run about 80psi at the pump... unless its dual pump system

yup, '89 is low pressure pump in the tank to prime the frame rail pump, the pump on the frame rail is about 55psi.
