YJ fuel tank/pump question
My 90 YJ has the 15 gallon (HA more like 12!) steel fuel tank in it. I am in the process of gathering the needed parts to do a Chrysler small block V-8 conversion with MPI.
My question is this:
I need to get a higher pressure fuel pump for the MPI setup vs my current TBI setup. Will a later 4.0 Fuel pump fit in my tank or will I have to upgrade my tank as well? I have been thinking about going with a later 20 gallon tank, but I am trying to stretch $$$$ very very tight on this one so I'm trying to upgrade only the necessary stuff.
If the later pump wont fit in my tank has anybody had any luck with an aftermarket external pump? I will have to get an adjustable fuel pressure regulator anyway so as long as I can find something that puts out about 50PSI I am good.
Thanks in advance!
