I didn’t really know whether to put this in the NA to TT section, but I figured I’d put it here. So I did a NA to single turbo conversion, and I have 360cc injectors and what have you, but I’m looking for a higher capacity fuel pump to back up the newfound power. I’m trying to find something that’s a drop-in upgrade for the stock NA fuel pump. Any ideas? If I have to modify the sending unit I will, but I’d rather not have to. I know the Walboro 255lph pump is a drop in for the VR4, but the VR4 and NA pumps are PHYSICALLY different, no? Thanks for the help!
Most of the new pumps are a drop in replacement for the NA fuel pump assembly, same size and same connector, most of the mods are related to the TT fuel pump assembly since it had a larger pump and different connectors.
So I found that the Evo VIII fuel pump is the same as the NA 3000GT fuel pump (Stealth316), and the Walbro GSS342 is a direct fit for THAT pump, so by the transitive property I learned in geometry, the GSS342 is a direct fit for the NA fuel pump, no?
