Jrwhite3230 Posted December 17, 2013 Share Posted December 17, 2013 Is its possible to install an exterior high performance fuel pump for the inline 4.0 six cylinder engines,instead of internal ? does anyone know the fuel pressure rating is for the inline 6 cyl eng, also will the regulation be a problem if I connect the exterior pump up to the interior pumps harness? and take out the interior pump and runn hose through to the sock/filter leaving only the sending unit in tank. thanks for any replys p.s: if this would work does anyone have a clue to where I could locate and exterior pump Link to comment Share on other sites More sharing options...

shaved ice Posted December 18, 2013 Share Posted December 18, 2013 I just put in a Delphi fuel pump for my LWB '87 that I ordered from Autozone. It looked a little different and I had a little difficulty installing it (because I did not drop the tank), but it worked. I just started and drove my inherited MJ for the first time and I couldn't be happier. Link to comment Share on other sites More sharing options...
