Walbro 255lph Fuel Pump into a 99?
I've googled this, found a few threads on NAXJA & JeepForum but they are either unfinished or pertaining to 95 and older XJs with a return line.
Basically, I have a Walbro 255lbh fuel pump that I intended to use in my Subaru. That car is living in Knoxville with my parents as of late and I'm here in Miami with the XJ and I've been thinking - I could swap this fuel pump in and breathe some newfound oomph into the old girl.
My question is will this pump be too much for a stock 4.0? Also, is it even possible considering the 99 is a returnless fuel system?

No. You may overwhelm the system and run pig rich.
