Righto. Thought it was time I upgraded the intank pump in my fuel system. Currently have a PW twin 460 surge that is more than capable on p98. On e85 I question the ability of the stock intank pump to keep the surge full under WOT. Looking at getting a Walbro pump put in the standard intank pot. Question is size? I've been told the 400lph pump requires some modifying of the standard pot to fit, whereas the 255lph and 300lph will slip straight in. Any advice would be sooper dooper.
