willo88 Member 700 Member For: 12y 10m 20d Gender: Male Location: Newcastle Posted 18/07/14 03:18 AM Share Posted 18/07/14 03:18 AM 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.(Apologies if this has been covered elsewhere, but the search function isn't working with tapatalk) Link to comment Share on other sites More sharing options...

Ideally that's what I'd want to use but it's a bit overkill for what I'd need. I'll just go the cheaper option 255 1 Link to comment Share on other sites More sharing options...

I did ask the question about the reg and the reply was "see how we go" Elsewhere on this forum upgrading reg when upsizing the pump seems to be a definite must, but I have every faith in CMS!!

Although I did go tune right after due to injectorsThe 460 goes into factory holder with a few slight mods Link to comment Share on other sites More sharing options...
