Milo500 Posted July 21, 2016 Share Posted July 21, 2016 Hi Guys, Am going through a single conversion from TT to about 500bhp. I have got a walbro 255lph and am wondering, will it run fine after putting it in, or does it have to be tuned straight away? I am getting it fully tuned soon anyway, but can I put the pump in now? Surely the fuel reg will keep everything the same? Cheers, Tom Quote Link to comment Share on other sites More sharing options...
Wez Posted July 21, 2016 Share Posted July 21, 2016 You can fit a fuel pump, the Walbro 255 is normally recommended on JSpec TT that have gone BPU anyway as the stock pump isnt that great. UK/US stock fuel pumps are a bit better EDIT: just to be clear, its only the pump you are changing, your not fitting an FPR or raising the fuel pressure?

Chris Bailey Posted July 21, 2016 Share Posted July 21, 2016 Walbro 255 pump is good for 550bhp on stock fuel lines, we had a 255 pump and SARD 650cc drop in injectors and maxed the fuel setup out at 550bhp. Quote Link to comment Share on other sites More sharing options...
j_jza80 Posted July 21, 2016 Share Posted July 21, 2016 Just avoid the Bosch 040. It's a good, reliable pump, but is far too noisy for road use. Quote Link to comment Share on other sites More sharing options...

I have a single 255 and only started to run out of fueling around 570+ and that was with 650cc drop-in injectors, stock rail, lines and FPR with the pulsation dampener still fitted. Walbro now do some nice E85 450lph pumps which are E85 safe Quote Link to comment Share on other sites More sharing options...
Milo500 Posted July 21, 2016 Author Share Posted July 21, 2016 Brilliant, thank you for all of the feedback...yes I am just putting the pump in, not changing the reg or anything at the moment. I am putting the 650cc saRd side feeds in when being tuned only going for 500bhp as it's auto...but is enough for me om the road Quote Link to comment Share on other sites More sharing options...
