Hi everyone.

I am planning on fitting a Walbro 255 fuel pump and some yellow 440 injectors before remap and was wandering whether I would need to fit a fuel regulator at the same time?

Thanks

 

I wouldn't think so

 

i havent ha, the stock FPR seems to be ok so far

 

you`ll be fine. I`m hitting my injectors with 97-98% injector duty and everything works fine. Stock fuel pressure regulator is kept. Had it for nearly 1 year. If anything you need bigger injectors depending on the power you want to run.

Specially if you have a phase 1 to 1.5 fuel rail, you already need to pay £40 for adaptor kit. and for £60 or so you can get adaptor kit for the newage top fed injectors wich are 550 cc or so and much better. (i will do this soon).

 

LOL. this seems like a very scientific and precise process
