Well im going to upgrade my saleen and going with a 65mm pulley,42lb's,90MAF and I need a fuel pump..im told to get a focus pump but can anyone tell me the difference between that and the walbro 255?? is a 255 fine or not? im looking to make around 350rwhp
the Focus pump will work great for you. it's returnless and only costs around $100. it also plugs right in. the Walboro does not. i'm making 380rwhp with no problems on the Focus pump.
