fuel pump question
 

i bought a walbro fuel pump but my stock fuel pump is bigger than the walbro is that suppost to be like that

when i helped a friend replace his fuel pump with the nippodenso one, the stock one was bigger then the replacement which I thought was odd at the time.

bigger mean what? are you upgrading to a bigger volum right? like a 190 or 255 intake correctly? size don't matter the volum per minutes does. do you have the part number for the walbro?

i have the gss317

those are the 255 . stock like 170? so your walbro is much bigger.

it doesnt look bigger but does it support better cuz i got pettit ecu dp mp cb smic intake pully soon to run additional injectors vacuum hoses redon
