#75225, "RE: SFMU question for ALL" In response to In response to 0
Originally posted by DSMeclipseGS Hey guys, on the side of your SFMU there is the boost, bleed, and vaccum ports. Can everyone explain to me what each does and which ones need to be plugged up/not plugged up with something? I've ben having problems with my fuel and I want to double check everything. Thanks a lot guys.
this needs to be search but here you go.....the instructions are very clear too
Boost is a ceiling limit for pressure if i recall vacuum is for the pressure when the engien is idling with vacuum hose connected to the port. bleed is in case you decide to buy and used the bleed valve.
