1985 J150tlcos, running premix, Which fuel pump?

[johninok]

Bought the boat used, previous owner did away with the VRO system. I am almost sure that I need new fuel pumps, motor bogs under load, pump primer bulb, runs great.
All I see are two fuel pumps hooked in series. Cant find any fuel pumps on BRP parts finder. Can I use any V4 or V6 pumps? I bought some rebuild kits but the diaphram bolt holes did not fit with the pumps I have.
I have checked alot of online parts stores, and am getting a goosegg. Any help would be awesome,part #'s, or? thanks, John

Not unusual to have the VRO type pumps replaced by the older style double in-line pumps. You need to look at a V6 parts list from an older year engine, like a 1983 model. The pumps listed there are common on most early V6 engines. The current part number for the pumps has probably been superceded a few times, so see your dealer. I don't think those pumps have factory rebuild kits. Note that the pumps have different part numbers between them so make sure to put them on correctly. Stick with the V6 flavor pumps only, as you need the fuel volume. Here are two early part number that will get you started: 393648 upper and 393650 lower. Also, make sure you only use 3/8" hose line from the tank.
