    WTB: Old School 1100 Fuel Pump ("The Pentagon")

    I had some trouble getting check valves installed in my existing one and I ran out of check valves before getting it right. Roost put the idea in my head to take his (gently used) fuel pump off his hands but now he can't find it.

    I thought I might try and see if anybody else had one that they want to get rid of before I either get some more check valves or send my pump off to another member to have them do the installation for me.

    This is a pump for the 1100 motor, I've got tripe Mikuni 38's, but there is a single external pump that pumps fuel to all three carbs instead of there being a pump for each carb like there is on some of the other models. It's in the shape of a pentagon, and I think it has 3 ports on it (fuel inlet, fuel outlet, pulse line from block).

    Let me know what you've got. Thanks!

    ZMANN: I knew they still sold them new, but I'm always looking for a deal so I can afford the cost of fuel! The kit was an option, but since I've already ruined 5 check valves and pegs, I'm not confident that I can get it done right this time either (I really don't get what I'm doing wrong honestly, I just can't get the pegs in without ruining them).

    My pump is actually in pretty crappy shape anyway, so that's why I'm hoping I can pick up one that's in better shape.

    To install the pegs.. lube with 2-stroke oil and insert with a 2mm ball-allen wrench. Or any other round nose object.
