Fuel pump for 1996 Polaris snowmobile engine?

i have a friend who wants me to putt a 1996 polaris xlt sp 600 three cylinder snowmobile engine on a show off/parade tractor.
The vacuum fuel pump is shot and i cant find a new one and cant use electric fuel pump.
Any one have an idea on how i can rig up something?

Why couldnt you use an electric pump?

No battery no charging system.

Maybe a diaphragm pump? I read the earlier polaris 3 cylinders had crank bearing issues. Does it have the oil tube to the bearings? i believe it was the ones on the PTO side. Is this the mono-block? Or are the cylinders 3 separate castings? The mono-block with the 3 into 1 exhaust manifold seemed to be more reliable, since it was tuned to less power? the mono-block with 3 separate exhaust pipes to a can and the block with the separate cylinders had more power, thus, higher wear.


......Did I mention that sleds are my other hobby? lol

Haha man there's always room for another hobby. What's stopping you fitting a pulse pump?

Wait what? I wrote that lol.

Whats wrong with a pulse pump for like a briggs? that should move enough fuel right? or make a manifold with a single carb since you won't need all the power of a polaris triple.

MY BAD:hillbilly:

No worries. Yeah CQ that's what I meant, you can buy a plastic one for about $10.

lol ill pull one off my mower and try it.
P.S. After i try gravity flow.

If you have the fuel tank higher than the carb gravity will pull the fuel down.

the gravity flow works good.

Nice, saved you some $$$

Mikuni makes vacuum pumps for singles, twins, and triple cylinder engines. The twin and triple pumps look almost the same except there is one extra outlet for the triple.

That's usually the time I take my work back.

lol he is pissed off! i have around $100 in parts on the thing so i called his dad.
(he is 17 and im old enough to be his gpaw) well his dad stopped buy with a bill of sell this afternoon. its now mine.  

This is tuff love. he quit school and his job. he had no intentions of having me do the build. he just wanted me to get it running so he can sell it. 

hmmmm......I wonder what you can do with it

Does it have the torque converter with it? That would make an AWESOME go kart engine!!!

Stuff like that is always cool. You could probably sell it and make some profit.

One of the youngins came by and started talking about all the upgrades to the motor and suspension... and concluded "it was customized for racing" the one big mod he pointed out that should have stuck out the seat was professionally cut down to a one seater

Well as he is my favorite nephew i gess i know what hes getin for Christmas.
unless someone stops buy and offers stupid money for it

LUCKY!! haha, i guess i don't need it, I already have a polaris sled anyway. 1995 polaris indy 500 with the phenomenal 488 fuji liquid. Love that thing. The big difference between the '95 and '96 is the suspension. '96 is way better. My dad has the same thing I do, only a '96, and we've beaten the crap out of it. Never fails to to run and still goes 80. 5700 miles on his, 2300 on mine.

Lucky nephew! Always wanted a sled, pity we don't get much snow here
