fuel pump

just got my tranny, starter and everything in. i am not getting any gas, so the fuel pump (mechanical) must be out. however, there is a tube on the bottom side of the fuel pump there is no hose to it looks like there should be. is it a vacume line or something that is required to make the fuel pump work?

Re: fuel pump

Don't plug off that tube. The best of my knowledge when the fuel pump goes bad it will pump oil out of that tube. It has something to do with the diaphragm in the fuel pump. Have you tried removing the inlet hose to the carb to see if it is pumping fuel? Maybe there is some trash between the needle and seat.

Re: fuel pump

there is no oil or anything coming from that fitting or anywhere near the pump. i took the inlet hose off at the carb and there is no gas. i tried compressed air thinking maybe there was a clog from the tank to the pump, but nothing still. the zuk had been sitting up for at least 4 years. i sprayed some carb cleaner in the inlet hose to the pump and still no gas. it has a new filter. dont know what the problem is

Re: fuel pump

so when you tryed to blow out the fuel line did air come out the other side ?i'm just a little unclear on this .when you changed the fuel filter did it have gas all the way up to the inlet for the filter ? are you sure you have your filter pointing the right way(just narrowing down the possabilitys).
are you shure the push rod that drives the pump from the cam is installed back in place?(once again trying to cover all the bases)was the sammy stored with a full or completly empty tank?if not you might have a tank full of rust or a tank full of old gas that turns in to gel when it sits to long .let me know the answers to these ?'s and i will try to help all i can.zukikid

Re: fuel pump

got it going. i pulled the pump off and cleaned it up. it had alot of crusty stuff in it. slapped it back on and she fired up on the first crank. not bad after sitting up 4 or 5 years. all i need is the rear tranny brace. the one the bolts to the rear cross member. mine is cracked badly. anybody got one?
