No fuel from the tank....

Hi Guys,

So i have a 1300 xflow in my striker.
It's using the mechanical fuel pump on the engine.

I have had the engine running with no problems so far, but i think last time i tried to start i was out of fuel.
Anyway, just fueled up again today and the fuel is getting nowhere.
The fuel filter is just after my tank, and i'm not seeing any fuel going through, definitely nothing going to the carbs.

So are mechanical pumps likely to fail?
Is there any easy way to check?

Thanks,
Andy

yes.

remove plugs, disconnect the hose to the carb(s) and whizz the engine over. if after 1/2 minute there is no fuel, either there is a blockage, no fuel in the tank, a significant air leak in the hoses or the pump has failed.

yeh i've already done that, as said, no fuel coming through at all.
just trying to establish how i can tell it's definitely the pump, although i don't see how it could be anything else really...

Is the fuel pipe coming out the tank at the top or the bottom ? you may have to prime the system if from the top

from the bottom sir

If you remove the pump from the engine you will see a lever which acts on the camshaft lobe. If you move it up and down you will see fuel squirt out of the pipe going to the carb. If not strip it down you will probably need a repair kit as the diaphragm is damaged.

cheers macc man, that's what i was kinda after.
I will rip it apart and see what's going on.

Could the pipe be blocked with crap how about blowing down the pipe from the pump end not though the pump ?
Is the air hole blocked causing a vacuum in the tank?

fair comment, i don't see how it could be blocked, it's never even seen the road, only been ran still, and everything else is already sealed. But saying that, a nice easy test, i'll give that a go first!

common problem is alluminium particles in the tank from the drilling and cutting out for the sender unit. followed by sealand used on the afforementiones. Blow back into the tank via the fuel outlet I would use an air blast gun this may clear it but it will return if its not fully cleaned out
