Swapped tanks today - road bike onto (broken) trackbike.... Drum roll............. Freakin works!!!!! So, it is the fuel pump. Will have a look for one of those repair kits that @virtualcowboy mentioned.
you have almost earnt your cigar Andreas, but can't rule out the pump itself failing yet.. but provisionally:-
You can order it here: https://www.stein-dinse.biz/product_info.php?language=en&products_id=452298 So did I....
Initail look at @virtualcowboy linked part appears that there is no need to dig out resin etc and reseal the wires as it appears to be a complete assembly, plug and play type. Can you confirm @virtualcowboy ? Also, is it correct for a 749 fitment? Cheers.
With this kit you just have to exchange the part. The ressin epoxy is only needed when you decide to repair the part on your own. Having done both myself I would choose the replacement part.
I had exactly this problem, the wire breaks where it flexes at the point where it enters the resin. The insulation remains intact though, so not obvious on examination and can be an intermittent fault. The clue is that the fuel pressure reduces slowly, so when the engine dies it does so softly.
dont know what you were faffing about at..... it'll be the wires that are inside the fuel tank on the pump!
I thought that this includes those wires...haven’t looked at a fuel pump for a while. Time will tell.
So, I’m planning to change the wiring on my fuel pump tomorrow. Questions Do I need to take off the black shroud to be able to remove the wiring and the “bung” thing that seals it into the pump base flange? If so, how is the best way to remove the one way clip things? Also, how do I take out the bung thing - which way does it come out, into the tank or away from the tank direction? Edit: just seen there is a flange on the bung so it has to come out away from the tank.
