New fuel pump
« on: May 24, 2014, 06:45:09 am »
So it had to happen, don't they all?

New fuel pump went in this am...the old one wasn't cutting out but it had started to refuse to prime after the bike became hot.  Give it 10 mins to cool and it was fine, away it went. But that's a classic sign of a faltering fuel pump, so the stocker had to go.

I bet KTM copped a lot of grief over its crap fuel pumps (as has a few other marques who use the same pump). But then again, I bet the Chinese supplier of such rubbish copped a lot more! And lost a few contracts as well.

So anyway a new pump fitted today...and what did I learn this time around? A few extra cable ties help to firm up the various lines, for when they get pushed back into the tank. Anything to stop the fuel lines getting a kink.

That said, I did the deed, fired the new pump a couple of times to prime, hit the starter and after 3 seconds it fired and ran fine. I let it do it's 15min throttle reset just to see if it stalled etc. it didn't. It ran fine, maybe smoother than previously at idle, so I think the old pump was on its way out for sometime.
After the 15 I shut it down, restarted and it fired up great.

I think that's a job well done. Let's just hope it lasts!
