Keeping it clean

So, finally got round to changing the fuel lines. When I took the old ones off (just the HP circuit, the LP circuit looks ok), this is what the lines looked like after 2.5 years and just 7k miles:

When I cut it open, those splits go half way through the pipe:

Now, these are supposed to be R9 standard pipes, the best you can get. However, there are lots of stories online of fake stuff and, in fact, I couldn't find a single place that didn't have a negative story online and there seems to be no way to be sure you're getting the real stuff. So I opted to just get the best quality that I could get from CBS. This is DIN rated, which no-one seems to bother faking and I can always complain to CBS if it falls apart.

I also drained the swirl pot and saw a few tiny rubber particles in the jar. It didn't look horrendous but injector jets are tiny so even small bits could be causing my misfire. Because of these, I've also now added a fuel filter in the HP circuit:

It's clear so I can keep an eye on any dregs.

So, replaced all this, went for a short drive and...misfire gone. But I'm not getting too excited yet until I've done some more miles.

I've got a long weekend to Wales in mid-September with the SKCC - really looking forward to that.
