K-Jet fuel pipe problems

pimpdriver · 28-04-08, 10:17 AM

Hello,

Now I know it isn't a VW, but it is running KE-JET and I have a bit of a problem......

Noticed a bit of moisture on the joint of the offending braided pipe at the metering head end.

Touched it, and it snapped in my hand.

I have managed to get a decent seal on the hard pipe end, see photo:

But the seal onto the braided line is crap, as the fuel tracks up the braided outer.

I have tried wrapping it with PTFE tape, but it still leaks (the pipe and clips are proper fuel ones).

Can I cut the braided pipe at the other end:

and put a length of fuel pipe between the two?

Bugger and arse are the words that come to mind, some guy was supposed to be sending me some replacement pipes (so I didn't buy a spare engine off ebay that had all the pipes with it), but typical, he has disappeared off the face of the earth.

Any ideas?

Steve

If you take off the whole pipe, could you use copper pipe, and flare the ends with a brake pipe flaring tool ?

Possibly. Looking for a quick (and safe!) fix, got to go back to work tomorrow.

Don't want to take off the whole pipe, as it joins to the injectors (under the inlet manifold)

There isn't really a safe bodge on this. Keep an eye on ebay. These metering heads and lines turn up quite often on there.

Another idea.

Carefully cut all of the flexible pipe off at both ends so that all you are left with are the solid pipes at each end. (junior hacksaw blade and then rinse everything with white spirit). Then clean them up emery cloth to remove any pitting or uneven surfaces and fit a piece of rubber fuel hose similar to how you've done your original repair using hose clips.
I did something similar to an old Porsche 924 on the hose that runs from the fuel pump up to the injectors. It had gone rusty up over the rear axle somewhere and was spraying fuel out. I didn't have time to either go and get a new pipe, or fit one, so I just cut off all the flexy hose and fitted a new piece of rubber pipe over the solid ends. Due to the pressure, I used 2 jubilee clips at each end as a precaution. I did the same sort of thing on the autobox oil cooler pipe on a Fiat 132 as well. It didn't leak again.

** Edit - If you can't find a new one, maybe these people can make one up for you.
