Fuel line

[2stroke]

The crimp on my fuel line at the accumulator is leaking, and I have searched. I know that Len is the guy to talk to, and I have an e-mail in to him. In the mean time.... Can I cut this crimp off and replace it with some good clamps? Anyone done this? Pictures?

I've not done it, but there are some who have.
If you go with Len, he'll hook you up with good stuff.

If you don't want to wait, or want to try a temp fix with the clamp, dremmel the crimp off.

If you go to cut the SS line, wrap it tight with tape over the cut line and use a 32 teeth per inch new hacksaw.
This helps to keep the pesky braid from going all over and gives you a nice square cut.

I did this when I fit new ss lines using AN fittings (it took a little practice), but I am not a fan of the clamps only b/c I wasn't sure about them long term for pressurized lines. I am sure others have more experience in this.

Jimmy,

Depending on the type of fuel hose you got there, using the correct crimp or ferrule could make a good seal. One place you want to visit is your local hydraulic shop. They could make hoses that are subjected to very high pressure and CIS fuel lines would be peanuts to them. A micro clamps could also be used but they don't look nice like the shop does.

Why are you using those stainless braided line for your CIS? They look nice and pretty. Hope it could stand up against the delivery fuel pressure.

Do you live in a major city/town that has a hose supplier?

If you do then I'd recommend paying them a visit and asking them to make-up a direct replacement unit. This will be the best solution in my opinion as fuel lines are not something to mess with. You want to safely ensure that you can operate the car and that it is not a fire hazard.

I believe that this braided line is the original stock hose?

Not in Porsche 911 CIS engines. Where did you get this information?

I just thought that it was original.

Not original, but this means someone replaced the line with a braided one but did not do too good of a job on the crimp since there is a leak.

This is what I have available for a 78 SC Rear Feed Hose.......



The 180 deg fitting at the accumulator makes this somewhat expensive but its "factory level" and NLA from Porsche.
