87 CARRERA--Fuel line from filter to rails
 

After chasing a cabin fuel smell I've found the leak. It is the rubber portion of the line from the filter to the fuel rails.

If you look at the schematic there is a small leak in the rubber (right under part # 6 above) closest to the fuel filter

Has anybody spliced the rubber line to repair a leak there? How about replacing rubber with braided steel? I realize this line is under pressure, but DAYUM!!!! Nearly $400 to replace the whole part when only failure is the rubber hose nearest the fuel filter?!?!?

Anybody got a cheaper fix?

You could send your hose to get re-done... I'm not sure of your location but there are a couple of threads that mention a place in Orange County CA (LA area)... "La Mesa (something).."

Or BoxterGT from this boards makes them in braided steel for less than OEM prices.

As SoCal said, take it to a hydrolic shop and have them replace the rubber sections. Probably be around $50.

Thanks SoCal and L8R....good tips.

SoCal...awesome work on yout project!!!!!L

L8R...how's the track car coming along? Any recent pics of the progress?

Dueller, where are you located?

I had Tom Amon of Mobile Works West do mine, he has some tricks ;)

I recall it being about $50 total.

Pretty common problem which only becomes more common as age takes it's toll. Do a search on here. It's been discussed MANY times.

The lines not only leak at the rubber, but also at the swivel. Porsche stopped making this line with swivel fittings and double crimped them instead. The easy home fix is Oetiker crimp clamps and quality 30R7 fuel rated hose. Some have actually done the hose replacement with the line still in the car.

Also be sure to look at number 19. Number 11 is a bit tougher to replace because the hose is pre-formed. A straight length of new hose will most likely kink and steel braided may not allow a tight enough bend radius for good fitment.

Just did mine with some AN- line and "blinge hose clamps" that were readily available at the local" house of horsepower". To make sure of no leaks, when I installed the line I coated the ends with real ureathane windsheild sealer. When that stuff sets an act of God is required to separate.

If you are going to have it rebuilt mark the orientation on the rubber hoses with a sharpie before you take it out.

I repalced it with the $350 part couple of years ago. It isn't that easy of a task. I took the intake off, may have been easier to drop the engine.

But those people have exceptional mechanical abilities unlike any human. ;) :D

I did the DIY replacement KTL talks about and it's easy. Since your line no longer will swivel, I recommend not crimping one end until it is installed. It's tough to get the fitting oriented correctly, and you don't want to pre-load the hose when you install it.

Just remember to slip the crimp over the hose, and in place loose. You can't get the crimp on when the hose/line is installed.:D

Get thee to a local hydraulics company. A few days later and a few bucks and it will look like this

Been there and done that and it cost me $32.00 and a quarter tank of gas.

If that side is leaking then all the hoses are shot and it is dangerous to keep driving.

I removed the intake, but if I had to do it over, I would drop the engine. DROP THE ENGINE OR YOU WILL GO INSANE AND YOUR BACK BE BE CRIPPLED.
