I am looking to repair my fuel lines leading from the engine bay to the fuel rail, including the return line. I would like to repair the section of the line running over the motor as it is damaged from heat, rather than replace the entire line. I have read around, but dont fully understand how this is done.

Any help is appreciated.

the replacement lines are available from Paragon- I'm pretty sure they carry them, but for the life of me I cant remember thier website. They are also available from the dealer ($$$.$$)
You mean the rubber lines or the hardline?

The rubber lines...

All you need to do is use a cutting wheel tool and cut the compression fittings off of the hardline right behind the brrake booster (tight fit). Then go to the auto parts store and buy some fuel line (3/8" I believe) and clamp it onto the hardline. The hard line is flared at the compression fitting. This should cost you $5-7 bucks or less.

Thanks Jason, if you use standard rubber hose, make sure to leave enough hose length on the hardlines to double clamp them. It IS a fuel line going over intake/exhaust manifolds..

I still cant find Paragon's website. sheesh..

How about the end that leads to the fuel rail ?

Jason-85944

The hose that goes to the fuel line comes off of the Dampner, this hose was recalled by PCNA. Call your local dealer and give your VIN. Mine was replaced 2 years ago....N/C. If it has already been replaced, you will need to buy a new one from the dealer. That should be the only hose that directly leads to the fuel rail on a 924S. The regulator at the back of the rail directly connects to the rail.

Hope this helps you out.

ike,

Are you looking for the(2) one supply/one return rubber lines which come up from the inner fender and go to the FPR, or the stubby line that runs from the dampner to the rail itself? If looking for the supply/return lines, your best bet is to buy a complete line with the compression fittings--Lindsey and 'lister Pauerman carry these. You should also replace the stubby line as well. Replacement is fairly easy--I would NOT use a dremel, but rather a small manual pipe cutter(2 bucks at most hardware stores). I did this switch, along with FPR/Dampner/injectors about a year ago--if you need some direction, let me know, I can provide step-by step.

Just an FYI Eric. The lines to the Dampner and from the FPR don't come from the passenger fender like on the 944. They run up into the engine bay on the drivers side behind the brake booster. I have done this repair before. There is no way to get a pipe cutter in this tight space. You would not want to cut the hard line anyway because you would cut off the flared end. BTW...the fuel delivery line only has about 80psi of pressure. The way that the end of the hard line is flared in combination with the proper fuel line clamp is more than sufficient to hold this type of pressure.

Allright, im still confused on what to do at this connection....

Jason-85944

My car did not have a fitting like that, just a piece of hose pushed on with a fuel line clamp. I've not seen one with the metal like that before.

Cut it off at the swedged fitting. The attach with a clamp just like on the other side.

Chris, got you covered...

Why Porsche decided to keep the routing of the fuel lines over the intake manifold is completley beyond me for the 924S, i dont see why they just didnt change it to over the exhaust like on the 944's.

ike229

Whats the "swedged" fitting? and is one hose clamp going to hold the pressure?

M758

That is part that is not the nuts.

Yes a hose clamp will hold. Cut edge off the outside of the fitting off and it will open up allowing you to slip the hose off. Best way to cut is parallel to the length of the hose.
