3.2 engine fuel line rebuild?
 

Any recommendations where I can get my 3.2 engine fuel lines rebuilt? I'm referring to the line that feeds both fuel injector rails, comes to a T in the middle, and starts at the fuel filter.

I've been told these will eventually leak, and before I put the engine into my 914 I'd like to get the line rebuilt. A local shop does them for guys around here, but they are out of supplies and don't know when they will get the materials to do the job back in stock.

Alternative suggestions are welcome too.

Thanks,

Dion

I just used some rubber injector hose and pinch clamps, the injector hose is rated at a higher pressure.

What pinch clamps did you use specifically? I assume there's a brand/style that's desgined for this application...isn't it under pretty high pressure?

I used this style from McMaster-Carr they were the stainless steel just to go over the hose. I think the pump only puts out about 65 lbs The injector hose I used is good to 150 lbs.

Just so I am clear, you cut the rubber bits off the metal lines, and clamped on hi pressure FI hose, correct?

Yes, be careful cutting off the old metal clamp so you don't damage the steel line, I think I used a small cutoff wheel in a die grinder. Fit all the new lines first then clamp them down because they have to be turned a certain way.

Got it. Thanks Craig.

One more question, any special tools needed for that style clamp? Is that better than the common screw clamp?

Dion

You can use a good quality screw clamp but I used the pinch type because it looked cleaner, I just used a pair of side cutters to pinch it down.

Great. Thanks again!

Dion

I just checked my hoses and what I used was 3/8" or 9.5mm Goodyear FI hose and the #157 pinch clamp. McMaster has them for $5.00 for 25

If you have a cheapie extra side or end nippers, run the blades cutting edges over the grinder and make them sort of dull, then you don't have to worry about cutting the new clamps with you nippers. Tony.

Great idea on the nippers, and thanks again for the info. I guess I do have one more question: do you put bubble flares in the metal lines as well?

Thanks,

Dion

The flares should already be there.

You may want to try this alternative.

I sent them two old fuel lines and they rebuilt them both very cheaply.

Anyone have a solution for the 2" pre-formed elbow? Is there room to do a gradual bend with normal hose? I got the others made up by a local mechanic who had the correct hose and crimp ferrules. Thanks, Ken

I finally got around to calling these guys today (Amazon Hose), and the sales person I talked to (Matt) told me that they do NOT rebuild fuel lines and that all of the people on this forum must be mistaken because they only rebuild air conditioning hoses, oil hoses, etc. I told him we had pictures to prove it, and he flatly denied that they have ever rebuilt any Porsche fuel lines. I tried to describe it a number of different ways as nicely as I could, and he just kept giving me road blocks.:mad:

So much for that option. I have the hose and clamps and will probably just make them myself this weekend.

Dion

That's wild.:confused:

I actually think it may have been Matt that helped me. They even checked the hose they use to make sure Ethanol would not be an issue...

They must have been scared off by liability issues....

Sorry for the dead end.

No worries, and I appreciate the help. If they were scared off, Matt did a nice job of making it sound like they have NEVER rebuilt fuel lines - fuel injection, Porsche, braided lines with a T connector, nothing.

I ordered everything I need from McMaster-Carr to build them myself, including 15 ft of line, the tools and 360 degree stainless clamps for $50. Not as slick as braided, but I hope to never touch them again. :)

You really cant see much in there anyhow

Exactly! And mine is in a 914, so your lucky to even see the engine without climbing into the opening......
