My 87 911 with all original fuel lines has a gasoline odor when heaters on and car is in garage after being driven. a brief inspection shows no visible leak. the fuel hose on back of engine more on driver side aged, no leaks, my tech says he will need to check a main hose at front of engine.

any other suggestions to start looking for a leak??

thanks

It's easy to attach a fuel gauge and watch the pressure after shutdown. Then you just have to follow the fuel lines back through the tunnel, or at each end. The front attachment at the fuel tank is known to leak. You might also pull the plugs and see if one of the injectors is leaking.

check around the fuel pump area, for sure.

I am telling you this right now .. replace those fuel lines even if they look good .. even the one that you have to do a partial drop of the ngine to get to .. you are being given a warning most dont . If it still smells like gas afterwards do more investiation but at least you will have piece of mind all fuel lines are new...

thank you for suggestions, also found some info from 2005 that will get me started, meanwhile I have a halon fire extinquisher in car.

Ice is right. Change those lines.

It was when I had to drop the engine to address a crossed S/P thread from the PO (WAY back)....while o9n the ground, we did everything we could get to, TO INCLUDE ALL of the fuel lines occupying the engine bay....found original 1989 lines there....Installed brand new stuff,..and had the old ones reworked to add to the parts' bin.

Years later to discover a fuel leak, underneath-up front (firewall connection area, heading into the tunnel), went ahead and had that reworked (all tubings, but NOT the tunnel hard lines), to include a new fuel pump (removing the ORIGINAL and tucking it away for safe keepings)...be sure to check that front side,...EVERYWHERE!....

Best!

this is on my winter project list.

what I have struggled with is get 'new' porsche' fuel lines or have my existing lines rebuilt.

I think I have seen posts of folks who had a shop rebuild their lines.

thoughts?

I went with factory lines...many have gone both ways, however. (still, my preference was to fo with the Porsche lines).

Now I have my old (original 1989) ones in hand and will probably look into having those rebuit then stored as spare.

Best!

yeah Porsche ones or ones manufactured from a specialty shop will be fine. i think they all know what's at stake ..
Chuck all that extinguisher is good for is putting you out if you catch on fire .. if the car goes it will be well engulfed by the time you figure out what is happening.

I did a youtube video on my fuel lines, rebuilt by Zims. They use original German fuel lines, and crimp them onto the factory hard lines. As close to factory as you can get, at half the cost.

post the vid link , as this is a popular subject i am sure lots of guys would be interested.

THAT is what I would prefer, as to repair paths,......I think I'll give 'em a call and get that ball rolling..thanks for the "refresh", Rusnak.

Best!

Thanks Rusnak,

I exchanged emails with Zims.

and for the front lines
We can repair those as well. Figure about $50.00 per line.

damn after a month of looking finally found the leak. The tech could always smell the fuel leak but after looking over every inch of fuel lines, hot/cold engine we finally found it. Maybe it was cool enough outside so the fuel did not evaporate. any way it was dripping right in the middle of the top of the engine. pelican part to replace $360.

Guess we just have to be patient
