Gas Smell
I am a new (used) owner of a 88 911 Carrerra. I know some gas smell is normal , however the gas smell I have is intense. It appears there may be some leakage in the front of the engine. What is the easiest way to get in there? It appears I need to take out the aircleaner and maybe the heater fan, and maybe whatever that thingee is the aircleaner connects to. Sorry about my language, I will learn more about this cars terms as I go along. I am very handy and don't have a problem with mechanic work however this is my first Porsche. Any support would be appreciated. Thanks

fuel leaks
welcome to the world of 911's. fuel line leakage on a 3.2 engine are well known. There are two fuel lines prone to leaking in the front of the engine. Access is very difficult without dropping the engine . Search the forum for fuel lines on a 3.2 and you will see pics of the hoses that leak and how some people have repaired them. I did mine while the engine was out. Whatever you do, get the leaks fixed so you don't have a fireball on your hands.

I replaced the line I think you are referring to (page 49, line 19) :
https://techinfo.porsche.com/techinfo/pdf/en/catalogues/E_911_89_KATALOG.pdf Its pretty cheap and you can do it without the dropping the engine but it is a pain. You'll need to remove the heater fan and air box and use a few mirrors to get a good look behind the engine. . Also get your sell a few small stub wrenches and the correct box wrench(17 or 18mm I think) and you'll be fine. Do a search and you'll find only one reason needed to replace the line asap. Its called fire...

A fuel odor on a 3.2 could also be as simple as leaking o-rings on a fuel injector. I have seen this happen on several, along with other makes and models using similar type fuel injectors. Hope you find out what the cause is. Good luck!! Tony.

Tom,
Do you smell gas in the cab or in the engine compartment?

Tom, welcome and since you're new I'll refrain from smart a$$ comments regarding gas smell. Anyway, I had the same problem on my '88 and it turned out to be the short (1 1/2 feet approx) fuel line between the pressure damper and the pressure regulator near the firewall. I could run the engine and feel the fuel leak...didn't run it long like that obviously. Kind of a PITA to replace but IIRC, I just removed the air cleaner box and the AFM, and used mirrors to see what I was doing back there. Have an assortment of open ended wrenches to get at it and make SURE you don't just loosen one of the threaded nuts without counterholding the other side. If it's the large "t shaped" line from the filter to the fuel rails it's a much bigger PITA and many have just rebuilt that line with more flexible connections which makes reinstallation easier.
BTW, I also had/have a leak in the line from the fuel pump (near steering mechanism) and will have to tackle that one as well. In this case I could smell the fuel when driving and it would only leak when running.

When you shut the car off the tube to hose junction dripped fuel into the heater inlet.

 The factory lines at the top of the engine are 930 110 595 05 (Pressure or feed) and 930 110 411 03 (return). I have replacements for these lines in either original black rubber, braided Zinc, or braided Stainless Steel. These are Metric and replace the originals without hassle.  You do not have to drop the motor, but you must cut the orig metal line to remove it. If you have questions, please do not PM me. I am often away on business, so emails are much faster. Cheers, Len@autosportengineering.com
