Jeff
I think they use the gas tank as a heat sink which raises the temp of the fuel which makes the FI more efficient as well as the AC line which is cooled. My P4 does the same thing with a plumbing arangement that pulls heat from the water tubing and adds heat to the fuel. JRV? Do I have this right?

Thanks JRV, I totally agree-but-I must take it to a repair shop now because I accidentally ripped off the nipples for the charcoal cannister hoses. The braided hose stuff is the pits to remove. Today I will cut the two hoses from the upper fixture and just use what ever is available from the auto parts store. I have a very skilled welder friend who may fix my tank for me, I'll butter him up tomorrow and spring this on him.
Why did they route the air conditioning pumbing through the gas tank? Does the fuel act as "coolant" for the system? And too bad this "little fact" does not show up in the shop manual or parts manual. Forshame!
I think your right about the cause of the hole being an aftermarket sound system. |

I did see a screw hole in a tank once from a Stereo Instalation, where they used long sheetrock screws.
A "Gas Tank Repair Epoxy" is availble to repair small holes like you refer to. Just make sure it's the type of epoxy specifically for gas tanks and you'll be able to repair the leak pronto.
I think I would install a screw in the hole with epoxy on it to minimize the actual leak, and then epoxy over the entire area to insure the best seal & repair.
The cloth braided hose is availible at any German Car parts sales place by the meter in all different sizes.
such as..www.performanceproduct.com or www.pelicanparts.com |

Well, I pulled down the right side tank and it was NOT a fun job. Those cloth-like braided hoses do not come off easy if at all. You'll probably have to cut them off and buy new stuff. To get the hoses that go to and from the charcoal cannister off I twisted and pulled and suddenly "POP" off they came. Then the awful truth hit me as I saw it tore off the tank spout instead of coming off. Also, something not in the manuals is the air conditioning pump plumbs through the tank so you'll loose everything there. I must say I invented some new cuss words getting that tank out. The leak is under one of the isolator foam strips, and it looks like a self-tapping screw may have been there at one time. I will employ a similar method to fix it I think. Now where do I get that braided hose at? Or can I use some domestic stuff-although it won't be "correct"? Any advice is appreciated. |
