Fuel Odor


Recommended Posts

Do you only smell it on startup or all the time? There is a chance it is your fuel cap if it is at startup.

I had a similar issue and the issue revolved around the two fuel lines (cloth coated leading from the tank ventilation box (small square plastic box between the tank and fill pipe). These were supersaturated with gas and when I replaced them - the smell disappeared. I also replaced the rubber tank pipe sleeve that fits between the fuel door and the interior of the luggage compartment - it also connects to an overflow drain on the bottom. That was easiest replaced by removing the fill pipe and fitting it in from the fender well. There is also a round tension ring at the top that holds it in place.

1989 Targa

I find my car smelling up the garage with a fuel odor. I don't see anything leaking. Is there an issue with this model and fuel lines?

I would like to garage it but not as it is!

Check that you have crush washers on both ends of the fuel filter.

Fuellines and the Ventlines to age and some do shrink and crack other swell and develope "bubbels".

US Fuel is a strange mixture. The 3,2 Fuel System has two steel tubes runing trough the middletunnel and high pressure hoses with press on fittings. Now in the 80´s the manufactorer from the rubber fuel lines garantied they will survive at least 9 years even under US Conditions. Today a great number of cars still have the factory rubber lines, some cars got new factory lines and some cars got aftermarked rubber lines wich where made from more affordabele Materiel wich will nocz last 9 years some are even with rubber from the OEM but a lower Quality.

The Ventlines are made from a special Material and somtime got replaced by simple PVC Clear Hoses.

And like mentioned from Skip the vent system from the feuel tablshould be checked yet 87on cars have a other filler neck system with a plastic housing under the wing flap so things look different.

The most important fuellines are the high pressure fuellines in the enginebay especialy the one runing between the fuelrails connecting them and routet behind the Fan shroud, those get hard and shrink developing small ceacks somtimes you can smell them inside far before thy let off sometimes those rubberlines will just snap filling the enginebay with fuel.

Mostly the engine will starve due missing fuelpressure, people stop and call the road assistance but sometimes it is better to have a fire extengguisher in the car a now forbiden Halon Extenguisher will kill the fire witoz to much resudies in the engine bay a modern powder unit will stop the fire but adds more work to fix up the enginebay.
