Fuel Tank (1997 MK1)
Stop Press !! (May
More serious about the options to solve the fuel smell problem at some MGF
I got my lovely MGF
back after carried out 20k km service in September 2001.
Had complained about the fuel smell at the 1999 made car. Before anybody gets doubts I need to tell that I know very good from what I'm talking about. I have already suffered from another smelling MGF which got at last a new fueltank .
First works at my current cars fuelsystem were already done four month ago at the first service but without solution. So I asked my workshop to change the tank. They didn't, cause they had a new MGR advise on how to deal with that smelling cars. The advise should be rather new from August 2001.
I knew already from older bulletins the advised to:
check the connector to the fuel sender unit. It's prone to fail and melt
the plastic housing
I was found that the screws from that cover were loose at my car. So this would have been the reason why fuel damp got into the car. In the case of loose screws the cover doesn't press the sealing material on the shredder tight to the body shell flange.
I found myself such a crap sealed shredder wrong attached when I disassembled my MGF wreck from 1997 the other year. This shredder wasn't seal to the body shell far down on the LH and RH side. Unfortunately I have no picture of the failed position, but only an overview to the parts and how they look.
Best way to get to the location is from the engine bay. I would recommend to do works outside from the garage and not under hot sun. Dismantle the airfilter box and make loose the other stuff hanging around there. (Brake cables from the plastik clamps etc.)
Can't recall the way of fixture of the brown coloured gaiter, but that is the location of the 15cm long and strong connection hose. The hose I got in the cellar feels very hard. May be it is better for you to buy a new one. My workshop guy talked about dismanteling the hose and make it warm (in hot water?) to get it weaker for re-assembling.
All aroung I guess it is required to loosen the filler pipe in any way (two screws under the filler cap)
App. in the end of 2001 got another bulletin written with the instruction to measure CO2 damp below the car. The brether hole below the tank and near the centre tunnel is the location where to measure. It is said that MGR would change the tank if the concentration is above 100ppm. This only for cars made after August 2001 and if still under warranty terms.

- geknickt geht der Sprit nur tröpfchenweise durch.
Hier wurden die Klemmschellen bereits gegen Schraubschellen
gegen Undichtigkeit und Benzingeruch getauscht
- if it's kinked, than the filling gets difficult
Here the cheap clamps got already changed to worm clamps. It could prevent from fuel smell.
