I have a ’92 240, and when you fill the tank past 3/4, there is a very strong gas fume in the cabin. Any ideas on what the problem is and how to remedy this?

thanks,
Dana

Welcome to Matthew’s Volvo Site.

Usually it indicates a leak in the tank above the level you quote. As the fuel goes down past the 3/4 mark the smell will disappear because it is no longer leaking.

Petrol running down the sides of the tank will leave a mark which is usually easy to see. Have a good look with a high powered torch.

most of these cars leak on the top of the tank where road dirt accumulates and cause it to rust due to excessive moisture.

Procedure if your going to do it yourself is to drop the tank and use a special gas tank putty to seal it unless the leak happens to be on the seams of the tank. If its seams then it would most likely require a new one.

I have heard that radiator shops can fix gas tanks because it requires similar welding and coatings for repairs as rads.

Ofcourse if your going to work on it yourself.. always keep in mind.. open flames and sparks dont go. Its amazing how many stories you hear of people welding patches to repair gas tanks while the gasoline is still in the tank!!! Also i suggest you work in an open area where the fumes do not overwhelm you.
