Thanks P!
It seems that a lot of people have problems with fumes or leaking. I hope this helps some of them.
Zero10:
All the info that I have shows that 85.5 and newer are plastic. Take a look at ***********'s parts diagrams for the 944. They show the two tanks and their respective model years.
Mr. Wilk:
I have had no luck finding someone who would weld the tank in the Denver area. If someone can suggest a place, that would be great!
I removed the tank again this morning. A small part of the fiberglass Permatex separated from the steel.
I have come across a possible problem with the steel to plastic tank swap. In my early-style car, there is a crossmember that is integral to the chassis, from which the transaxle is suspended by two mounts (see photo). From the very few diagrams that I have seen, it appears that the later cars use a removable crossmember, from which the transaxle is suspended by a single, central mount. Can someone tell me if this is the case?
The leading edge of the tanks protrude between the crossmember and the trunk floor in both early and late cars. Due to the possible differences in the space available between the crossmember and trunk floor, I'm not sure if the two tanks are interchangeable. It appears that the later plastic tank is thicker at the leading edge than is the steel tank. Any info on this would be graetly appriciated!
Thanks! Neil
