Hi Everyone,

So far, this forum has been incredibly helpful. I trust that you can offer the same.

First, some background information. I have a 1956 Johnson Seahorse and the original fuel tank which must be manually pressurized. I have removed the fuel cap/delivery assembly from the top of the tank.

1. I have purchased a new gasket to replace the original. The original gasket seemed to either be a rubber or to have also had some form of a sealant. The new gasket that the Johnson dealer sold me is cork. Do I need to use any kind of a gasket sealant on this gasket? If so, what type is appropriate?

2. I've noticed what seem to be some interior deposits of a granular material. Could this really be rust on the interior of a fuel tank that has had oil mixed in with a gasoline? If so, do I need to really worry about it? How do I clean it out?

3. I've noticed some exterior rust and plan to smooth out the surface and paint it with a simple rust-resistant spray paint. The tank is very clearly old. At what point do I say "forget it" and just purchase a new (probably plastic) tank? How much is a tank that is appropriate to this outboard?

Thanks,

Jon

Re: Fuel Tank Questions

a new plastic tank will not work. unless you add a fuel pump, which the motor is not designed for. get as much out of the can as possible, with the assembly off. no sealer needed. rust kill all you can. it will cost you as much as $100 to replace that can.
