Best Sealer For Gasoline

Yes, I'm sorry. It is a hard anodize, and is a little less common and not practical to do at home like the more commonly seen anodize. It is somewhat abrasion resistant and has good corrosive resistance as well. I would need to consult my literature for specifics against Ethanol, I'm just going from memory. I'd look at it, I believe. Most any commercial anodizing outfit can do it.
Over the winter I'll tear down the fuel systems and see if I can find someone to do the type III class 2 anodizing. Thanks,
Ed P

Making new parts out of stainless would be my suggestion also.
This would be the equivalent of fabricating a stainless steel carburetor, heat exchanger, and multiport fuel rail. If even possible, it would likely cost more than both motors and the boat.
 
Available at Home Depot.

Where I live we can get premium fuel and it does not contain ethanol. Perhaps switching fuel would be a better solution?
 
Friends that have boats, use premium and avoid the altered fuel as much as possible. Even glass tanks have a short lifespan with oxygenated fuels.

WoW! I forgot about this old thread but I DID solve my ethanol problem. I took the fuel rail and Vapor Separator Tank and machined the integral brass parts out of them so just aluminum remained. I threaded the press fit holes that remained after the brass parts were removed. I brought them to an industrial finishes company and got them hard anodized. When I got them back I made new threaded brass parts to replace the OEM press fit ones. I put it all together and it's been 7 years now with no problems.

Go to any Aircraft Supply. I think it is called PRC. I’ve used it for years and it doesn’t break down. Also used it to seal the hull of a 50 year old aluminum boat. It’s 2 part and has a working time of about 30 min. Treat it like silicone sealant.
