Has anyone heard about the make up of our gas (as of this year)which will cause the plastic and seals to deteriorate over time in our gas tanks? Will we need to switch to metal gas tanks?
Since we all have metal tanks in our cars... it's not a big deal... but, for our water craft? Doug, have you heard? Anyone?

It is my understanding this risk only applies to fiberglass tanks. It is the ethanol that is causing the fiberglass to deteriorate and it is fouling fuel filters, injectors, etc...

I think the gas tank on my truck is plastic.

Gas tanks in automobiles have most always been metal because of the road hazard factor and gas tanks in boats have most always been aluminum or plastic because of the rust factor. Plastic tanks are now showing up in automobiles, but they are shielded from the road hazards with metal shields. For now there shouldn't be any problems with the fuel mixtures in the existing tanks.

The tank in my 99 F250 was plastic, 92 Jeep Wrangler is plastic & my 99 suburban is also plastic. Not 100% sure about my '88 Chevy 1500, but I believe it's plastic as well.

I am certain that my tank on my 86 MC is Plastic. What would be an example of a gas burning machine that has a fiberglass tank... since the new gas could effect it? :confused:

Large, older boats - Bertrams, Carvers, etc. have fiberglass tanks (and maybe some others vehicles - don't know). Supposedly, the boats have to be ripped up to to cut out the tanks (and then find/install metal/plastic). Really expensive process...
