Our new member Nick priced 1.5 inch ID USCG approved fire-retardant fuel-fill hose yesterday. It was HIGH.
Any good sources you guys can recommend?
Here is a discussion on fill hose. Typical THT chest thumping and preening, but there are a few bits of solid info.
http://www.thehulltruth.com/boating-for ... -foot.htmlWith respect to the idea of a hose within a hose; Looks like you'd end up with a max ID of around 7/8ths. A gas pump nozzle would not go in.
Even if it would wedge in, the nozzle would act as a stopper at the fill end, preventing fumes from escaping....almost impossible to get a flow.
You'd also have potential liability concerns in the event of a fuel spill or other mishap.
