Fuel Hose Wanted

[MV8]

The fragola hose is the good stuff and will be marked R9 (see pic) for EFI compatible.

I expect the fragola is a lot more expensive.

Any markings on the hose you received?

Here is a photo of the hose. Not sure if it’s fragola as I can’t find it listed.

That's Parker 801 push loc hose. Obviously pressure capable but the only hose they make that is gasoline compatible is FR221. It isn't push loc and is very stiff with a wire braid and made for 500 psi.

 

It could be one of those situations where the 801 hose liner is compatible but they don't want to offer a hose that could be used for automotive or aircraft for liability reasons. Or, it could be that it isn't compatible but you won't know until it breaks down internally and clogs the injectors and pump sock if you have a return, burning up the pump.

 

It is an experiment. I'd replace it with fragola or other R9 labelled push loc, or revert to a common type of push-on fitting and get your hose anywhere.

I agree with MV8 the hose is not the best for gas and will eventually fail. The Fragola hose is made for modern gasoline but is very difficult to push on the fittings. If or when you want to change this line, I would suggest using AN fittings.
