Safe to use LPG polypipe for fuel injection?

[rcx106]

As an easier alternative to copper, was thinking of using Faro polypipe, designed for use in LPG, as the main fuel injection feed on my Vitara. What do we think?

I've found nylon pipe that is pressure rated and also fuel resistent, but no fittings! Was going to use the LPG fittings, but they are designed for Faro brand tube which isn't nylon but some other semi rigid material.

Will the nylon tube be good for bridging the gap between the chassis and the engine? Remembering that the engine is soft mounted so that bit of hose would be moving a lot.

Stevie, I've just seen this video, it's pretty good because it gives you the standard that a tube must have to be fuel rated.

It shows the guy using regular hose tail fittings, heating the tube and pushing on. Super neat, easy, and easy to get fittings. Is this like the OEM way you mentioned?

I know about using Ferrules (inserts) that go into the tube when doing a compression fitting, god save anyone that doesn't use them, the joint won't hold.

So diesel is low pressure? My manual says that the EFI pressure on my Vitara is only 30 psi or so.

I'm going to use compression fittings on the main commie, and tails on the return and vent.

Thanks Stevie!
