Fuel pipe.. (1 Viewer)

Hiya.
What sort of pipe do you use on a rebuild situation. The original is 10mm steel pipe, which has corroded after 35 years as one would expect. The pipe sections with woven flock over the rubber is in remarkable condition albeit gone hard.
Although I’m a long way off from doing this task.

It seems the rubber pipe made these days is utter crap, with radial/ longitudinal cracks appearing within 12 months.
Over the long length required I’ll of course be using a metal pipe , clipped , with rubber pipe where it used to be.
Options are : steel pipe ( not galvanised as it’ll react with diesel).
Copper, stainless steel.
Just interested what your take is on this.

I ordered the original steel lines for my landcruiser(still available) and replaced them with OEM. 35 years is a pretty decent track record IMO.

Gasoline/Petrol or Diesel? Different rubber hoses in this case. My unit is Diesel, and I simply purchased a bulk amount of quality diesel fuel hose with the same inside diameter and cut the sections that I needed and replaced. I would not use copper, as that also reacts with both petrol and diesel. Best of luck with your project!

A very simple answer - use the genuine stuff. The rubber supplied by Toyota as OEM is very high quality. I recently replaced all the rubber hoses on my fuel system. Toyota sells bulk lengths of hose which often supersedes the original, cut-to-length OEM hose. This applied also to the fuel filler and breather hoses. When you get the supple new rubber you'll realise how hardened the originals are.

Depending on your model, the original steel pipe may still be available. Of course they cost more than bulk pipe but they are bent to the correct shape and painted to make them last. Don't use soft cunifer pipe as it moves around, rubs on things and will often cause problems.

Also, don't be tempted to use jubilee clips (hose clamps) on small diameter hoses (less than maybe 50 mm). They are awful things which encourage deformation of the hose ends. There is a reason Toyota don't use them.

Thanks for those replies.
I’ve managed to source some stainless fuel diesel line. As for the clips those Jubilee clips definitely won’t be using , spring clips like OEM I intend to replace. I’m trying to OEM as much as possible.

If you have the equipment to make smooth bends in stainless pipe, I don't see a problem using it, but in general it's a horrible material to work with and I imagine it will kink very easily.

I would use cupro nickel alloy.
Bends well.
