Thread: Fuel hose advice - please :)

I replaced and rerouted the entire fuel system on my TD5 with fuel injection hose and hose clamps after getting tired of repairing damage to the hard nylon lines in the rear wheel arch.

I've done about 1000km since doing it with no issues

The Tdi doesn't run high pressure so regular fuel lines are fine. Been running mine with the transfer pump now for 5 years.

If you do any remote travel I would consider keeping the transfer pump in-case the pollack valve fails.

Fuel injection hose is rated to 200PSI so is fine for any fuel injection.
I fitted EFI to a 77 RRC and routed fuel injection hose from the tank to the engine bay with no problems. If you are concerned about stone damage add some convoluted cover. Jaycar do two types a spiral one and the split type.

As others have said - the lines aren't pressurised so you'll be fine. My county had a 200tdi conversion when I bought it, and that was all done with rubber hose and no problems.

I've been running nylon truck brake tube for the bulk of the fuel lines since I did the Isuzu conversion. Have done around 50K km's since with no problems. Any really likely rub points I've just sleeved with corrugated tube or a bit of rubber hose.
The end connections to tank and engine are done via rubber hose (slid over the outside of the nylon) and normal hose clamps.
I keep a metre of rubber fuel hose and some clamps in my spares box in case I do need to do any field repairs.
The roll of truck brake hose cost about $70 from memory, but I only used about 1/3 of it so have enough left for another couple of projects

This forum is quick on the draw

Good to hear hose clamps and 'rubber' will do the job, seems like it would be more convenient out bush if you need to replace a hose or swap connections around.

Hi Sirocco, I see you have brought in a 90 from the UK - like me .. welcome to Melbourne.

I have thought a fair bit about this, I've been meaning to sort out the extra tank since I imported it two years ago! The tanks been sitting on the shelf whilst I've been busy with other things.

If the transfer pump fails on your set up, what would you do? I guess syphon out of one and pour back into the other right?

The reason I want to go with a pollak is because I beleive if they fail they fail in one position or the other. With the pollack valve under the drivers seat I could easily swap the send/return lines over manually (+1 for rubber hose and clamps) and use all my fuel without much delay. But yes if the pollak turns out to be flimsy I will probably switch it to transfer pump.
