Sprint fuel lines.

[Bumpa]

The Elan had a plastic fuel line from new, back in the sixties. When I rebuilt mine I used PTFE (Teflon) pipe as it is semi rigid but flexible, can be used with brass olives if necessary, and from my years in lab work I knew it was almost completely unaffected by every chemical. One of the most inert substances commonly available. I got the pipe from eBay.

Interesting reading everyone's comments. I don't know how I can flare the ends of the 8mm....

The fuel lines don't need to be flared, its all low pressure so won't come off if you use the correct sized rubber hose sections and clips.

And before anyone says anything, I have checked the originals on RUK and NWL so that's one of the first and one of the last and neither have flared fuel lines. I seem to recall that both cars simply had the fuel lines pushed onto the fuel pump as well.

All the shells were the same so you should have some holes for clips. I can show you the rear section and the centre section but the front section's probably going to be different on a OHV car as the fuel pump is the opposite side to a slant.

Bresco do the clips, hose clips and Advanced Fluid Solutions do length of the correct fuel hose as well.

I have all my fuel lines and brake lines, tandem and single if people need photos or measurements.

Oh and copper is illegal to use for brake and fuel here in Aus.

Yes, you have some strange laws down there, bike handlebars over 700mm wide are also illegal!

There doesn't seem to be much standardizing (or logic) behind which side the fuel line runs on and most shells seem to have clip holes on both sides. My Toledo with (originally) LHS fuel pump has its pipe on the RHS of the car and my 1850 shell with RHS fuel pump has its pipe on the LHS, but the Sprint shell had both pump and pipe on the RHS.

Since I am more concerned with safety and good engineering practice than originality, I tend to run new pipes along the RHS of the car, ie as far from the exhaust as possible!

The original fuel lines did not have flared ends, the fuel rail and carbs have no flares either, the flares are on the fuel pump.

I would suspect its because copper pipes tend to crack under vibration. You dont get so much of this in a domestic heating
environment whereas you do in a few places where the fuel pipe goes...

Steel was OE....for a reason.

i would always use steel over copper, or at least use the plastic fuel line as used on moderns. either way make sure it is well clipped up.
