Fuel line - how much?

Post by Penfold13 » Sat Oct 17, 2020 2:54 pm

Hello,

The horror stories on here have promoted me to replace my fuel line before I get the car finished and back on the road. Looking at getting R10 based on the recommendations here, but it’s not cheap so I want to get enough, not too much! How much should I get?

Also thinking of a cheap in line filter based on issues with another car. Any advice on anything I should get or just anything will do?

Thanks all,
Chris

A metre should be enough? I think it’s about 100mm/4” for the bit by the tank (that people forget about :lol: ); the rest you can figure out with a piece of string - literally.

Don’t forget to use proper fuel line clips - whether screw type (with the 2 ears) or the original spring type.

First you should read the "Death of a Scimitar" thread, which will tell you all about the subject and the counterfeit hose that abounds. That's why I only sell Cohline... http://ajlelectronics.co.uk/epages/8323 ... Fuel_hoses

Inline filters are always a good idea IF INSTALLED SAFELY. Don't even think of fitting one in the engine bay, unless it is a full metal type and even then I would be reluctant. The ideal position is where the factory put them on the 6b onwards, which is above the rear axle.

I did assume that research had already been done based on the “not cheap” thread - the good stuff isn’t in comparison to the stuff that falls to bits within months.

Even 5 metres is cheaper than a fire extinguisher...

Agreed - a metre of Cohline 2240, 8mm (nominal inside diameter) is plenty, including the short hose from the petrol tank.

Thanks for the responses.

I think I need to replace everything from the front to the rear as it appears to be a transparent plastic fuel line in place currently. Doesn’t look right at all to me, so I was thinking ~5m to cover this.

In terms of the comment on the fuel filter, fair point. My other car uses a gravity feed from the fuel tank which is in the engine bay to the carb (simple, but slightly worrying design!). What would you do for a filter on that?

No, that is not how it is done and will cost far too much into the bargain! The majority of the fuel line is rigid, nylon from the factory but you can use Kunifer pipe which will fit the original clips on the chassis. The Cohline is only required from tank to rigid, rigid to fuel pump and fuel pump to carburettor.

If you have no choice, then a metal filter and use Loctite on the body threads if not a solid throwaway type.

Transparent fuel line doesn’t sound right - normally coloured (black normally but I’ve seen red).

My nylon fuel pipe is white-ish.
On a Coupé, no idea if it's original but unlikely to be, on my car :mrgreen:

Ordered 2m from you AJL, thank you!

It might be white-ish, just seemed to transparent when I was under the car is the gloom. I should probably have had another look before I ordered the line, but I went with it before I saw the new posts. I’ll try and take a another closer look in the next few days.
