Fuel pipes



Do any of you knowledgable types know the answer to this one.

The fuel pipes on my 98 fourtrak 2.8tds need replacing due to corrosion, if i use the flexible rubber type fuel pipes as replacements will it still pass the Mot Unknw

Thanks Frank.

Possibly not, depending on

Possibly not, depending on the tester/station and how familiar they are with the 'traks. If they are like the Sportraks, it's easy enough to replace with some copper pipe and a flaring tool.

BUT I did know a Landy owner who did the same thing with rubber hoses, but ran them 'hidden' in the sills, and therefore not visible to the eye Wink Back of the net..

I agree it is dependant on the knowledge of the tester and easier to use copper. Flexis are acceptable where movement exists or inside the car I believe but something more substantial is required along the chassis rails. Mine are corroded where they nip up over the rear axle and I suspect I might consider using stainless braided hoses there onto the pump to save the complete pipe renewal as I would argue that movement is possible, whether I would get away with it is to be seen, I suspect I would because of their Stainless braided construction and the nearness to the pump, it's an option I would certainly try.

I have used them on Mini's during restoration and they have never been failed to date and most testers know MINI'S. Obviously I only use them at the rear and the front ends not along the entire length of the car, that remains copper. They are used on MGB's from the Pump beneath the rear floor to the piping as well as between the carbs.

been there...

done it, brought the extra tight t - shirt, lol, yes you can use rubber flexible piping, as long as it is proper fuel pipe - which costs a little bit and you need quite a long length of it, and if my memory serves me right you need two types of thickness - 8mm and 6mm bore, cant remember quite, one for feed one for returns, basically flexible is useable as long as its out of harms way, securly fastened and number one - NO leaks, if i was you use the wide fat cable ties that you can by to tie the pipe up along the top of the chassis rail but dont pinch it, i checked ages ago with the mot base about this when i had to do it first, no problems since....

Full of ideas but no time to do them!!

Using copper for the main runs is the best option, with the correct flexible rubber pipe at flexible positions of the vehicle.
Use plastic clips which attach to the chassis to hold the copper pipe from contact with the steel chassis, thus preventing electrolytic reaction. These clips come in two basic sorts, screwed to the chassis, and plug type which fit into pre drilled holes, opt for the screwed type, these are far stronger and more secure. Copper pipe suitable is obtainable as micro bore heating pipe from plumbers merchants, this means an olive can be soldered to each end to act as a flange to clip too.

Both copper, steel, and rubber fuel pipes are legal, but rubber pipe must conform to the legislation. Rubber pipes tend to sag over time and may become snagged or cut if off road use is regularly undertaken.
