Been stripping down more of the Classic TVR today and discovered that the plastic fuel pipe from the tank to the pump has degraded so badly it literally shattered into hundreds of pieces when I tried to remove it...

It was just cable tied to the chassis inside the tunnel...

I need to replace said hose...

I had considered just replacing it directly with a length of approved fuel hose...But im not 100% happy with the idea of a flexi rubber hose just cable tied to the chassis...

However, I may have no choice, as access is very difficult to get in and do anything more elaborate...

So, provided I secure the hose well enough that it wont chafe against anything...would it be deemed acceptable? Or should I be looking at an alternative solution?

rubber hose should be fine i think. if you're worried about it wearing through, there's always stainless braid hose i guess (thats what i'm going to use)

I had considered stainless braid..

But after reading a crash report involving a piston helicopter and braided fuel hose...Im not really all too enthusiastic about it now!

But out of interest, where were you looking for the stainless braid?

I am using microbore copper pipe for my fuel u can get it in 8 and 10 mm then use p clips

I think I'd try to get a length of copper in there if possible. I guess it depends on how good your access to the tunnel is though.

I would prefer to keep the lengths of rubber to a minimum and to places where I can see them to check for deterioration...

Cheers

If you use flexi all the way through you car will permanently smell of petrol all the time.....

Its a TVR...its going to smell of glue anyway

Re-the R-22....
Basically due to bad maintinance and dodgy paperwork the retaining P clip for the braided fuel pipe between the fuel pump and carb was not re-fitted properly.

This allowed the Braided hose a small but significant movement that caused the braid to chaffe.... The braid split and punctured the rubber inner hose several times causing the fuel to atomise out of the hole into the engine bay....

Although the cockpit was filled with smoke the pilot managed to land and evacuate before the aircraft was engulfed in flames....

The fuel hose was the correct Robinson part, so was of pretty high quality...

Deffinately an accident worth noting in the kit car community!

I have had a look for the AAIB crash report but no luck...Its out there somewhere!

i used braided - mac#1 supplied it by the metre.

Ive also used 5/16" kunifer on a previous project. Again easily available.

I used 8mm Copper heating pipe. Then I covered it with the 10mm convoluted tubing, and secured with P clips.

Its been in there 3 years, and 4400 miles and is OK so far.

Remember to keep electrical wiring away from the fuel pipes.

I wouldn't use rubber hose, it's likely to need replacing in a short amount of time, I would probably look at using copper or some hardline plastic..

If the car has carbs then plastic fuel pipe will be fine , easy to use and not too expensive. Think Robin Hood/ Lolocost sell it .Fuel hose on the other hand is bulky, dearer and likely to perish quickly.( do a search?) 5/16 Kunifer is fairly easy to use and less likely to kink than microbore copper although more expensive

if possible, I would recommend using solid pipe otherwise get some proper fuel hose, especially if it is braided.

what has happened, on here recently, is that the hose perished but being braided, it was not possible to see that is had perished - search the posts as form where this suttf was purchased.

I have fitted short lengths of braided petrol hose from VWP and 8 years on, it is still fine, well to be more exact, I have not noticed petrol leak nor smell as I have not examined it.
