daverclasper Posted July 27, 2023 Report Share Posted July 27, 2023 Hi. Vitesse is outside all year, so will be some damp conditions. There is some rusting/pitting of fuel line in the engine bay. Thinking that removing/treating rust to stop it getting worse, though would feel more confident if had an idea of roughly how thick the metal is?. For example, if say about 1mm, should be ok, 1.5 mm, even better. Thanks Dave Link to comment Share on other sites More sharing options...
johny Posted July 27, 2023 Report Share Posted July 27, 2023 Not time to upgrade to copper Dave? A poor condition fuel pipe would be a MOT fail and is pretty easy to change... Link to comment Share on other sites More sharing options...

Bundy tubing then wall thickness will be about 1/32'' (ish). At less than 1mm even a fairly innocuous looking bit of pitting can easily have a pinhole at the bottom.

Wagger Posted July 28, 2023 Report Share Posted July 28, 2023 Fit copper pipe, clip it up and forget about rust. It will go green if left and protect itself. Don't allow it to 'Wag or wobble', however, as it work hardens and can fracture. Link to comment Share on other sites More sharing options...
johny Posted July 28, 2023 Report Share Posted July 28, 2023 Must admit doesnt look original but as you say lasts and there doesnt seem to be any other material easily available... Link to comment Share on other sites More sharing options...
trigolf Posted July 28, 2023 Report Share Posted July 28, 2023 Rather than copper, you could use Kunifer ( Cupro Nickel) pipe, which does'nt suffer from work hardening like copper. Link to comment Share on other sites More sharing options...
johny Posted July 28, 2023 Report Share Posted July 28, 2023 Is it silver coloured like original and can you get it in rolls as I find 'kits' a rip off? Link to comment Share on other sites More sharing options...
trigolf Posted July 28, 2023 Report Share Posted July 28, 2023 It's a paler colour than copper and you can get it in roll form. 1 Link to comment Share on other sites More sharing options...

daverclasper Posted July 28, 2023 Author Report Share Posted July 28, 2023 (edited) Thanks, useful info. The pipe area across the front of the engine, is held by a clip that is fastened by a bolt through, (I think ?) ,the water pump housing and into block. Do you think the seal of housing to block would be undisturbed and therefore ok if I removed this bolt and refitted it?

Iain T Posted July 28, 2023 Report Share Posted July 28, 2023 No it's fine, done that when I fitted a rubber lined P clip. I'm not partial to chaffing😬 Iain Link to comment Share on other sites More sharing options...

I thought it would be, as has not been disturbed since I bought the car 10 years ago, so probably, well bonded together, if you get my drift Link to comment Share on other sites More sharing options...
daverclasper Posted July 31, 2023 Author Report Share Posted July 31, 2023 Hi. I am going down the copper route. Are the fittings into the pump a small olive/compression type joint please Link to comment Share on other sites More sharing options...
Colin Lindsay Posted July 31, 2023 Report Share Posted July 31, 2023 Yes, olive fitted round pipe then tightened by the screw fitting. Make sure you get the proper Imperial size, it seals better than a close metric fitting, plus there are different versions of olive, but I've always found the plain type best. (Some have a band in the centre, no idea why as I've found them they are harder to fit / seal.) Link to comment Share on other sites More sharing options...
daverclasper Posted July 31, 2023 Author Report Share Posted July 31, 2023 Thanks Colin. Intending to buy from Paddocks. So, Mines a Mk1 2Litre Vitesse, that has 1/4" pipe throughout (I understand the Mk2 has 5/16" from pump to carbs?). Going by their website, I can buy 1/4" pipe and also the T piece section that goes to the carbs, though this appears a generic part. if this is the 5/16" size, do you think I can get my existing 1/4" hose on with a bit of persuasion?

Colin Lindsay Posted July 31, 2023 Report Share Posted July 31, 2023 I'd rather stretch a smaller hose than have a loose large one on a small pipe, just be careful of the dreaded rubber slivers. Vaseline also helps the narrower pipe go on more easily, but being a fuel line just make sure it can't slip off again. Link to comment Share on other sites More sharing options...
PeteH Posted July 31, 2023 Report Share Posted July 31, 2023 Hi I ran 8mm O/D "copper" when I had the chassis stripped, there is an awakward section under the rear tub where there is a hose joint on the original, and one under the front tub too. I joined it with an 8mm "enots" fitting`s, and ran all the clips in protective plastic conduit. The hose section(s) under the body are not a very good example of "good engineering" Pete.

daverclasper Posted July 31, 2023 Author Report Share Posted July 31, 2023 (edited) Thanks. Have ordered the parts. Hopefully should be ok. Maybe use my usual method of dipping the end of hose in boiled water to soften and vaseline Edited July 31, 2023 by daverclasper Link to comment Share on other sites More sharing options...
68vitesse Posted August 1, 2023 Report Share Posted August 1, 2023 Had trouble with the compression fitting sealing on the outlet from the petrol pump, 2L Mk1 Vitesse, so fitted a small O ring pump side off olive which solved the issue. Think the larger bore petrol pipe on M2 Vitesse is only between tank and pump but I'm often wrong. Regards Paul. Link to comment Share on other sites More sharing options...
Peter Truman Posted August 1, 2023 Report Share Posted August 1, 2023 had the same issue of a leaking olive but I soldered the olive to the pipe this stopped the weep/leak. Link to comment Share on other sites More sharing options...
PeteH Posted August 1, 2023 Report Share Posted August 1, 2023 Weepy olives, are mostly down to them not being annealed properly, if at all, I go for copper ones if I can get them, or dangle them on a wire in the gas ring until red and plunge into water or oil. A lot of outlets will sell 8mm olives for 5/16 too. Enough difference to allow leakage due to the tolerances. Pete Link to comment Share on other sites More sharing options...
daverclasper Posted August 4, 2023 Author Report Share Posted August 4, 2023 HI. Have fitted new pipe and T piece. Not started car yet to check for leaks. One thing. I removed the bolt (mentioned previously) which holds the pump housing and petrol pipe P clip. The bolt was wet with coolent and the hole weeping slightly. I wasn't expecting this, is it a problem? Thanks, Dave Link to comment Share on other sites More sharing options...
johny Posted August 4, 2023 Report Share Posted August 4, 2023 Keep an eye on the area Dave and your coolant level but probably as you undid the bolt the joint, being only held by 2 other fixings. opened slightly so coolant was able to pass from a water passage to the bolt and its hole....

daverclasper Posted August 9, 2023 Author Report Share Posted August 9, 2023 Thanks folks. All good now One thing. After fitting the new pipe work, though not connected to carbs yet as I wanted to run some fuel through to clear any debris that may be in the new pipes. I turned on the fuel tap in the boot, that I had previously fitted. In the past, I have had to crank, or operate pump manually to get fuel through as I remember?. Straightaway, fuel started to flow out of carb ends of pipe. This has never happened before as I remember?. Is this ok Ta Link to comment Share on other sites More sharing options...

Thanks, Dave Smear the bolt with Copper Ease/Grease to stop it seizing, I always lube the pump and Thermostat cover bolts this way to stop future seizing Link to comment Share on other sites More sharing options...
