diesel leak corroded fuel pipe

[citsncycles]

Hadn't realised veg oil also attacked copper - I have 1 set of OE pipes for Timex, but may have to sort something for Fred. Both have Bosch pumps and I have run Timex on anything up to a 50/50 mix when I can get it cheap enough.

As for nylon pipes, Citroen used it for the fuel line on 2CV's etc from at least the early 70's.

Rob Moss posted on Facebook yesterday that he is looking into getting fuel pipe made up.

I think OE steel pipes are sttill available so you may want to get another set in stock! The main reason for me using the heating pipe was that was what I had lying around. The price of copper these days OE ones probably work out cheaper!
Yes, Citroen used nylon pipes, but to reiterate, there are different grades of nylon with differeing resistance to attack, and back then no one had to worry about the corrosive/aggressive characteristics of Ethanol.... Having said that, I haven't heard of any specific problems with old nylon Citroen pipe and modern fuel, and I'd be quite happy to try the nylon pipes linked to earlier, if I didn't already have a couple of rolls of copper in the shed!

Same here - I'm pretty sure the last OE set I fitted cost me under £20 (cheaper than copper), but since then I've just used up what's left on the rolls of copper in the shed. (Better check that hasn't been pinched too...)

My new purchase has leaky pipes. I have got some copper kicking around, but the ethanol concern seems a valid one. If I was to buy the nylon pipe, how much would I need?

[mat_fenwick]

Normal diesel shouldn't contain ethanol, but there is a diesel/ethanol blend in use in some places. I wouldn't worry if you already have suitable pipe.

[Dollywobbler]

I thought even normal diesel now had 5%? EU directive for 2014. By 2020, it should all be 10%. Not good news.

2m of for each pipe would be ample with the return and the delivery pipes being a different diameter IIRC.

As I understand it, that's true for petrol but diesel is being blended with 5% (or more) biodiesel. E-Diesel is still in the development phase AFAIK, unless you're more up to date than I am. Pipe diameters are 8 and 10 mm OD.

[Dollywobbler]

If I go the copper route, I've only got 10mm. Problem?

[mat_fenwick]

The 8 mm pipe might stretch with heat, but it'll not do it any good in the long term. I'd get some more nylon for the smaller diameter pipe, as it's probably significantly cheaper than copper!

[Dollywobbler]

Might just be easier to go all-nylon. The copper is coiled from when it was removed from the house, so getting it vaguely straight again will be fun...

The UK is now all ULS (Ultra Low Sulphur) Diesel though including Red Diesel from last year.

So what's the effect of ULS fuel on engines like ours?

Aye, but that's a separate can of worms! It's supposed to meet the same lubricity standards without the sulphur but with a different additive but I've heard anecdotal stories of problems. But problems occurring after a change in fuel (which may have happened anyway) are more likely to be blamed on the fuel...

Here's a bit more info on the biodiesel in dino diesel that was mentioned - in a nutshell the plan was to have between 5 and 7% biodiesel content by 2013/14. The document I was looking at is 2 years old though and there may be revised targets now.

Strangely enough I was on a Land Rover Forum last night and discovered that many LR owners now tip two stroke oil in the fuel tanks when topping up to compensate for the lack of sulphur and most appear to believe there engines run smoother and quieter as a consequence.

The opening comment on the LR forum:

"Been using 2 stroke oil in my 200Tdi for a week now, got to say it runs sooooo much smoother, sounds like it's had a good service not as rattily"
