Has anyone used any particular type of replacement fuel pipes for bio diesel.

I replaced all my fuel pipes 3 years ago, but I'm noticing slight deterioration of the rubber pipe due to the bio, I intend to do them again, but don't much fancy £14.99 a meter for the genuine bio compatible pipe.

As it stands at the minute my options are, 8mm copper pipe, cheap but too much fiddling and still need rubber at each end or polyurethane pipe, cheap, very easy to run and will connect up at each end with no joints.

I could also just go back to diesel as I only use it once a week for playing out, so don't use as much as a D/D, but I don't like the price at the pumps either Shocked

I've done it all front to back in polyurathane and I've made it up on push fit fittings, so if I ever have to do it again it's a two minute job to unplug the pipes and replace them, because getting to the fitting on top of the tank is a right PITA, would have been easier dropping the tank, but it can be done if you don't mind ragging the skin off your arms Rolling Eyes

as a bonus I can see the fuel in the pipes, so if I get air in I'll spot it.

I have read that normal seals and pipe doesn't last at all with bio. When my 2.8 pump started leaking I inquired about bio seals. They were much more expensive, but at the time I was spending £320 on fuel to get to work and back, so bio/veg looked like a good option. My limiting factor was availability of bio in Norwich. I eventually went for normal seals and diesel, and since then moved and now working from home so its all a moot point.

Bio is OK, but it has it's drawbacks, besides attacking rubber, it holds more moisture, I've had my water seperator light on twice over 1500 miles, never ever had that with diesel, neoprene seals are supposed to be good for bio, it's not saving me much as it's not a D/D, so I'll most likely go back to diesel anyway.
