I need to extend the fuel line to my eber. I cannot find the right size stuff (even on EBay)
It is 2mmID and 6mmOD. Has anyone any godd contacts for this kind of small bore pipe, one lead I'm exploring is model cars/aircraft which seem to use these sizes.
Any ideas??
 
here?

Do a google on "nylon pressure tubing" - there are many suppliers around.

If it is the tank to pump line you need then go to any decent motor factors and they will have diesel spill way tubing - Stays flexible even after years soaking in diesel.

I think it is important that you get the correct fuel line, rather than something that might do. Go to a commercial vehicle "Lucas" and normally Eberspacher dealer. The fuel line is not that expensive. I would not join it, just buy some long enough.
 
So are you saying Eberspacher and Wabasto and Mikuni etc are selling unsafe equipment? Seems to me they would have had to withdraw all their diesel heaters from sale if that was the case. /forums/images/graemlins/crazy.gif

It is quite easy to fit completely in copper, it can be done. Most installations are in automotive vehicles where the fire situation is less severe.
Fact of the matter is that any plastic or rubber without fire proofing on a boat is a weak point. All fuel lines on a boat should be fire proof.
 
Thanks for 7 rapid responses !!! what is it about eberspachers and this forum? love/hate??

I will try the various suggestions. No I did not plan to join the tube. The point about safety is noted, but also the reponse that an awful lot of instalations will have to be reviewed!!

Size is quite critical so I dont know if the motor applications will fit. Have tried eberbasto so fingers crossed on that.

Many eber stockists are ok if you want a bit of very expensive stainless steel but are not interested in the more mundane bits and pieces.

Thanks for all the advice

[/ QUOTE ]The feed from the tank to the pump is not critical - just so long as it is not too small. I used "spillway" tubing on my installation - 3/16" bore IIRC to fit the inlet of the "tick tick" pump and the "T" in the fuel line.

Before anyone come back and says you need a separate feed from the tank - B.S., some might but even on full throttle I use less than ½gal/hour so there is not much flow to interfere with the "tick tick"

Cliff, I agree that the diameter of the pipe is not critical if the lift from the tank to the pump is no problem. On my own boat I have used copper tubing from the tank to the pump as the pump is below the level in the tank anyway and the pump is therefore self priming. Eberspacher installation instructions insist that 2 mm pipe is used if the pump is mounted above the level though (max head .75 metres) as the volume that the pump delivers in any one stroke is insufficient to prime a line with bigger diameter and airlocks can form. If the pump is mounted above the tank level the diameter of the tube is therefore critical. My own thoughts on safety are that nylon fuel line is fine as supplied by eberspacher themselves, but that it should be well secured away from any hot surface or rotating equipment. for the line from the pump to the heater itself plastic tube is commonly used but eberspacher kits now contain a length of braided rubber fuel line that is supposed to be fed over the nylon line when installed to comply with vehicle (not marine) safety regulations. This also stops it vibrating and protects it from damage.
 
On my installation I used the 2mm nylon tube but passed it through copper tube to above the top of the main tank. The fitting on the tank is a normal compression fitting with the internal flange drilled out to allow the nylon to pass thorugh into the tank. In the event of nylon failure the fuel is held within the copper.
 
Yep, makes sense. On my installation the fuel supply is gravity feed as far as the engine lift pump so up to that point the system is "self priming".

there is a fitter at the local eber dealer who started me on the road to knowing about ebers and the first thing he taught me was bleed the tick tick pump by flashing the terminals and the second thing he said was dont go longer than 1 metre with the black pipe or use anything other than it, reason, the tick tick pump has a good blow but a "bad" suck. the pipe is available on ebay a chap called p hose sells it at reasonable prices.
 
Quite an informed and interesting series of articles.

On my own boat I use copper pipe from the fuel tank to the pump and I slip a continuous piece of clear plastic hose over the top of it with jubilee clips at either end. This is to protect the copper pipe as it winds it's way through the boat.

From the pump to the heater I have the rubbery black stuff.

I stand to be corrected but at one time I think that eberspacier sold a 'marine' add on copper pipe kit in place of the plastic stuff (my old memory thinks it was about £150). It was a requirement for the BWB tests for canal craft at one time.

I know that on the hire boats we always used a copper feed pipe when doing an installation.

Funny that, that is where I got a lot of my info on Ebers, and from Eberspacher technical services themselves. Agree keep the tank to tick tick tube as short as possible. Is 12" short enough or would you recommend even shorter?
It is interesting listening to different "experts" - quite often they come up with totally different ideas on what is "correct"

When we bought our new Eber kit a couple of years ago, the whole fuel feed pipe was in copper with a length of fabric covered rubber pipe to match that you could slip over it as a sheath. I cut some bits off the rubber pipe and only sheathed the copper where its clipped, but sometimes wishes I'd sheathed the lot. Doesn't make any difference to the way it works of course.

I also wish someone had told me how loud the tick tick pump is in practice. Its in the cockpit locker, but I wish I'd put it on the engine bulkhead instead of the galley bulkhead. Its not too bad, but it could have been even quieter if I'd known.
