PieEater3142 Posted February 13, 2012 Share Posted February 13, 2012 I am fitting an Eberspacher diesel heater to my project and I am trying to figure out which T piece I need to break into the fuel line. Does anyone know what the diameter of the fuel line is for a 200tdi Defender engine? Also I have braided fuel lines but I don't believe this should make a difference. Thanks in advance, James Quote Link to comment Share on other sites More sharing options...
Orgasmic Farmer Posted February 13, 2012 Share Posted February 13, 2012 Someone can confirm but I think it is probably 8mm flow and 6mm return (based on visual measurement of the ones on my TD version). Quote Link to comment Share on other sites More sharing options...
PieEater3142 Posted February 13, 2012 Author Share Posted February 13, 2012 OK, i have braded hose that i install and they look the same size. slightly worried now. But thanks for the answer Quote Link to comment Share on other sites More sharing options...
PieEater3142 Posted February 13, 2012 Author Share Posted February 13, 2012 I'm working away from the vehicle for the week but does anyone else have braided fuel hose that can tell me what the likely size T piece I need is? The tank is a Disco 200tdi I believe, at least that's the sender in it and it all goes into the front in a standard way. I will of course be taking the fuel out of the system for the eberspacher as early as possible so will only be on the sender not the return that I need the size for. Below is the only pic I have at present. Would these be 8mm as Orgasmic Farmer suggests? Quote Link to comment Share on other sites More sharing options...
miketomcat Posted February 13, 2012 Share Posted February 13, 2012 May not help but my standard black plastic fuel line was 5/16 (200tdi) and this is land rover they tend to fit till they run out then swap to the next size. Mike Quote Link to comment Share on other sites More sharing options...
Ex Member Posted February 13, 2012 Share Posted February 13, 2012 The main stock fuel lines are 3/8" nylon tubing (not hose). Some of the ones around the engine are 5/16". As you obviously do not have any stock lines, why are you asking?? Back to the topic....it is "best" to not tee into a fuel line for a Webasto. It is "preferred" to put in a dedicated line to the tank. The reason is that the Webastos do not like any air bubbles in the line. If you do tee in, make sure that it is between the tank and the lift pump and that the length of the lines and location of the fuel pump meet the requirements shown in the Webasto installation manual.

PieEater3142 Posted February 14, 2012 Author Share Posted February 14, 2012 Thanks guys, I didn't fit the fuel lines and dont have any calipers to find out what's on there. Running the fuel line to the tank is not really an option, so I would be going into the braided hose just before the lift pump. Can I assume then that the line is 3/8? I found a pic of the line joining the lift pump from when I got her. Does it seam reasonable to assume this is 3/8? Quote Link to comment Share on other sites More sharing options...
Ex Member Posted February 14, 2012 Share Posted February 14, 2012 You can't assume anything, because it is not stock. You need to measure it. If that photo of the tank is current, it would be very easy to add another line. Quote Link to comment Share on other sites More sharing options...
PieEater3142 Posted February 14, 2012 Author Share Posted February 14, 2012 Unfortunately I have the tub sides roof etc on now - the tank is well and truly buried. I can access it using the drop plate but i really want to avoid that as I will also need to run the line down as well under everything including seatbox floorpans etc :S Quote Link to comment Share on other sites More sharing options...
Frax Posted October 27, 2012 Share Posted October 27, 2012 Did you get your heater fitted yet and can you tell me where you put it, I am just about to do the same job - ever thing here now and tested just need a tee for fuel line and a place to put the heater might go in the back up against bulkhead but open to suggestions. I have a 300tdi 90. Any help would be great. Frax Quote Link to comment Share on other sites More sharing options...
vulcan bomber Posted October 27, 2012 Share Posted October 27, 2012 Why did no one suggest taking it from the filter housing? Theres piped outlets there for just this sort of thing. Quote Link to comment Share on other sites More sharing options...
Frax Posted October 28, 2012 Share Posted October 28, 2012 Looked at that but its to high up and if air is going to get into the system that is where it will land up especial when the Defender is not running. Quote Link to comment Share on other sites More sharing options...

Air only gets in if you've got a leak and you know when you have a leak because they become a pig to start. Quote Link to comment Share on other sites More sharing options...
Ex Member Posted October 29, 2012 Share Posted October 29, 2012 These things hate air and it is so easy to get small air leaks. It is always best to run a dedicated line. Quote Link to comment Share on other sites More sharing options...
