Need to replace the tank to lift pump fuel line on my 1988 110 with a 200tdi engine and just learned that ESR246 is now obsolete just like the NTC7979 it replaced. No alternative seems to exist. No one I've asked seems to have any old stock either. :facepalm:
Has anyone dealt with this or do I have the honours of being the first one?
So far, if I can't find an alternative, the plan is to get a diesel fuel hose and reuse the old fittings, but I hope someone can recommend a better solution.
BTW, can anyone confirm Defender 200tdi lift pump specs, specifically, operating inlet pressure? I saw somewhere that it's around 11psi which seems low?
I used standard fuel line from napa for my 200tdi when I replaced the tank, doesn't need to be anything special as long as it's the right size. I don't recall the inlet pressure but think you're right, it is low. edit to add yes, I reused the fittings and added a few at the lift pump.
Check out Grainger web site. I bought fuel line for my return line on my 19j engine. Other than the color which was yellow it work out well. I just split the old fuel line and used the barb fittings. After a year no leaks. check them out.
The stock line is 3/8" nylon tubing. Cheap and easy to find. I like to use air brake tubing. It is nylon with polyester reinforcement. Better kink resistance, UV stable and the nylon is chemically stable to all fuels.
Alex:
I think you are reading too much into your "must replace with original factory line" scenario.
If it were me, I would be celebrating that the shitty plastic fuel line is NLS.
That gives you the opportunity to install a buna or a viton line if your fuel is vegetable based.
So the optimal fuel routing is tank -> sedimenter -> 12V fuel pump -> engine lift pump -> Fuel Fuel Pump -> IP -> return line joins with the spill over line -> tank.
In this way the fuel system is reliable and self bleeding with fuel line that is much more reliable than the cheap plastic OEM stuff.
If you want reliability, this is the way to go.
Thanks, everyone, for your help and great suggestions.
