885 fuel return pipework

Post by garymiller » Wed Dec 13, 2017 8:00 am

Sometime ago I removed the fuel return pipework from my 885 and it pretty much fell to bits, I replaced it with fuel hose and t pieces but I now want to hard pipe it.
I bought a pre formed piece of pipe from John County but it doesn't have a tee off for my hot plug...which my tractor is addicted to after standing for more than a day.
My question is are the fittings available to splice in an an additional take off for the hot plug...either compresssion or solder/braze?
Is this the correct place for the hot plug fuel supply or is there an alternative?
Does the hot plug actually need a fuel supply or can they be un without?
Interested to hear all your thoughts

Yes, it needs a fuel supply. You do not mention the little header tank for the thermostart, see 31 on the link below. You cannot just have the thermostart 'T' in to the returns line without this tank. You should have no problems getting pipe fitting at an hydraulic repair/sales shop.

Thermostart kits are available from davidbrownparts.com
Are you using the cold start device on the injector pump?

Ah ha!
I never mentioned the header tank because I never knew it existed!
Mine is a simple tee into the return pipework, originally with a metal to fuel hose.
When I use the thermostat I hear a pop from it which I presumed was the diesel igniting on the hot coil?
And yes I still use the cold start on the injector pump.

Not all DB tractors were fitted with a small tank. The pipe from the return line to the Thermostart was coiled and this held an adequate amount of fuel.

Mine has quite a bit of slack built into it so I'm likely getting away with it.
Just out of curiosity what sort of volume is the header tank, it looks quite small?

The amount of fuel in the Thermostart reservoir, ref 31 the link supplied by db780, is more than adequate for the Thermostart to work long enough when the preheater is in operation . The reservoir will be automatically filled by the return fuel from the injectors and the injection pump whenever the engine is turning.
