[T3] Injector hose

[William Jahn]

The Gates Barricade hose is 5/16" ID yet it is stiff and is difficult to
get over the fittings with a bulge. It does not stretch well so you need to
lube it which seems to be true of most fuel hose . I had some German hose I
got from the bus depot that was good and lasted 10 years , still needed
lube to get it on yet the OD was smaller and easier to get the clamps on. I
still need to replace the under the tank lines , I did replace a few
because I replaced the pump with a 2 port, this was just the return lines
and tank to filter to pump. I did the engine and engine to the rear of the
pan.

 I wonder what people use to drain the tank. I don't have gas cans and also
wonder if you siphon from the filler into a can this new fuel might affect
any hose . I'm not sure if using the fuel pump would be a good idea. A hose
on the pressure side into a gas can might just start a gravity feed in the
gas can is lower than the tank.
