Help with fuel filter please!

Post by Frances » Wed Sep 07, 2005 4:46 pm


Having real problems with our BX TZD, which sat idle over several months, and we have just got going again. The engine fires, but won't keep running, except at high revs.

We're trying to check the filter on the hand primer - seems to work OK, but there is a black nozzle-thing on the bottom which looks as if it should be connected to a pipe - but there's nothing there. Should it be connected to something?

Here's the picture:Image

That is a water drain tap, push a bit of pipe on to it, lead it into a can and undo the black bit and any water in the filter should drain out.

If it is firing but not running unless at high revs, its probably air in the fuel system. I had a similar problem on mine, the primer on the fuel filter didnt' work, so I bought a cheap primer bulb one from a marine supply place, plumbed it into the intake side of the filter and used it to prime the engine until the bulb was hard - open the bleed screw on the pump side of the filter until you get a nice solid fuel stream. Start the car and see if that works better, if not its likely the fuel preheater on the back of the block - mine was leaking air there as well, so then ran a new line from primer bulb directly to fuel line under car and it solved all the problems.

Yeh, those dreaded fuel heaters, nothing but trouble, my advice. Bypass it. :)
