I thought my fuel system was air-locked. In fact, it appears that
there was a blockage in the fuel pump - the plunger wouldn't move. Of
course when I poked into the hole (as you do!!) the plunger popped
out, in pieces (as it would!) I reammembled it (using my initiative -
and this is probably the weak link in the process!) and replaced it
back into the pump. Fuel now passes through - but to excess ithink,
as the boiler only fires (very loudly) for a short time before blowing
out. Any ideas or has anyone a diagram of this pump? It'ss a fairly
old system (installed about 30 years ago; boiler casing says Thorn,
motor says Compton..?, fuel pump has Danfoss? on it and there is a
label with an arrow and S & R at either end.

Go and look on the Danfoss Web site for a suitable replacement pump, then buy
one from someone like HRPC.

The pumps dont last for ever. (well not in my house!)

Also buy a pressure gauge with T piece and maybe a high pressure flexible hose.

Install new pump and set to work at correct pressure.
