Hi there,

Does anyone have a service manual or spares for the now long obsolete BM
Controls Type 346 oil lifter? In particular details for the disassembly
and servicing of the oil pump impeller?

It has been unfortunately gummed up by bat dung over the summer and
routine servicing of the filter and cleaning out was not enough

Thanks for any pointers to info - or to a BTEC registered oil line
technician in the north east who could repair the oil line system.

A starting point for you perhaps?

It was actually solved. The small horizontal pipe at the bottom of the
tank had a tiny crack in it and cleaning out the bat dung which was the
consistency of putty had allowed it to weep - defeating the pump.

Once the pipe was properly sealed again the pump could lift fuel from
the main storage vessel instead of merely moving the priming fuel around
uselessly from one side of the pump to the other.

They are insanely expensive. Much more common in Belgium and Denmark
where fuel oil tanks are often in cellars.
