Does anyone know how to rebuild a facet red top fuel pump. Mine was full of fuel and was running on a previous x1 9 but now you can hear it working but it doesn't pump fuel.

Cheers phil

Stupid question first - you have got it plumbed in the right way around?

Yes I have. if I put my hand over the inlet and outlet but there is no pulse... If you know what I mean.

So have you taken the end off and made sure the internals are obviously ok and filter not clogged up?
Is the pump fitted vertically?

All of the available service parts are listed here (on the last page): http://www.fuelsystem.co.uk/web-facet.pdf
The only useful parts to you are the filters, cap and unions. If the pump itself has failed I don't think there will be much you can do
