RM1013 has been happily chugging around Prague this season but recently it ceased chugging. I've been away and in my absence our Czech engineer chum attended the scene and diagnosed the fuel pump diaphragm knackered and got it home by jerry rigging an electric fuel pump.

Are replacement diaphragms available and/or can a replacement be manufactured if we know the right grade of material to use. Having not seen it yet I'm guessing, obviously.

I've found a company on t'interweb claiming to make new pumps in Turkey.

Does anyone have experience of their products?

Many thanks

Hugo.

You could send it to one of the Fuel pump specialists in the UK for an overhaul or buy a proper replacement one. Is it on line or DPA and which engine does your bus have?

Also check RM Assoc suppliers list for contacts.

My bus number (if any): RTL 960, RM 1585, RMC 1485 and several RTs

J&S Diesels of Rochford have overhauled lift pumps for me recently. I may have one in stock as an exchange unit if that's any help.

I've worked on several RMs in Europe with electric lift pumps, including one fitted with 2 pumps!! The problem is that electric pumps lift at about 3 bar, the RM needs about 0.3 bar, so the excess pressure can feed back through the injector spill-off pipes and cause all sorts of other problems if your injectors are a bit knackered.

My bus number (if any): RML2532,GS67,MLL721,MLL738 and an RT.

Thanks chaps for the responses.

1013 is a very unmolested example with its original AEC engine. (well if the register is right then we think that the chassis and hence engine I guess, previously belonged to RM1032).

Thanks Roy for the tip about the pressure, having made it home it'll be off the road till we get this fixed now. We might very well be in touch about your potential 'stock' of reconditioned pumps.

Cheers,

H.
