Hi all,

I've just got a share in a narrowboat fitted with a Lister SR2 engine. There are 2 fuel filters as per the picture attached, but I'm not convinced the filter cartridges and/or "O" rings have been replaced correctly - there has been a deal of leakage, both of air in and fuel out. Does anyone have a definitive drawing of the internals, please? I think I can see where most of the "O" rings are supposed to fit, but I'd like to be certain, and I'd also like to be sure I have the paper cartridge in the right way round, as they're different in the two filters. If it's not clear from the picture, the filters have the securing bolt fitted from underneath the bowl.

Thanks in advance,
Trevor
