RCR (River Canal Rescue) have their offices at Unit 10, tilcon Ave, Stafford and a neighboring business at Units 7/8 selling fireworks has had a major blaze http://www.staffordshirenewsletter.co.uk/Fireworks-explode-Stafford-business-blaze/story-23794587-detail/story.html http://www.bbc.co.uk/news/uk-england-stoke-staffordshire-29842252 as these buildings are in the same small block, I would expect RCR's offices to have been severely affected. Not good for them

Springy, I know what you mean about the plumbing on the filter head looking correct and I didn't think anything was amiss until I looked through a DPA pump manual. It was then that I realised, as Tony has said, that the inlet on the pump is the connection furthest away from the engine. Tony, thanks for your input. As mentioned in my original post, I am indebted to you for all the information I have gleaned from your website and as a result have only ever run my boat with the extra primary filtration you recommend. That's probably why I haven't written off the injection pump yet. The fitting on the filter head has confused me as well. It will be interesting to see what it is when I get up to the boat to do the work. There's no rush as it's currently winterised. Here is the Delphi non-return valve that I've got for the job (on the basis that if the device already on the boat is a non-return valve, it clearly isn't up to the task!) and they're different: Gentlemen, thank you.

Firstly may I say hello and thank you all for the useful nuggets of info I've picked up on this forum. Can I ask you fellow BMC owners out there If I'm on the right track regarding the fuel plumbing on my (plastic) boat: It seems to me that the DPA injection pump is receiving unfiltered fuel that has just passed straight through the filter head without actually going through the filter itself, the return from the pump then being fed back through the CAV filter the wrong way. I have owned this boat for the last three years and only spotted this error as I was preparing the boat for this winter. Apart from occasional tantrums I've put down to air building up in the fuel system, the engine has been a good starter and has run fine with the demands we've placed on it so far. That's probably down to information freely provided by Tony Brooks on his website - I chose to follow his recommendation of installing a sedimentor and primary filter (agglomerator) before moving the boat from where we bought it. When we got the boat the injection pump did look suspiciously new and having had no other filtration on the fuel supply before my additions, I can now see why. I'm also puzzled by the fitting on the filter head that is currently on the return port (but is connected to the pump inlet). It can't be a non-return valve because if it was, surely the engine wouldn't be able to run? Having read previous topics on this forum and various manuals downloaded from the web, I think I have a better understanding of how things should be on my boat. I am now in possession of the appropriate CAV non return valve, a spill rail that connects to the banjo bolt on the filter head and the appropriate banjo bolt (with the 0.5mm orifice). The new spill rail also has a fitting on the end to connect up to the tank return pipe (hopefully sending any air that's found its way into the system back to the tank). Now all I need is time on the boat to re-plumb it all. Anything I've missed? PS: I can't make my mind up between getting a Pela type pump for engine oil changing via the dipstick hole or whether to fit a pump to the sump plug hole. Any idea what size thread the sump plug is?
