    Make it a hand pump with a non-return valve. Kills potentially 2 birds wth one stone

    Easier pump priming, and no drainback

    Something like this...http://www.ebay.co.uk/itm/HAND-PRIME...item1c2240480c

    However, i'm not sure about the hose size. Hopefully someone else here may be able to help with that

    You wouldn't need to prime it every time, only if it's "ever" run out of fuel Lot easier than waiting for the high pressure pump to draw the fuel through if it's run dry

    Added bonus of it having a non-return valve in it too

    Ah right,sori Mr Derv i must have mis-understood you,it might be an idea to fit one of those then,i just thought by the look of your`s that it would have to be primed on a daily basis on the 1st start of the day.
