    Apologies if wrong place for this..

    Currently sorting out a RRC/Series hybrid for trialing/offroad use, it's got a hgv fuel tank mounted in the pickup bed and a facet electric fuel pump and regulator mounted under where the middle seat would go. After sorting some pipework issues out the V8 is running almost as it should.

    I plan to replace the rusty old tank with an ally/stainless one with more baffles inside to sort out lack of fuel pressure at certain times, and the lack of a separate tank vent and fuel gauge. The pump will be moved as its too close to the prop and exhaust for my liking. I am thinking to mount the pump either next to the tank in the pickup or in the engine bay, depending on whether I fit a swirl pot if the new tank baffles aren't up to it. Would be interested to know what others have done for this.

    Is there any reason why I can't replace the main run of rubber fuel pipework with copper and fix it with rubber lined P clips, then have rubber pipe coming off that for the final connection at both ends. This would be underneath so not inside the cab.
    Many thanks

    Kepp the pump close to the tank as they don't like sucking, and have the regulator as close to the engine as you can, so that for the majority of the run you've got the full capacity of the pump and it just drops the pressure at the end to give the needle valve an easier life
