    Dam! what do they say about great brains think alike!
    that is exactly what im doing to the disco on saterday!!!
    LRHybrid100 are you using the primer pump that goes inside the
    VL tank? i was thinking that I ll need it to get the fuel out of the tank and into the High pressure pump?
    what pressure range does the VL reg go to?

    cheers discowhite

    G'day Discowhite,

    I didn't use the primer pump - just the VL bracket and in the end a brand new Bosch pump.

    I removed the metal pipework that sits on top of the tank and used 5/16 flexi efi hose to the reversed filter (filter now flows towards the back).

    Then a u bend in the flexi pipe into the Bosch fuel pump then finally a bit of an "S" to connect to the standard fuel lines.

    The VL pump runs at 3 bar (approx 42 psi) and the RR needs 34-37psi.

    The Bosch part number is 0580 464 070 - I paid $175, but have been quoted nearly $300 from Repco!!!


    I'm PM you my mobile number if you need to discuss anything.

    Hope this helps LRH.

    Good job and well worth the effort.

    I did the conversion some time back, I notice you don't appear to have a primary filter on the suction side of the pump and I can't see the large filter on the discharge side< I assume you have the latter but it's a good idea to put a primary filter in to stop junk getting into the fuel pump.

    A couple of pictures:

    G'day Richard,

    yep saw your pix on Zorbas site ages ago!!!

    I did mine slightly different, I put the fuel line from the tank straight to the filter (reversed the filter, so it now runs towards the back of the car) then into the pump and then finally into the fuel lines.

    thought it would save another filter - will replace the standard filter more often now also.

    LRH.

    Nice Work. Great Minds think alike 8) . I had fuel pump problems driving Perth to Melb and was left stranded in Port Augusta with no where to get a Rangie EFI pump. I got the VL external pump from the local repco store ($200) and fitted it in line without removing the original pump. It sucked fuel through the original pump and got me out of trouble.
    When I got home I pulled the original pump out and found that it still worked. The LPG installer (under vehicle conversion) had crimped and joined 3 pieces of wire to get from the original loom to where the smaller petrol tank was now located :x . Poor electrical connections had meant a significant voltage drop. I decided to rewire the original pump as well as leave the VL external pump in as a back up.
