Fuel pump for lifting fuel to surge tank

[cloughy]

You need to get a pump that goes in your tank to supply the surge tank IMO. The facet style pump is fine but if the pump loses fuel supply for some reason then you will have to prime the pump again for it to start sucking, whereas if it is in the tank it is submerged.
Example: If you have say 1/4 tank of juice and your on a big f@# off hill then the pump supplying the sugre tank may suck air for a bit (which is fine because have the surge tank full of fuel) then when it goes to try and suck the fuel again it will suck air and not work. If the pump is in the tank then even if it loses fuel for a minute or 2 then it will be covered in fuel and suck fine again
My thoughts only

I've NEVER had to prime a facet solid state pump

With the conversion of my P40 MQ to efi with a Falcon throttle body (See my thread on this board) I just used the existing MECHANICAL pump to feed a 2L surge tank and then an external Bosch pump to pressure the injectors which, with throttle body injection, requires only 15psi or so (the Bosch is overkill but I got one at a good price). I went the surge tank route to avoid messing round with my unbaffled main tank and to avoid hp fuel lines running the length of my truck. Have had no problems so far. See schematic below

Now a question - can anyone suggest a good surge tank donor at a wrecker? I don't really need a bling bling aluminium ricer surge tank, anything'll do me especially if it comes with a lift pump too

There is a guy here in NZ who makes top class stainless steel surge tanks to order for around $NZ100. Puts inlets/outlets just where you want them (important) with whatever thread you want. I have used one on my conversion.[/i]
