I'm looking for a consensus, or at least some discussion, on the best lift pump set-up on a TDI engine swap. I'm putting a BHW into a small 2WD pickup truck. The aftermarket fuel tank has a top opening of just 2-1/4" diameter, with a 6-bolt flange for six bolts on a 2-3/4" bolt pattern. Fuel suction is only from the top. I'm planning to utilize the existing engine fuel filter.
My understanding is that the fuel feed system should run 5-9 psi with around 180 LPH (48 GPH). My intent was t utilize the VW's oil cooler piping for both the feed and return lines. I'd love to use an in-tank pump to cut back on noise, but with the small access opening, options may be somewhat limited.
I did fiind a couple of Walbro pumps that can be incorporated into this tank. Model 5CA401 puts out 30 GPH at 7 psi, with a max pressure rating of 30 psi and free-flow rating of 32 GPH. The GSS0242 puts out 53 GPH at 7 psi with a max pressure of 100 psi and free-flow of 56 GPH.
I noted that several folks are using a Facet solid state pump, like the 40107 which has a max-to-min pressure of 10 to 7 psi and flow of 34 GPH. With this set up do you utilize a return line and use a regulator on the line back to the tank? I do hear people complaining about the clicking noise with these and wonder what kind of life you're getting with them.
And then there are the rotary pump options, like the Carter P4594 rated at 5-9 psi with a max flow rate of 72 GPH. With these, I expect you have to put a bypass around the pump in case it quits on you while out on the road.
So all you with those TDI Conversions: How did you set up you fuel supply? Are you happy with what you've got? What might you do different now that you've driven it for a while?
