RE:fuel Preporater
March 19, 2004
I just installed the fuel preporater with some phone help from Charles. What a great guy to talk to. He spent a lot of time explaining how it all works, etc.
It went well. I did not change the fuel tank pick up line but will at a later time with 3/8 or ½ inch line. I also connected the stock fuel filter canister in line with the preporator so I will have a fuel heater. That way I will not wax up my VP44 pump when it is cold. How I know to do this, I spoke to an engineer from Bosch Germany who helped engineered the making of the VP44 pump. Also got lots of other info that I wont get into at this point. Also the preporator filters at 10 microns and our stock one filters at 2 microns and the stock canister does not have much flow restriction. How I know this is I did a flow test on it.
And a BIG thank you to Bill and Steve for the stock filter canisters that they donated to me. And cant leave out 4X4 Bob for all the many lift pumps.
You could also connect in line your stock lift pump and it will flow fine right through it.
Tested that also. So all you FASS guy’s good luck in the winter with no fuel heater! Unless you connected one up with using your heater hose?
I also mounted a max flow kit from the stock filter canister to the VP44 it uses ½ braided SS line and fittings and 3/8 Goodyear gorilla hose lines the rest of the way down to the pump then to the tank. The fuel preporater return line to the tank over flow I used ½ inch gorilla hose and ¾ inch Y with ¾ inch gorilla hose. I mounted ½ inch SS shut off valves with locking handles pre and post of the pump. Also makes for a Great anti theft device!!. I pre filled the filter and water separator and then bleed the system by bumping the starter a couple of times and letting the fuel run into a 6 gal gas can then reconnected to the VP44 and bump the starter again after that started it. It started right up. My psi at idle 15 psi and giving it the go paddle it is 14 psi. It will improve when I replace the pick up tube in the tank to 3/8 or ½ inch lines. Which will be done soon. I noticed when running the motor it doesn’t smell as bad which is clean burning. Smokes less when given the go pedal.
I will update when I put some miles on it. Im off to a good start.
Off to the Dyno oh I for got stall have to install kev's pump then Off to the Dyno
