Just thinking out loud a little....
What about using a small block Chevy oil pump as a fuel pump?
There are a couple of obvious problems with this...
1) they seep oil around the shaft.
2) it will make a lot of pressure
3) how do we power it?
Here are my thoughts. Please feel free to jump in. I'm looking for discussion.
1) For myself, I would use the pump with a large bed mounted tank. The pump could be used much like it is in a Chevy engine. i would shaft drive it with a DC motor from outside the tank. Perhaps the motor is mounted on top of the tank with a shaft down to the oil pump down low in the tank. This would allow the weeping to remain inside the tank.
2) I'm not sure about this one. Obviously you could use an external bypass regulator such as one: http://www.summitracing.com/parts/aei-13301/overview/ . but that makes the total cost not acceptable I suppose. What if a couple of coils were cut off the internal pump bypass spring? I don't know myself.
3) To me this project would only be feasible if we could come up with a cheap DC motor to use such as a windshield wiper motor. I have know idea how much power would be needed or how many rpms would be needed. Anybody got thoughts on this?
I know we can buy a decent WMO pump in the $150 to $200 range. My reason for thinking about this project is simply because I like to build crap if/when it's feasible and cost effective. Also this could be a modular project in that you could be a sbc pump this week and a motor next week as an example. I also like the modular idea in that if a part breaks then you replace the part and not the entire unit.
Anyway...this is just for a discussion for now...So what do you folks think?
PS...I wanted to add an edit to clarify just A little. I'm looking at this project as a lift/fuel pump and not as a transfer pump. Sorry for any confusion
