electric fuel pump mod?
I have a fuel leak SOMEWHERE in my valley.. pretty sure it's the lift pump but I'm not REAL sure.. but I figure if I'm going to go tearing the fuel bowl and stuff apart I might as well spend a few bucks and upgrade the darn thing.. any of hyou guys do it? how? any pictures? what did it cost you? I'm loosing a quart or so of fuel a day I'm guessing now so I need to get on the ball about this. just got my twin 4" stacks done today and boy are they sweet 
thanks
thanks

You have some options.
You can get an elect. Walbro pump for around $100, or a stock SD pump for about $175, Aeromotive regulator for about $165, filter heads and filters for about $80, misc fuel hose and fittings.
Most guys (I think) tap into the fuel line in front of the selector valve on the frame rail with the elect pump. Install one filter head with a 30 mocron filter/water seperator, then to the pump, then to the second filter head with a 3 micron filter. Pumps like to push, not suck, so it needs a 'big' 30 micron (or 50?) to suck through, but can push through the smaller 3 micron filter.
Then on top of the motor, yank the pump and filter bowl. Adapt supply lines from the hardline on the motor to the 1/8" NPT fittings at the back of each head.
Fuel comes out the 1/8" NPT fittings at the front of each head, run lines to your regulator (1 in each side, 1 out at the bottom) then to the oem return hardline.
Wire your new electric pump with a relay, and some will mount a pressure switch on a motor oil port so the pump won't run if the motor shuts down in an accident.
That's how I'd do it, sorry no pics.
Good luck.
