Well, if seems that this ordeal has turned into a little project!
I got a free Walbro fuel pump from a co-worker. He told me it's rated at 170lph @ 55psi. Plenty for what I need.
Yay!

This would be a simple swap, but my fuel canister has a venturi pump in the bottom to pull fuel out of the tank into the canister. The venturi setup works very well to empty the tank completely. Anyway, The problem with the Walbro pump is there is no fuel outlet for the venturi pump hose. The typical way people have fixed this problem is to either put a 'T' into the main fuel line, or do away with the venturi setup all together and cut out the bottom of the canister to allow fuel to get to the pump...
I don't like either way. The Walbro does have a pressure relief port on the top and there is an after market fuel pump (racetronix pump), who modify the walbro pump to allow usage of the factory venturi pump. I believe they turn the pressure relief port into the venturi pump outlet. Sooooo I'm simply going to do this myself.
Tonight I removed the retainer that holds the pressure relief spring and ball in place.

Here's the ball and the spring. I don't have a pic of the retainer because it shot out somewhere once it got loose. lol

I plan to epoxy the venturi line into this port tomorrow, like this..

Then all I need to do is change the terminals on the factory pump harness to the style the walbro pump needs, and it's time to install!!
Also, does anyone know what this thing does? I'm kinda thinking it's for electronic noise suppression, but I'm not sure.
