I've gotta get some parts, drop the tank to verify I've got a walbro at all which I'm sure I do
Parts required to drop tank:
-phillips head screwdriver
-12mm socket or wrench
-17mm deep socket, or wrench
-Pliers to get the lines off (maybe a 12 and 14mm wrench for the feed too, I can't remember)
I can drop the tank in about 20 minutes if it's near empty, a little longer if I have to do it full.
As for your fuel pressure dropping off, you're running 540cc injectors you said right? I'm going to assume a base pressure of 43psi? Have you ever bothered to calculate the flow at 13psi of pressure? I could do the calculations for you if you like, but I think you're pretty close to the flow limit for a single walbro. Sure they sound impressive at "255lph", but they drop off flow HUGE as pressure starts going up.
Oh, what turbo(s) are you running?
And people wonder why I hate walbros so much
