I thought you went with the Walbro's instead of the Skyline unit based on price!? Why not just get a unit that flows more by itself rather then have some custom twin unit fabbed up?! Regardless, I don't think I can roll that high on the $$$ personally. $400 max for the pumps and the rest is suppose to be R&D? We get screwed on everything. Wes got a an engine put in his Jeep for less then that.
BTW - this post wasn't to offend, just sayin my piece.
