Excellent work guys!! Love the build Coach. Just throwing this out there, but I would reconsider a double pump system on a stock feed line if that is what I am seeing in your pic posted of the fuel filter. That could possibly lead into pump problems down the road trying to feed 2 pumps on that line. Not worth the risk on a no expense spare venture like this. The inside dia on the lines at the end where the fittings are, is smaller then the inside dia of the line itself. IMO, it's going to over work your pumps. Minimum "I" would use would be a #8 line as a feed.
Keep plugging away boys, I'm extremely eager to hear it running.
