				My dual stock fuelpump setup!
			 
			
			Here's some pics of my dual pump setup using twin stock FD pumps. I used 10G wire and bypassed the stock connector by drilling holes and using grommets, then used 2 heavy copper ground straps to link the elect posts on the 2 pumps.I already have a direct wire from the battery using a relay triggered from the stock FP wiring. For the fuel part of it I cut the stock metal tube and slid high pressure 5/16" hose several inches over the tube and clamped it good with multiple hose clamps. I used a heavy duty Y splitter made from some sort of composite plastic that's fuel safe. Then ran the lines to the two pumps. Used large hose clamps to clamp the pumps together to the bracket. The pics were taken before I centered the pumps on the bracket so they would fit inside the tank, as well as before I coated and wrapped the hoses with fuel safe sealant. I also used sealant at the grommets. Overall cost was about $45 for the pump, extra sock, and sealant, already had the wires. Oh yeah the grommets are also sealed on both sides with a fuel safe sealant.

			Great thinking, not too expensive but get's the job done.

			Thought I would add a diagram of the fuel pump rewire. I did this first before adding the second pump, It makes a huge difference in the voltage at the fuel pump. Once I added the second pump I also bypassed the white fuel pump connector on the lid as you can see in the above pics. Now it goes straight from the relay to the pumps.
