I was ok with that, but after months, and no response. I modified the stock stuff to work.
The hat is modded as follows. I cuteas off all the stock lines except the rollover vent thing. I used 90* bulkhead fitting for -10 feed and -8 return. I got the 3 into 1 shower head block that MightyMouse shows in his dual pump writeup. I went ahead and ported it for better flow. I got the very expensive submersible SAE Gates fuel line to connect the pumps to the distribution block. I ran all new 10 gauge wires to the pumps. And then coated the whole top with a special Loctite epoxy to seal everything up. I cut the trap door in the floor to access it, the -10 sits slightly too tall, but I taped the access panel down with a slight bend to clear it. Each pump has its own dedicated power wire to the battery with fuse holder and relay.
you have any pics?
