Over the weekend I installed the Fore dual pump fuel hat as an upgrade to my dual pump setup from Arrington. The Fore had is just billet goodness and is a very nice piece. No rubber hoses or anything, all the fuel flows through channels in the aluminum making it very robust.
I opted for the Arrington upgrade to the wiring harness to get the load of two pumps off my stock wiring that's deigned for a single pump. A couple of times when working on the car I noticed the wiring at the fuel hat was warm to the touch. With the new Arrington harness (designed and produced by forum member Rwamser) it no longer gets warm at all. The power and ground wires to the pumps are upgraded to 10ga wire vs. the factory 16ga. The harness is also designed to handle 25+A of current with an inline fuse and 30amp relay. The instructions are well laid out and all the connectors are the nice Weatherpak type that are more heavy duty than even the stock connectors.
My fuel pressure went up about 8psi at the rail to boot, I believe due to the pumps getting more current than on the stock wiring.
Two Walbro 255LPH fuel pumps draw around 18A. The stock fuel system is designed to handle 20A so you're right at the limit on the stock wires.
There's video on my site of the install. The hardest part is the fuel level senders as you need to make some connections right at the fuel hat opening in the tank. That and the fact that Dodge used some wire colors twice on the connections means you have to pay attention to what pin goes where. All in all not too bad, but you do need to take your time and pay attention.
Make sure you have 1/4 tank or less of fuel before cracking open the hat.
Here's the pics....once the video processes on YouTube I'll add it here, but it's on my site currently.
