Fast_Freddie's crack at double pumper fab

I know it is not a fatty bead, however it is a fabrication thread...Yes it looks uber similar to the two oem hanger kits available, however once you actually get in to it that is about the only outlet configuration that works well. I got all materials including hangar and an extra pump for around $280.

Materials needed...

Oem hangar off ebay- $75 shipped

x2 5/16" single tank fittings from Dennis Kirk (Dennis Kirk Part #: 182086)- $18 shipped



x1 5/16" stainless "Y" fitting ($28 shipped)
x1 walbro 342 with fuel sock and harness ($110 shipped)
1 ft of 5/16" gates submersible fuel hose ($20 shipped)
I got all this from lightning force performance since they had a spare pump laying around for- $135 shipped



x1 Liquid tight cord grip P/N 7807K31 from Mcmastercarr- $9 shipped



x3 feet of 30R9 fuel injection hose- $21
x1 Wix fuel filter P/N 33310 (for Audi RS6, 5/16" on both ends and 40 micron)- $10
x13 #15 fuel injection hose clamps (for 5/16" ID hose)-$9
x1 pack of nylon washers from Lowes-$1
x1 pack of 7/16" ID fender washers from Lowes-$1
x2 7/16" x 14 thread pitch jam nuts from Lowes-$1

As for the 90* tank fittings I ground down the grommet nipple and threaded them with a 7/16" x 14 thread pitch dye to create a bulkhead fitting...

I also ordered 2 weatherpack connectors (2 pin and 4 pin) for a nice wiring install... here is the wiring diagram I drew out...



Here are some of the pics... waiting to get the car back to install the pumps, but test fitted with 2 oems pumpsI had laying around...

I think you will run into problems with those bulkhead fittings..They will probably be a bit to low, so you may need to trim them down to get the pumps closer to the cover..I had a hard time finding correct bulkheads and when I found the best option I still had to modify it to get enough clearence for the pumps. I also did a hobbs swith with metri-pak waterproof connectors. My kit does not leak air or fuel at the fuel hat connections like I have seen so many others do. This is important if you do not want fuel odor. I also used russell pro classic hose all black with black AN fittings, servicible filter, and an EFI hose end that snaps right onto the fuel line just like stock.. I didnt really take pics but this is what I took before the install..I also ran an led next to the boost gauge so I know it kicks on..

As in the pumps configration being to long to seat into the tank hole? Measured it is about 1/2" longer than the stock hanger configuration... however my socks will be in a different orientaion... we will see when I get the car back, as I have nothing to test fit it on... this is all eyeball so far...

I will be wiring them up to run both pumps together, no hobbs switch. If I can't control the fuel pressure at idle, I will put the stock siphon back in and then run a hobbs switch...

For the bulkhead to the pumps I used some bosch fittings from jay racing _6AN female these were the only ones I found that gave enough clearence. The rest is russell fittings..

Aight, had a chance to install the double pumper today. I am running both pumps together with a drilled siphon and the OEM FPR. Before the install I was at 54 base fuel pressure with a relay to the single pump. After everything was hooked up I am now at 60 psi base, not over running the stock regulator, but of course probably not making it a true 1:1 ratio. The car still idles at 14.7 so I can drive it until I get an adjustable FPR to drop the pressure back down a bit. I will update the thread again when I get all that installed.
