Does anyone have a diagram of the fuel line attachments in the tank between the pumps, filter. and Pressure regulator for a 2005 Cayenne 3.2?

I do not.

I opened a post in our forums. A Pelican community member may be able to answer your question.

This is how I attached mine. I have not encountered any fuel system issues to this point, but am not even to 1,000 miles since the fix...

Once both pumps, the FPR, and fuel filter have been removed, there should be four connectors left inside the tank (excluding any electrical clips). Two are the black plastic clips that attach in only one location on each pump. Those click right on after you have screwed the pumps into their retaining rings. The other two are male fittings attached to orange hoses. Each one starts on one side of the gas tank and crosses over to the opposite side.

1. The filter (driver's side) has a hose with a 90-degree female fitting. It crosses to the passenger side and attaches to the FPR male fitting that points downward toward the bottom of the tank.
2. There are two hoses in a "Y" coming out of the passenger pump. One is male and the other is female. The female attaches to the FPR on the remaining male fitting. The male end attaches to the long hose that comes from the center of the driver's side pump once it has crossed to the passenger side.
3. The long hose coming out of the passenger pump crosses to the driver's side and attaches to the filter. Only one of the two male fittings on the filter will accept this hose. The other male fitting on the filter accepts the medium-length hose coming out of the driver's side pump.
4. The short hoses coming out of the center of each pump accept the males hose fittings that are attached to the orange tubing.

My attempt at a diagram (6&7 get the orange hose male fittings not shown):

I did my 06 Cayenne S last year myself, I believe I may have a picture. Be sure when reassembling to make sure the hoses don't interfere with your fuel level sender. One of mine, I believe pasenger side is obstructed and my tank only reflects 3/4 full now. I'll fix it later but it's annoying to see it like that.
