Full Version: Fuel pump relocation 2 questions...

I am going to relive and change to a 2 port.
Found lost of good info here.

1. I can’t seem to find a late blister. Why couldn’t I just use a flat plate?

2. Am I correct in thinking other than cutting a door hatch and using the blister )or my home made door) that the fuel hose on this set up would be shorter and more protected than hanging the pump near the steering rack? The hose going out of the tank area then need to go back through just seems less desirable.

Got mine from Bruce Stone @bdstone914 a few years back. You might want to contact him. Good luck with your search.

As for the flat panel idea, it would probably depend what kind of mounting you will use and if your car has a front sway bar.

This is a picture from 914world and it also nicely shows the square filter and it's bracket. I think this filter with the tabs is difficult to find. I was considering removing the filter bracket in the back of the car and welding it in the stock 75 location.

Maybe someone would want to make and sell this (relatively) simple piece of sheetmetal?

With that style of pump and filter, you can mount them underneath the tank next to the steering rack. Use rubber standoffs to cut down on any vibration and noise in the cabin. No fuel smell in the front trunk and any leak would drip down onto the ground.

Copper line is not good in a fuel system. Copper will work harden with vibration, and eventually crack and leak.

Plus, some gasoline mixes will erode the inside of the copper tube and put crap into the fuel.

Thanks Clay, its not copper just has that look. This car will be used for mostly track events, so leaks or smell up front not a problem.

So the adventure continues. I purchased the relocation kit from AA and a 2 port pump.
Haven't decided on under the tank or at the steering rack location yet.
I have the lines done where the old pump was. so the "Y" is gone & wire run.

Issue is that the inlet on the supplied filter is 7mm (needs be 9mm) and the outlet from the pump is again 7mm (needs to be 9)
To do this right I would need two 7 to 9 adapters. Not loving that, as I want as few connections as possible.

Is that what you folks are doing?
Who has the adapters I need?

My advice is to mount it below and above the air diverter on the passenger fire wall. Much easier installation and easier to access. There are several threads on this going several if not more years ago.

I know Porsche changed the location to the front under the steering raxk on the late cars but I wouldn.t.locate the pump there unless you are going to replace the fuel lines in the tunnel. There are a lot more reasons in my mind to not to move it to the front but if you are planning on moving it there....plan on replacing the lines as well for one really good reason. blowup.gif blowup.gif

Edit:

See someone commented on that already....oh yea....don.t use copper...fuel corosion is only one reason not to use it.

Good luck.

Copper has no use in our cars but I think the pic is showing plated large diameter brake line which is plated that colour…..just saying or maybe copper confused24.gif .

I’m trying to learn (and decide) . . . what are the reasons not to relocate the fuel pump to the front? I’ve heard it said that a fuel pump should “pump not suck” and there’s the (recent) fire issue . . . yet I’d rather not cut any holes. . .

Brian,
I got my relocation kit from Chris Foley at Tangerine Racing. I am sure you can order just the bits that you need
