HI Possible to relocate fuel pump?

Hey guys I was wondering if it was possible/if anyone has relocated their fuel pumps on their first gen. The reason I want to relocate mines is because it is the lowest point on my car and I wanted to lower my car a lot and I dont want to have to worry about hitting the fuel pump.

It shouldn't be the lowest point.

All of this fits up higher than the bottom of the bodyrail.

I lowered mine 4 inches on REspeed coils and never had a problem. If your dead set on relocating... I've seen people put the pump in the engine bay near the hood latch. Wiring should be easy tonre locate. Then just run an extension barb to connect where the pump used to be.
Heat could be an issue for the pump though in the long run.

I moved mine to back behind the drivers rear wheel well in the small space next to the gas tank

The OEM location is much better than underhood. Aside from the potential issue with heat, fuel pumps are good at pushing / and suck at sucking. Any heat makes the condition worse. The lower and further back, the better.

Thanks for the advice guys, its just when I bought my fb the guy had a carter fuel pump on and I noticed it was the lowest point on my car for some reason. I probably only have to ziptie it higher or something but was just curious to see what everyone had to say.

And that's the reason for the fuel bomb / moonshine still looking mess of plumbing under my car. The fuel pump in the STOCK location would cavitate trying to pull fuel up and back down, causing all sorts of weird issues, and if it sucked air even once then it would take about 100 miles of cruising for the air to work its way back out... and heat makes the air pocket bigger because air expands when hot...

(The square pump and the return from the engine feed the mini-tank, the mini-tank feeds the pressure pump. Works exactly as intended)

Not sure I'd try to drive that car across the border. Your "mini-tank" looks like a pipe bomb
