I have the 12 gauge connector. There is no connector on the pump.

2nd option isn't fuel safe.

 

Pump is hardwired, I was just thinking using the Metri-Pack 280 (10-12gauge) female pigtail to plug into the stock Walbro male pigtail (uncut), then the free end of the female pigtail to repin the stock tank side connecter to the stock feed through. 10-12 gauge up top;

should be fuel safe because it's the connector the pump came with.

 

The bulkhead connector you posted.

 

Got it, I misread fuel pump wiring through firewall as through fuel cell (had other windows open). Removed this from prior post to curb misinformation. Thanks for clarifying.

 

I did the same.

 

Sorry dude, didn't mean to mud up your thread.

 

No worries. Good links to those parts.

 

metal feed through?

This is cheaper, what I plan on doing...



Go back to the conduit section at home depot, grab a short 1/2npt to 1/2npt coupler and cut it in half. Weld the new bungs onto the pump plate, then screw these in. That's an 1/8NPT plug drilled out to 10-32 inside a 1/4npt nylon reducer bushing. Solder FP leads into the brass, thread them down into the reducing bushing. Only real big bummer is it's gotta be done with the leads fished through the FP mounting plate, or you'd have to split the voltage and ground wires somewhere inside the tank...

With the 10-32 hole soldered completely shut there's no way fuel would wick out...

 

Cheaper if you already have a welder :(

 

You could try and find a 1/4NPT locknut, then coat the whole mess in epoxy. I couldn't find them in home depot or menards, probably gonna have to be an online thing.

Stupid question, but is there an easy way to get from the battery to the gas tank? Pre drilled holes or anything? For wiring.

 

The filler neck hole?

 

Haven't looked over there. Would have to go across the trunk, which isn't my favorite.

 

Here is what I ended up with for wiring so far. Had to go to dinner so didn't get the pumps swapped.

Grommet into the tank area.



12awg harness wrapped in sheathing. Spade terminals for the relay, ring terminals for the battery.



Hose clamps holding on the wiring. Might switch to zip ties if I need those hose clamps back at some point. I need some of the zip ties that you can stick in the holes.



Ground and F/P wire taken from the stock connector.



And here it is hooked up for testing with the stock pump. There is about a 1/16 of an inch of dirt covering the entire tank.

It works

 

Holy **** this thing is loud. Sounds like someone turned the faucet on under the hood

Not overkill at all
