The door handles are correct for that time period. Not sure if you have done so, but the VIN tag under the hood, on the driver's side firewall will also give you some info on the original paint color, motor, trans, interior, etc. Agree on the Renegade comment above. Original GPA status is more important, as you now know. Good stuff

Thanks fellas!
I'll check the vin tag under the hood to confirm more info.
Hoping to get it running this week!

I got a picture from him a couple of months ago with a huge elk in his front yard! He lives in town too.

You will enjoy living there.

Thank God for Grandpa's - love your Jeep, especially the white...

Today I got started replacing the old, dried fuel hoses.
Started up front and got the new hose from the carb to the new fuel filter, down to the mechanical fuel pump.
The return line off the 2nd outlet of the fuel filter turned out to be a smaller 1/4" hose, so I've got to go back to Napa to get that. But I figured I'd keep moving and replace the rest of the 5/16" fuel line.
So I started heading toward the back of the Jeep and here's where I got confused...

After the mechanical fuel pump, the line runs along the frame rail to what appears to be an electric fuel pump.
From the electric fuel pump...it runs to the tank.
The tank has 4 hoses to it.
1 line heading up to the electric fuel pump then to the mechanical pump, to the carb.
1 return line from the fuel filter.
And 2 other lines that run straight up to what appears to be...I'm not sure?

Anyone seen anything like this before?
Is there a reason for running both mechanical and electric pumps?

I'm a "Less Is More" "Keep it simple" kinda guy.
Is there any reason I can't ditch this electric stuff and just run a line from the tank, to a fuel filter, to the mechanical fuel pump, to the carb and call it a day?

Any help is appreciated fellas!

Yes, that's what's called a liquid check valve. It allow the tank to vent but not allow any liquid gas to tenter the line to the carbon container.

Very hard to find replacements. I cut the rubber hose to prevent the chance of breaking off one of the ports on the LCV

Interesting!
Thanks for that...I ordered an original factory shop manual last night so I do have that on the way.

So...can I just replace the fuel hoses, ditch the electric fuel pump, and leave the Liquid Check Valve lines in place for tank venting?

Edit: Just noticed the Carbon Canister has been plugged/disconnected.

Well you could hook up the canister again if you find random gas orders disconcerting .

Not opposed to it. But I'd kind've like to keep things fairly simple and clutter free.
I like the idea of a single fuel pump with one hose running from the tank to the carb. And the return/vent line too if the gas cap doesn't vent. Being low in the rear, I guess it makes sense you wouldn't want it to leak.

Just being me, I'd hook the charcoal canister back up with all the lines as original so it works as intended. It does look like some repair has occurred - silicone/caulking? Just make sure you don't have leaks.

Nice progress, keep the pocket knife and compass with the Jeep.

FYI that pump should have a filter in it. Twist the bottom and it comes apart.

The electric pump helps prevent vapor lock, you may want to keep it.

Thanks for the tips fellas!

Got more done today...
Got the fuel lines replaced.
Tossed an additional inline fuel filter between the tank and the electric fuel pump.
I also chased the wire from the electric fuel pump back to this switch on the emission control sticker. I turned the key halfway, pulled the switch and confirmed that it turns the electric fuel pump on...and it works! Kinda loud, but might be good for priming or vapor lock as mentioned...so I'm keeping it for now.

Got the tank out and empty of the old gas. The tank is pretty dented up on the underside but doesn't look too bad inside. Might just keep running this one since I don't know what the situation is on repop tanks for the 76 and how they fit. At least I know this one will bolt right back up.

Back at it tomorrow!
Got a 2 gal gas can full so might just be able to see if she'll fire up!

Update:

Still waiting on my shop manual and operators manual to arrive.

Yesterday I got the fuel tank re-installed with just me and a floor jack. Tossed a couple gallons of gas in, used the electric fuel pump to prime it, and it fired up! She's alive!!!
At first, it seemed like maybe the manual fuel pump might be bad since it would eventually die if I shut the electric pump off. But then at one point it did keep running for a good 5 minutes on just the mechanical pump. I backed it down the driveway and drove it back up to the garage.
But after a while it seemed I just couldn't keep it running. Maybe I need more gas in that tank for the pickup to really draw so I'll get more in there today.

Also, I think the linkage for the transfer case/reduction unit might need adjusting. I was fussing with it and sometimes shifting into Drive...the Jeep wouldn't move.
Anyone know if the Transfer Case has 2 or 3 settings?
Is Forward "Low Range" and Back "Neutral"?
Or is "Neutral" in the middle and I need to pull all the way back for normal driving operations?
And do I shift the reduction unit while in Park or Neutral of does it not matter?

Here's a pic of the tag on the firewall, maybe I need to find a decoder to tell me what it says?

Replace the filter in the electric pump, if its dirty it could restrict flow enough
that the mechanical pump can't pull fuel through.

Most transfercases are 2HI 4HI N 4Low. The Quadratrac may be different, I'm not sure.
Twin stick will have one lever for Hi and Low range, and another lever for 2wd and 4wd.

Looking back at the photos, looks like yours is Quadratrac, so I'm not sure,
I believe first step is AWD, next 4Loc then Neutral and finally 4Lo Loc
Do you have an owners manual? it will hold the answer, but I'm sure someone here will reply.
