Peaches 1980 J-10

Now the work begins.

I also noticed the round holes behind the grill. I would like to change out the grill to a center piece and add round headlights but info is needed on this modification swap, I'm a CJ guy.

OK got her running and the carb leaks/needs to be rebuilt.

for the round headlights and grill switch, the hardest part is finding it. All the FSJ grills are interchangeable with a minimum of modification. Just make sure you get all the pieces.

Thanks, a friend of mine found a chrome pig nose-he is bringing it by this week.

Put some premium in the tank (4 gallons) and got her running again. She idled for a long time then when the (somewhat) high idle released she started to die. The temp was at normal and after normal temp the oil pressure was 38psi idle. 40 cold. No leaks at the carb so I guess the seals swelled after sitting for so many years. Maybe I need to adjust the carb and go from there. More continued-stay tuned.

I put 4 gallons of premium in the tank and I'm sure some junk was in it. New filter and it ran until the high idle stepped down. I think the filter clogged after 25min of run time.

So I will drop the tank and swish it around w/the fuel in it and install a new sender.

1. Should I put some Stay-Bil in the tank to help loosen it or just swish it around w/the new fuel in it?

2. Does the J-10 have a circuit board for the gauges or wires like a regular Jeep?

3. If the circuit board is bad, where can I get a new one?

Thanks again,

I am looking to buy a sending unit for the Jeep and want to verify the ohm readings first.

Full ?
1/2 ?
Empty ?
