Talking What's up people! 1980 J20 Jeep

So I have a 1980 J20 Jeep with a AMC 360 currently on propane that I am going to be converting back to gas and am looking forward to letting you guys know how my restoration goes with my true love. I am currently living in an apartment so repairs are difficult, i deal with a lot of obstacles and planning needed to accomplish a goal considering my work space and no prior mechanical training but someone has to do it right!

Don't have a clue about going back to gasoline from a previous LPG conversion. A local RV shop can prolly guide you toward an info source. So far a being new to wrenching I highly recommend you spring for an original 1980 TSM (factory Tech Service Manual) or a repop. Don't bother with a generic Haynes manual. They try to cover too many years to be of value for 80 specific specs. On he apartment dwelling thing I would source a friend or relative with a house/driveway and work a deal.

Welcome! No better way to gain mechanical skills than to work on a Jeep.... you know, 'cause they never stop needing something!
That's how I learned!

Welcome to the forums! I concur to getting a factory TSM for your year, it will help a lot.

I have done a few conversions to and from propane, granted none of them were on jeeps, but all carb engines are very similar. Most were strait forward from LPG back to gas... Just remove the propane tank (after its emptied of course) and the lines/fittings/ect. The motor side was just as simple as replacing the LPG carb with a gas carb, installing either the mechanical fuel pump on the block or an electric pump, installing a factory tank with sender/pickup in the stock location and running 2 fuel lines and 1 wire for the sender. That was on '77 ford f100... A bit more complicated going from gas to LPG...

An ECM controlled motor, well thats a different story... quite complicated...
