What year did has tank move from underneath seat to back of jeep ???
 
I think it was around 1969. I have owned a 68 that had it under the seat. It even could have been 70 but I think 69. I am sure that someone on here can give you the exact date/day it was produced. So hang on.

I have a 69 it was under seat but PO moved it to rear of jeep and I am
Looking at buying new tub and owner is saying it is 69 but has no cut out for gas tank under seat
 
I thought that was another one of the 1976 changes but I have been known to be wrong:rolleyes:
 
I believe it was in '74. I've got a '73 and it's under the driver's seat.

That wouldn't be original then, '70 and newer were under the rear, switched when AMC took control of jeep.

That should be right. My 73 was in the rear and a wheeling buddies 71 is in the rear as well.

They had a tendency around here to rot out at after 6-7 years due to the foam pad between the tank and skid pan. The under the seat tanks were cheaper than the rear tank, so some people replaced the rear tank to under the seat. The indent was still in the body tub and was easily cut out during the swap making it look factory.

Good to know. I guess that's just one more thing that has been changed on my '73.
 
The tank was still under the seat in 1970.The change came in '71 models.
 
yes however some aftermaket tanks will be put back into the so called original place
 
what year would these be?

what year would these be?
I would say that was shot in about 1974.
How do I know?
The hood graphics?
The solid tailgate?
The roll bar?
No. It's the hair doo and the bright pink hot suit.

They are '71's.71 renegades have rear mounted tank,charcoal painted hood blister,a roman numeral ll at the end of the Renegade hoodstripe,and american racing alloy wheels.1971 was also the last year where the front fender well back edge ends right at the edge of the body tub.In '72 they stretched the wheelbase a couple inches and added a couple inches to the rear bottom of the front fenders.'72 up renegades dont have roman numerals on the hood stripes either.'70 renegades are nearly identical to '71s except they have a roman numeral l after Renegade ,underseat fuel tank,the hood blister isnt painted,and they had kelsey hayes steel wheels.

Bob, you have much more sound reasoning than me. But I am still confused by the dash and the steering wheel. And others on this site have said that all the CJs in 71 had the tank under the seat. Actually, I'm not sure they are 100% correct. I am wondering if the tank was in either place. Could it be that the high capacity tanks (21 gallons) were in the rear and if you went with the small tank it was under the seat?
I don't know. I just see conflicting information.

What about the dash and steering wheel?They look right to me.This is obviously a new vehicle promo shot and you can clearly see that there is no underseat tank.You can clearly see from the front fenders that dont have the extra 2" at the bottom rear that the jeeps cannot be newer than'71.You can clearly see the 'v6' emblems so they cant be newer than '71 since there was no 'v6' after '71.They have the correct wheels,stripes,and painted hood blister for a '71 Renegade ll,and they arent correct for a '70 Renegade l.Since its obvious from the wheelbase and 'v6 badging' its no newer than '71 and since you can clearly see it doesn't have an underseat gastank its pretty clear that anyone who says 'all '71s had underseat tanks' are wrong.I'm sure someone on the web has posted original sales literature that you could look at.If the jeeps shown weren't Renegade package equipped it wouldnt have been so easy to spot the year but the short nose making it '71 or older and no side fuel filler would still have narrowed it down pretty quick.If there were '70s with rear tanks or '71s with underseat tanks I cant find a period picture of one.

Bob, you obviously know jeeps.

Nomad127 has a '73 with the gas under the seat. That's why I thought some may had the tank under the seat and some (maybe with oversized tanks) were in the back.
I don't know. I am just trying to figure it all out.

BTW here's the site that has that picture:

Well the bodytubs and seatframes are the same through the 1975 model year so its real easy to put the underseat tank in a '71-'75 and many people have done it as an auxillary.I've even seen where people opened up the passengerside under seat toolbox area and put a tank under that seat too.Makes for the ability to carry a lot of gas when going into a remote area without having a bunch of gas cans strapped on everywhere,especially with the '71 up rear tank still in place.I'm sure some people when they ripped a hole in the rear tank just took it out ,cut a hole for the filler,and stuck the underseat tank from the 'old jeep behind the barn' in and kept rolling.Its not unusual to find tubs swapped around either.If you had 4 bare and original CJ5 body tubs from '55-'75 laying on the ground,without frames,steering columns,wiring ,windshields,or pedals and you asked me to identify them oldest to newest it would be a challenge because they are very similar and you could easily make any of them work.Holes or lack of holes are about the only differences on bare tubs.Looking at factory photos and ads ive never seen a '70 that doesn't have an underseat tank or a '71 that does.It wouldn't surprise me if some dealers in '71-'75 put the underseat tanks in as an auxillary since it is so easy to do.
 
You know, that might be a good idea. I have a pair of Fiberglass underseat CJ tanks sitting out here in perfect shape. I've been saving them for that unrealized project we all have in mind. I should install one of them under my drivers seat. The other might go under the offroad trailer I've been threatening to build for the last few years.
 
Did you guys notice that the pic you are discussing is from, and is labeled as, a 1955 CJ picture? Not saying that is what they are, just the title of the page and pic.

Edit: I found the same pic listed as a '71 reference...about 3/4 the way down...
The Jeep® 462, Renegade I and Renegade II Package « Earlycj5.com

and according to this page The Early CJ-5 and CJ-6 Spotters’ Guide « Earlycj5.com the fuel tank was moved in '72, as noted on this thread a few times. :)

Actually according to the page you linked it on two occassions states that the tanks were moved to the rear 'sometime in 1970' and under the '72-'75 section notes that all '72 up had rear mounted tanks but since they were moved 'sometime in 1970' that means that 'all '71 models' would have rear mount tanks also and some 'made' in 1970 would have also [although those made in 1970 could have been made for the '71 model year]I will concede some late '70 model year jeeps could have had rear tanks since the sales photos would only reflect early production.
