Rear heater lines layout

[cims1970fj40]

Hi,
I’m running a rear heater in my 74 FJ40 and wanted to know if the rear heater lines are in the correct position before I put my gas tank back in. Also I want to make sure that the clip that is circled in the picture that attaches to the side of the transmission hump is in the correct position or if I need to flip it around. Any help would be great.

Thanks,
Cimarron

mine has that bracket flipped 180 and I think you are missing a hold down clamp that attaches to the bolt where the fuel lines come up through the tub.
mine has a clamp there that holds the lines close the floor on the driver side of the fuel grommet.
just took a look at the clearance between the tank and the lower hard line and it barely exists. the forward vertical edge of the tank pushes into the foam a bit

I dont recall where I got these pictures from. I hope they help. I think a really good thread someone did possibly named 1977 Fj40 build?? I think it was @SSCR build thread. Look for it it is a great resource.

FWIW, before you put down the tranny tunnel for the final time you may want to make sure it is sealed well. A lot of hot air can come through it. I put a light in the cab and got under the truck to see where my leaks were. That was after everything was put back together and it was harder to seal them. It would be easy to run a self adhesive seal all the way around now while it is apart.

I think you'll want to tuck the lines in more next to the tank cover. Route lines below the second clamp hole.


I don't have your circled clamp, PO had the trans cover Rhino lined. I musta missed hogging that hole out..

Do you have the grey firewall cover for heater lines?

For those wondering, that is factory 1976 foam covering the lines.

Are your soft lines long enough to run on the floor? I measured mine at 26 1/2".

I routed soft lines on the floor as much as possible. Didn't want the suspended in mid air in case something gets dropped between the seats. Guess you'd consider that strain relief for the rear heater nipples

Here you can see my fuel tank lip. So the hard lines route just a bit above the tranny hump flange that gets bolted down.

Thats a good point I didn’t think about. Thanks for the tip. There was a few areas that wasn’t as snug as I would like it to be. Thanks

Thanks for the additional photos and remarks. That should help a lot.
