Default Need identification on some lines

Can anyone help me identify what these lines are and what they’re supposed connect you, the run from under the engine somewhere on the passenger side, into the engine bay where they aren’t connected to anything, what are they and what are they supposed to connect to

Yah it’s difficult to see what I’m talking about in the pic but it comes from under the engine around the fuel pump area I believe, goes under the cross member and comes back up I’ve highlighted the lines in these pics with red


first pic shows how it goes under the cross member and second pic shows where it comes up out from under the crossmember

Those flared nuts with rubber hoses with screw clamps gives its identify and former application away. Is your car a four-speed? Then, a former owner changed it from automatic to four-speed which would be pretty screwy by bubba.

Well those cars that shift themselves have 2 lines going from the automatic gearbox to the right hand side, (passenger side) of the radiator. Automatic transmission fluid flows through these lines to be cooled by a special chamber in the radiator. If these lines are cut you will lose all your transmission fluid very quickly and your car will no longer move.
And a very expensive bill at the automatic transmission shop will follow.
Best thing to do with these lines is remove them along with the automatic transmission and install a real gearbox, bellhousing, clutch, shifter and all other necessary parts to make this a fun car to drive.
As apposed to a car that drives you around.

If you are going to replace those rubber hoses make sure the new hose is ATF rated.
Do NOT use regular Worm Gear style hose clamps.
The correct style camp for this application is Type "G"
Auveco part number #15862 is a good replacement clamp.
Also works on the non pressure power steering return hose.

Just curious, you haven't and are not driving this car right? If you are, then these lines have to be plugged in some manner or it would be like another poster said, all the tranny fluid will come out in short order and burn up the transmission.

no I’m not driving the car, it’s been sitting since about 97 just wanted to know what it was so that way I know what needs to get put in before any real damage is done

What is the reasoning against worm gear clamps and is it specific to certain applications?
