99 4runner- what are these leaking rusted lines?

[hawkcharmer]

Today I noticed a small drop on the ground. I thought it may be oil, but it turns out to be coming from one of these two lines that are (between frame and exhaust under passenger front door) and they are rusted beyond belief. The leaky line has holes in two places and is leaking red fluid. I think I should replace both lines...?

Does anyone know which lines these are and have any part numbers and threads
related to this fix?

Any feedback is greatly apprecited!

Thank you

Rear heater lines?
You losing antifreeze? Toyota has them in stainless now, or pm me I have a nice set from part out availible

Those go to the rear heater. Go check your coolant level hopefully you haven't lost much. You should replace as soon as possible.

rear heater lines.

you can replace them with rubber fuel rated hose and never worry about rusting.
that's what I did anyways..

I bypassed mine until I have time to deal with. I think my 96 parts truck has stainless.

Thank guys!!! I ended up bypassing rear heater for now. I'll replace with the rubber fuel line eventually.. Didn't lose much coolant

Has anyone swapped these lines for stainless? Any part #'S?

One of mine was leaking & my mechanic changed it out last year without telling me (til the other day) or charging me. Gotta love 'em.
