Question regarding AC/Heater removal

[Lefkada]

I've found a thread or two regarding this question, but my setup is a bit different so I wanted to be sure before changing anything.

For removing (deleting) the entire AC/Heater assembly, can I plug both outlets (with a brass plug) at each arrow location in the photo?

Thank you!

Not until you replace some of that rubber fuel hose with steel! Grab a trans line from Schucks or something! Or better yet, any small block fuel line to get it close enough to the carb that you don't have so much rubber, particularly by the exhaust.

On the heater I'd say yes, with the only caveat being I've never had a vehicle with the setup that returned the heater flow to the rad instead of the water pump. Unless that serves some special purpose, and I can't imagine what, I'd think it's fine.

yes you can plug the heater hose outlets with a pipe plug

you could plug the lines, but it will let more coolant circulate, if you just connect the two points, along with the lines, there is no upper water pump line, do you have any overheating issues?
I second getting rid of the rubber fuel lines and replacing them with steel, the rubber lines like to leak, and then start fires. Where you have to have rubber lines, make sure you use fuel injection line, that is specifically make to hold to the chemicals in Fuel.

You should see some of the shoddy wiring and shortcuts that the previous owner put in! I'm tearing everything out.

I have not experienced any overheating issues since bringing home the truck on Saturday, so you think plugging the outlets would be fine rather than connecting the two outlets/inlets with a hose to continue circulation? I'm trying to clear out and simplify the engine bay as much as possible.

Yes, I'll definitely update all the hoses. We don't want any fires!

personally i would connect the two so coolant will still circulate, but if you want things out of the way, then just cap them

When every thing was stock and hooked up, when you turn on the AC it stops the circulation of water through the heater core so since you are abandoning everything just pull the nipples and put plugs in.

Why does it seem that everybody uses a rubber hose next to the header with that cheap a.. plastic .99c filter. Worry about that first before you burn your truck to the ground

Definitely. I'm pulling the motor this weekend to take the rest of the truck to the sandblaster. Will be buying motor components in the meantime.

The previous owner had mounted the electric fuel pump to the inside of the grill (???) and hung the power wire back up through the engine bay and shoved it into an occupied unit on the fuse box.

sounds like a lot of work, i'm glad you are doing it not me But we all know it will be work it in the end
