Carb and heater question

[cplus]

This might be a dumb question but I am in the middle of fixing and removing a few things in the engine bay while the engine was built and am wondering about removing the carb heater water line and the whole hoses and adapters for the heater. I just thought it would eliminete alot of clutter in the bay and I don't see using the heater at all. I would of course save the important pipes but they all seem easy the replace if lost. Some are rusted pretty bad anyway. I am repainting the bay so I am sure I could find some rubber plugs for the firewall holes. I have some rust to repair by the heater intake on the firewall also. Any input or feelings about it would be nice to hear. Thanks guys..

Well, not sure where you're going with this, but all I know is that when I was driving my car a few weeks back, that heater was nice.

Well I live in Florida and will be driving the car for kicks mainley, I have 9 vehicles. All the heater hoses looked terible, one was orange.. The engine is ready to go in and looks great, just wanted to replace or remove junky looking stuff. The car will never be original, front & back fenders were replaced with fiberglass kit before I got it. Just didn't want to screw something up. I would never think about it if I didn't think I would use it.

Jim, Removing and or disconnecting the carb heater system is a common thing thats done, if one lives in a warm climate. There should be no ill effects from disabling it. Just remember to let your baby warm up before driving off. I'm with you on eliminating under the hood clutter...I've eliminated the carb heating system on my 1970 too. Infact, I've revised the cabin heater lines so they look cleaner...the stock lines just looked a bit cheesey to me.

Did you custum fit hoses?? Never thought of that...

Like many English cars of the '60s and '70s, I strongly suspect that the 240Z heater was not standard equipment in much of the rest of the world, only in the US. (Every tried to find an early wiring diagram that shows the heater fan wiring?) So I see no reason why you shouldn't remove it if you don't need it. Fewer hoses means fewer things to go wrong.

Jim,

If you remove the steel coolant line that connects the two manifolds, and it's still usable, I'll gladly buy it from you. I've been looking for one and the only way I can buy one is if I buy the intake manifolds also. Let me know, thanks.

Jim, What I did was..........I replaced the lower radiator hose casting, on the block, to the later version with a threaded hole for a fitting, as opposed to the early unit you just push the heater hose onto. Purchased a nice AN fitting, some stainless steel 1/2" tubing, and the appropriate nut and sleeve for the tubing. I bent the tubing to run next to the block and used the two existing small threaded holes, on the side of the block, and secured it with Adel clamps. At the back end of the tubing I added a bend that would match the bend of a stock heater hose. I did shorten the end of the hose some. As it turned out, it is a much cleaner install than the stock stuff. Wish I had a picture to post but, if you look at my photo gallery you will at least get an idea of the work I do...just no picture of the modified hearter line!

Tom,

Which later model has a screw in heater hose fitting on the lower rad hose connector? I am looking to change this eye soar to AN fittings and Aeroquip hose. I was ready to cut and weld a male AN fitting but would rather purchase a connector and fitting adapter if I can.

The L28 from the 1983 280ZX-NA had it, don't know about other ZXs.

[sblake01]

My 78 has it which could mean that all L28s have that connector.

I will let you know Bruce.
