Technical Radiator Overflow from Fire Extinguisher

I bought this old brass fire extinguisher at a swap meet and want to make a radiator overflow bottle out of it. Has anyone used this type of extinguisher to do this? If so how did you get it apart to remove the pump inside. I plan to run the lines through the fill plug. If you made one please post it up and give me some pointers on what you did. Thanks Brian.

 

Looks like it may be soldered together.

 

It looks so much more complicated than an old beer can....

 

Here's my radiator overflow story about my Dad who was a 40 year Midget car owner. Drivers never look at the gauges, myself included unless the yellow comes out, all the engines were water cooled, mud stops airflow, gets hot, pumps water out, hurts the motor. He ran a very small dia. line T'd off the line to the overflow tank aimed at the drivers foot, a Very effective way to get drivers attention, worked, sometimes made a driver unhappy. I was smarter as a driver, in my cars I put idiot lights for high temp and low oil pressure, no hot foot for me. Remember a driver bitchin about this and Dad's reply, what's the problem, you're a hot shoe aren't you ? We all drank some beer, all was good, that driver drove Dad's car many times.

 

Use a propane torch to unsolder the top from the case.

 

You look at the gauges when you step on the throttle and it's down in power.

 

My dad cleaned one out (that Carbontech is nasty shit) and gave it to me for a squirt gun. It was a super soaker before such a thing ever existed.

 

Here’s what I did . Left the pump inside , sealed the top , and the bottom …. As you can see ran lines outside . Maybe there’s a better idea , but this works ….

 

Yup.....I did one. Unsoldered the top, gutted it to the point that I could keep that "T" handle on it, and re-soldered the top back on. Drilled a small breather hole in the fill plug, and drilled & tapped the discharge nozzle for an 1/8" pipe fitting with a 5/16" barbed hose fitting on it. Mounted it with the barbed fitting facing down. That way, it filled from the bottom, and drew out the bottom, just like a modern recovery tank.

You're right about the Carbontet being nasty stuff, but it sure does clean greasy parts fast.
