The Stovebolt Site Forums The Shop Area General Truck Talk Cowl drain tube

Anyone have any experience with the aftermarket drain hose . I tried putting one in and it seemed to big on the outside diameter so I thought it was a heater hose and left it .looked on my parts receipt and it was on there .so I will have to find were I stored it to try again but thought I would ask before I find it and give it another try.

I cut a piece of 5/8" heater hose and stuck it right on there.

I had trouble getting my aftermarket drain hose installed to the tube inside but with a little pursuasion and some verbal abuse I was able to get it installed.

Wondering if anyone has developed an extension to get the drain to clear the engine rather than existing above the engine.

I think some have extended the tube below the top of the valve cover. The factory installation had the end of the tube off to one side, not directly above the valve cover.

I also just stuck some 5/8" heater hose on mine and routed it down the side of the engine. Forgot all about it until I saw this thread! When I got the truck it had been pouring water for 20 years all over the back of the engine, although honestly I'm not sure it really hurt anything in the end. But now I have a distributor back there so... it's a little more important if I get it caught outside in a rainstorm.

But now that I remember that, I should have a look as it is probably deteriorated inside the cowl!!

There's nothing to develop. Just get a long enough piece of 5/8" heater hose and route it all the way back to the tailpipe if you want. Use plumbing elbows or 45s to change direction if you don't want a single piece of hose.

Thanks for the replies just have to find the hose and get it done

My aftermarket one popped right on easy. It was very flexible.

The only way water is going to reach that hose is if you have the vent open, unless your vent seal is leaking.
I have all mine installed on an angle to miss the valve cover.

FWIW, I have a piece of 3/4 black rubber (the good stuff) garden hose on mine to clear the engine and hang down.

Figured it out ,I was trying to put my mgb heater hose on as the drain

Don't use English heater hose. It'll hang down on the wrong side of the engine.

Ended up realizing that when I ordered the hose it was out of stock so ended up getting hose from hardware store 1.99 per foot fits good through the firewall.

I don't know about the angle of the AD trucks but with my '37 I used some 1/2" sprinkler system Poly. Cut off a good length and use a propane or MAP torch to make a couple of quick passes over the end to soften it up and it will stretch on when inserted and cool in place. The natural curve from being in a coil helped with the angle I wanted, but a quick flash of the torch and it will conform to what you want, just don't overheat. it only need a quick pass. Trim to whatever you want for length. BTW heat works great when using poly for its intended purpose installing on the sprinkler system barbs...
