Fuel tank & water

Well, that was easy.

I got hold of some Kolor Kut and smeared it on the end of a flexible fiberglass driveway marking stick.

Pushed the stick into the tank until it went 'klunk' against the bottom. Pulled it out and checked for color change. There was none.

Just to be certain the stuff works, I ran some water over the end of it after testing the tank, and it immediately turned red where ever the water made contact.

Guess I can move on to my next worry.

Darn it. I really wanted you to take the plug out

So did I, misery loves company!

I wish I had known about this product before. Dick Egler has provided a public service by telling us about Kolor Kut.

Every gas station uses that water finding paste on the end of the dip sticks for dipping every day. They would probably smear some of it on the end of your stick if you asked nicely.

I had a Bluebird Wanderlodge that had a sump about 8"x8"x4" deep with a petcock that was protected from getting crunched. I would take a sample every 6 months and get a teaspoon of water and some dirt in a glass jar. Our 4106 has a hex pipe plug that has no evidence of ever had a wrench on it. Was thinking it might crinkle the bottom of the sheet metal tank and be a problem. So I had a small Summit Racing diesel 12 VDC pump and I made up a piece of fuel line with a weight on it and dropped it in, turned on the pump and pumped out two gallons of fuel. No dirt or water present. I changed the fuel filters and with my filter cutter cut the cans off both and there was nothing, no dirt or algae between the pleats of filter media.

GM tank is very robust in that area. You aren't going to crinkle the tank; maybe in an Eagle or MCI lol. The plug should be brass, so that it is not difficult to remove.
