Help gas tank draining question

[Ghost-Flame]

I'm cleaning and sealing my tank. Using the POR-15, everything is going well so far. I am at the point where I need to get the tank completely drained and bone dry. There's about a pint's worth of water in there that I can't drain through the pet-cock. I have the petcock out and it appears that there is a plastic sleeve lining the petcock hole. does that sleeve extend up into the tank and act as a stand pipe so you don't completely drain all the sludge into your fuel line? If so can I remove it and get another one after I seal the tank? Is it even necessary if I have cleaned the tank and sealed the inside?

I found the oem parts diagram on bike ***dit .com I see the screen stands up about 3.5 inches inside the tank. I was able to get it out with my dental pick and needle-nose pliers. I still have a little maybe an ounce in there. I'm wondering if this little bit that can't be gotten out, will that little bit cause puddling when I do the POR-15 sealer? I have a heat gun for drying the moisture. They say not to use a heat gun on the sealer because it is combustible... wait a minute that could be fun!

My guess is that it is there to act as the stop-valve for the regular tank:  when the regular tank goes "empty", you have to switch to Reserve to finish draining it.  Anyway, I would suggest using compressed air to dry out the tank.  Just spray air into it until it is completely dry.  I used this technique to dry circuit boards, many years ago:  they had many, sharp, short component legs on them, each of which could tear your skin if you brushed against them; compressed air dried the boards quickly, efficiently, and with little effort.  Quick drying was necessary to avoid oxidation of the board's circuit traces.  Cheers!

Okay, I edited my above post. That plastic thing is a screen that extends up in there about 3.5 inches. Now I'm concerned about the sealer which is some kind of space age, flexible plastic that you coat the inside with by pouring the sealer in and tumbling the tank for about 30 minutes. Then you are to drain off the excess. that screen was causing a problem but now, with screen out there is still about  1 ounce of rinse water in there, that's not a problem with either compressed air or a heat gun. POR-15 warns not to allow excess to remain because if it puddles it won't cure right and cause the sealer to fail.

That sounds like the fuel filter armature (the screen is the OEM fuel filter), attached to the petcock assembly.  Remove the petcock assembly before sealing the tank, as the sealant may seal the petcock to the tank!  Cheers!

Just keep turning it, and it will not puddle.
