dbossman prettymuch nailed it.
4 foot length of 1" CPVC pipe
2 end caps
1" threaded NPT female hose barb
1" threaded NPT male adapter for the barb
An old folder clip I had laying around to fasten it to the tank
1 black extra long twist tie to hook it to
1 can Krylon Fusion "satin" finish
1 can CPVC glue (used for PVC AND CPVC)
1 can PVC cleaner
1 roll teflon tape
1 hack saw or other method for cutting
1 3mm or SAE equivalent drill bit
1 ruler or tape measure
One afternoon to kill...that should sum it up I think.
