You do know they have ball valves in pvc that are much lighter and
work
better, don't you? <g> Much cheaper too. <vbg>

Yes but I don't know the long term effects of gasoline
on PVC. There are bronze valves with chrome balls
running in Teflon seats. Can't get much better than
that. Also $7 each is very cheap for an aircraft
part.

The Cole-Palmer website
http://www.coleparmer.com/techinfo/ChemCompResults.asp
rates PVC w/ unleaded gasoline as
Fair -- Moderate Effect, not recommended
for continuous use. Softening, loss of strength,
swelling may occur.
rating for leaded gasoline:
B = Good -- Minor Effect, slight corrosion
or discoloration.
I use a PVC tube for unleaded gasoline transfer. After one year of use
it is discolored. It is a gravity flow installation, so I do not know
if any loss of strength has occurred.
