[C320-list] hose barbs

[Jon Vez]

I've used a hair dryer with decent results. You have to be patient and keep
the dryer on the hose end for several minutes. I've also found glycerin much
more effective than dish soap--put it liberally on the barbs. This is the
stuff that comes with your impellers--you can buy it at your local CVS or
Walgreens in little packets--hose connections are probably my least favorite
boat project....

Good luck...

I've used a heat gun to make connections on various hoses and fittings.
Works fine.... just don't overdo it on the white hose.
