While we are on gas caps, I have difficulty adding gas using the vapor recovery
nozzles. First the vapor bellows must be compressed or no gas will come out.
So I push the nozzle into the filler neck, this requires about 5-10 lbs of
push, any less and the pump shuts off. On new cars, there is a small gas
opening (sized for unleaded gas) the nozzle engages, rests on the neck and it
works nicely and automatically shuts off. With the Tiger, I push, and squeeze
the trigger. Sometimes gas flows down the side of the car. This is very
unwelcome. I have experimented with ways to hold the nozzle, push and trigger.
Sometimes I have good luck, otherwise I'm running for the windshield wiper in
the bath (when was the last time you saw a water hose in the island?) and wash
off the spill. Sometimes I think I have it just perfect, and gas comes out the
interface and down the car. Trying to fill a 1 gallon gas can is a real circus
act, one hand to pull the bellows back and the other !
on the
trigger.
Does anybody have any tricks for keeping the gas flowing and into the tank?
Mine is very difficult.
I buy only Exxon (Valero in California) and their nozzles don't work well with
my filler opening.
