when you top off your gas tank at the gas pump, does your '80-'87 vanagon
spew gas all out the filler neck and down the side of your van?

the 88-91 vanagons have a redesigned filler neck with a float ball at the
bottom, which prevents the gas from backwashing up the filler neck and out all
over the side of your van..
when you top off, the float ball rises with the level of gas and seals off
the filler neck so no gas can backwash up it.
  the 80-87 vanagons have no float ball. just an open hole into the tank.

i have added the late model 88-91 filler neck to my '84 sunroof van and my
'85 doublecab, and my 86 westy (since sold) which all had the fuel backing up
out the filler neck problem, and it solved the problem when i added the late
model filler neck.  no more mess, no more embarassment and hazard at the fuel
pump with a big puddle of gas on the ground, and no more sneakers soaked with
stinky gasoline that i had to smell for the rest of the drive :<).

this is a big improvement..especially everytime i travel in NJ, where you
cannot pump your own gas, and the tank monkeys like to shove every last drop into
your tank that they can..

its a direct replacement..easy install.. just remove the 3 phillips screws at
the top of the neck ring, and then turn the round plastic filler neck trim
piece about an inch either clockwise or counterclockwise (its held into the body
with "teeth") to unlock it, and the whole filler neck just slides out of the
tank.

i have 2 of these late model filler necks with float balls, if anyone is
interested, p-mail me..
