What is a reasonable repair time to fix the ever present problem of the
Vanagon Fuel tank leaking when filled up?

I assume the below parts will cover the repair. anyone have experience with
this?  Need to get a time estimate and any tips you may have.

N 901004.01  Grommet, Breather Lines to Top of Gas Tank (3 Required), 1980
to 1991  $1.75

251-201-311A  Valve, Vent for Gas Tank, 1980 to 1991  $21.66
