A few months ago I had my '90 Vanagon's fuel tank replaced ($650) because it had sucked itself into a crumpled and leaky shape. Some part of the system was malfunctioning in a way that put a powerful vacuum on the tank. It just started doing it again this week - I can hear the tank going "poing" as it deforms inward, and there's a "whoosh" when I open the gas cap. Any clues as to where the failure might be? Is the cap supposed to be vented? (and it's plugged now?) Where else is there pressure-equalization in the system? I'd prefer not to have to replace the tank again... bcnu - Grungy (John Gladu) (Houston, TX) grungy@mindless.com '60 dddPanel walk-thru / '90 Vanagon / '68 & '69 Bugs / '93 Eurovan |
