My Landcruiser mostly sits idle these days, but occasionally I really need it. I leave the tank full and add “Stabil” type fuel treatment to avoid gummy deposits. Recently I found the filler cap cover pried open. It is an anti-siphon system but the gas gauge showed “empty,” so I thought they had found a way around that. I drove to the nearest gas station and added another generous dose of Stabil, but when I started to fill it the pump clicked off immediately. My tank was still full and but gas gauge has failed.
Since then it runs reasonably well, except that when I stop the engine dies and will not restart for about ten minutes. This makes me unpopular at intersections!
So what is the problem? It might be that I now have way too much fuel treatment for the volume of fuel, or perhaps overfilling the tank is somehow to blame. I tried removing the gas cap in case pressure in the tank was a problem, but nothing changed.
My intention now is to drain about half the fuel and then refill with fresh gas. And while I do not believe this is the problem, it seems like a great time for a fresh fuel filter and plugs.
As I write this it occurs to me that I cannot rule out the possibility that somebody ADDED something to my gas. I have driven it four miles since then and performance did not seem to change, but who knows? I don’t think I have any enemies but cannot rule out random vandalism.
Any thoughts? cheers, Flag Rich
