It lasted 112,000 miles and 8 years.However,I haven't used it for switching between tanks until the last couple years because the rear tanks pickup was rusted and never worked.I replaced it with a NOS pickup and started using the tank for a couple years.I kept getting plastic filings in my electric fuel pump screen and had to constantly wash it out.Evidently the new poly tank had a lot of shavings in it and should of been rinsed out before use.Anyway,I suspect these shavings plugged the port.Rather than frig with trying to clean it,I just grabbed another one.I didn't want to take too many showers experimenting lol.Anyway,for 70 bucks if she goes another 100k,it will be worth it again.Though not much fun changing,it only took a few mins.
I dunno if I'll have this truck for another 100k though.It should be an F450 too.I certainly use it like one.
At some point,I really should build up another F450,probably making use of a lot of chip trucks current parts.I dunno.Maybe I'll just keep running her into the ground.She doesn't owe me anything at this point.
