'87 GMC High Sierra Aux. Tank Problems

Mar 29, 2005 1 Replies

Not a Chevy, but is a General Motors Vehicle. My '87 GMC High Sierra will no longer switch from one fuel tank to the other. I've replaced the switch but still no go. Anyone have any ideas where to start?



Direct emails are welcome. Thanks.


Sorry it's a 1985 not 1987
