Stout Posted November 3, 2021 Share Posted November 3, 2021 Just brought home a ‘73 1210 pickup, and am doing some wiring cleanup to track down a parasitic drain. I don’t have an owners manual (yet), and am wondering which tank is considered the main and which is the aux? I’m ASSuming the one with the filler neck behind the passenger door is the main, and the filler neck behind the right front wheel is the aux - but wanted confirmation before buttoning up this part of the wiring. Thanks in advance. Quote Link to comment Share on other sites More sharing options...
Administrators Moses Ludel Posted November 8, 2021 Administrators Share Posted November 8, 2021 I believe you've got it right. On a conventional cab, the OEM main tank filler is behind the passenger door just below the bed sill level. The filler at the right front fender is auxiliary. The arrangement can easily lead to confusion. However, models without the auxiliary tank have only the filler behind the passenger door. If this were a Crew cab, the layout would be different.
