SPID question
Does the SPID contain dealer installed options or only Factory installed options? Looking at a SPID with option number INL210 Auxillary Fuel Tank.
Owner says the truck does not and never did have saddle tanks. |

Re: SPID question
I might be wrong but I am under the impression these are only factory installed options. If I am wrong other can chime in.

Re: SPID question
What year is the truck? I think that if it was a 72, GM had started putting aux tanks in, but years prior were farmed out to dealers or the aftermarket. SPID only lists options the vehicle left the factory with.

Re: SPID question
Saddle tanks were a dealer installed item. The 72 factory aux tank has a filler just like the one in the cab and it sits a little further back from it.

Re: SPID question
My '72 GMC has option "NL2--Auxiliary fuel tank" listed on the SPID.
And the filler is a tad over 1' aft of the front of the bed.

Re: SPID question
Could be a glove box off another truck also. Just a guess. If he say's it never did have them, then I would say it's been swaped.

Re: SPID question
more likely the bed was sapped.
The SPID is only what was installed on the assembly line. Sometimes there were mistakes made, but they were generally pretty acurate |

Dealer installed were put there by Colorado Customs out of Brookfield Colorado and there were fuel access doors or filler ports behind the wheel well

Re: SPID question
72 not original owner. VIN on SPID matches truck. When I get to see the truck I'll see if I can tell if the bed was swapped or tank removed and bed repaired as well as dash repaired where the switch was. I think a bed swap is most likely.
Anybody have a picture of the following: switch location, aux tank location underneath the truck, or any 70-72 medium gold poly truck, paint code 526? |

There is a "double valve" on the floor, between the seat & the driver's door that switches the fuel flow from 1 tank to the other. The reason I say "double valve" is, 1 part of the valve switches the gas from the tank to the fuel pump & the other part switches the fuel pump return line.
