Re: WIW: GM Auxiliary Fuel Tank 2004 Suburban
It was mounted above the spare tire. So, I assume it is a gravity feed system. The filler neck is a one hole filler that splits into two fill hoses. Both tanks had the plastic GM cover to protect from minor impacts/penetrations. I found that in 01 or 02 they had an auxiliary tank with RPO code NGY, I think. I think it was 20 gals. This BURB was C2500 8.1L with what looks like steel security bars behind the rear seat and all glass areas, but the glove box was gone so I can't identify the stuff correctly. Thanks for the interest! Dan

Every 3/4 ton suburban from 01-06 that I've seen had that dual tank set up. I regularly work on 3 of them.
I have no idea on the value of them. |
