Yyesterday I had the Transfer Flow toolbox/aux. tank installed in the Silverado. It is a 30 gal. aux. tank. somewhat pricey when all said and done, but I think it will be worth it for our needs.

After picking up the TV from the shop, the aux. tank was empty and the OEM tank was half full, about 13 gallons. I didn't stop to fill up the aux. tank because I wanted to go to a gas station near the rv park where the diesel was at a good price, about 18 miles from the shop where I had the tank installed. My OEM gas gauge read a 1/2 tank and my new TRAC II for the Transfer Flow read 13 gallonms when I started out from install shop. By the time I had gone 5 miles, my OEM gauge read 1/4 tank and the TRAC II said 7 gallons. Needless to say, I was concerned knowing I had a 1/2 tank, and was wondering if the install was done correctly. When I filled up the OEM tank it took 12 1/2 gallons (have a 26 gal. tank) which was the correct amount of diesel I thought I needed. I filled up the 30 gal aux. tank to the full 30 gal.. I drove to the rv park a mile away without any change in gauges. This morning, I started the TV and WALLAH, the OEM read full on the OEM fuel gauge, and 26 gallons on the TRAC II readout. The aux. tank read 30 gals.. After driving 100 miles today, all gauges read correctly, including OEM range, fuel used, fuel gauge, as well as the TRAC II showed that I had used 5 gals of fuel, and had 22 gals in the OEM and 30 gals. in the aux. tank. So, needlesss to say, if you get the Transflow, give its computer enough time to figure out where it is at. I am very pleased with all of the readouts being correct, and am looking forward to going past all of the higher priced gas stations on the road. If you own a GMC product, the range gauge will only show range available from the OEM tank and not the combined range of both tanks. Hope this made sense.
