RDS MFG INC 72775 Fuel Tank

I have a GMC 2500 HD that I use for towing a 35 foot fifth wheel travel trailer. I need the convenience of having an extra fuel supply to reduce the number of fuel stops and security of additional fuel for those long stretches of highways between fuel stops.I chose the RDS Fuel Tank Toolbox combo 40 gallon capacity model #72775 for the following reasons.Less fuel weight @ 40 gallons vs larger tanks, (8 pounds per gallon).This model has a 10" deep tool box compared to 6 ¼" on other models.Fits just below the bed rails in front of the internal fenders.Allows room for my 5th wheel hitch to operate properly.I received my RDS auxiliary fuel tank/tool box combo securely packaged in a cardboard box strapped to a wooden skid. The installation was simple and took approximately 1 hour to install both tank and fuel tank installation kit (GMC #3490902) that controls flow of diesel fuel from the auxiliary tank to factory tank. Additional time was required since I chose not to gravity feed the fuel. I added an inline filter (Fram from Wal-Mart) below the truck bed to the feed hose that was installed as part of the kit. The filter is connected to a Facet-Purolator FEP12SV Cube Universal Low-Pressure Solid-State Fuel Pump (4.0-7.0 PSI, 32 GPH) (purchased from [...]) which is connected to the control valve on the adapter supplied with the optional kit. The pump is controlled inside the cab to automatically fill the factory tank using an electric LED rocker switch purchased at Wal-Mart. The look of the tank is great. Not many people can tell it is a fuel tank. I found the tank to be very well constructed good welds and the fit and finish excellent. I would recommend this product to anyone requiring added fuel capacity in a diesel application.Additional Notes:When tank is positioned in truck bed, open lid and check back clearance.Check the tabs to see if they match up to the high ridges in the bed. If not, use flat washers as spacers.Pilot drill tank tabs from top, then drill from bottom for a straight centered hole.Place tank back into position and mark truck bed through the tab holes.Make sure there is no obstruction below bed of truck, then drill.Drill hole for shut off valve and fuel line, check for obstruction. I had a brace and had to offset the hole. To keep from kinking the hose, I had to make a loop then run through the drilled hole.Install the fuel pump below the bed to allow gravity feed to the pump.Run the electrical wire to a switch, then connect to power source with an inline fuse. Be sure to ground.(J.C. Whittney also carries the Facet Fuel pump)

It was the Duel purpose of the unit

Ok, I really like having the tank installed in the truck. Plenty of fuel capacity know and it will work well for hauling a 5th wheel trailer on long trips. So, the product and concept is really solid however, there was a real problem with shipping from the RDS factory. The shipment sat in Florida for 5 days. After I contacted the freight hauler (ABF) the dispatcher concluded it was on one of three possible trucks (either in Salt Lake City, on the way to SLC or in Atlanta Georgia). After 24 hours the ABF dispatcher was able to locate the tank and get it moving (she did a great job!). Once the shipment was transferred to Superior shipping it showed up at the door on time but damaged. The lid latch on the left side had been deformed and required modification by me before the lid would open or close, also there was cosmetic damage to the surface of the tank caused by abrasive rubbing with something. All in all, great product however, RDS could do a significantly better job packaging and shipping the product. I have written to RDS on their web site suggesting improvements with their processes; no response to date. Hope this helps someone in the future. Rating for the product would be a solid 4 without the above issues.

One day shipping!! Product as described!

The tank/toolbox combo is what I needed. I don't have any problems with the tank/box or the installation kit. The only problem I had was getting any valid communication from Nothern Tool or RDS. The tank was shipped directly from RDS and Northern was just a go between that got in the way. I never could get any valid shipping information from either. I finally got a call from the trucking company two days before it was delivered. The freight line needed to be sure that someone would be there to sign for it and be sure the delivery instructions were correct. I was in the dark about when it would ship and got two incorrect shipping/delivery dates from Amazon, Northern Tool and/or RDS. I don't know which was the problem, but there was a big problem communicating with this customer.

Amazon had the wrong description, i thought i was buying a 90 gallon and it was a 40 gallon tank.

Product damaged so bad can not open the fuel tank / tool box lid.I contacted the RV and Auto parts store who I purchased this from and explained it was inoperable. They promptly sent a new one and sent a RMA to have UPS pick up the damaged one. GREAT SERVICE!The reason for 4 stars instead of 5 is the actual toolbox seems a little flimsey allthough the fuel tank seems solid.Will be installing today.

Nice product, was damaged when it arrived, but the main thing is I ordered a 40 gallon and I can only get 30 gallons in it
