……. The more year pass, the more parts reach their envelope of life. In the case of our twin 25 gallon steel tanks can’t hold up to Ethanol laced fuels. Ethanol….alcohol and water separates in our steel tanks to cause rust to form clogging up your fuel filters. Fuel injected systems foul injectors and basically cause all sorts of problems.
When using the 2 steel tanks, Fuel injection systems have a complicated plumbing set up to pull from and put back into the same tank. We’ve tried many plumbing configurations, all being fabricated with aluminum, Ethanol is no problem
Another issue is our tanks being only 4 1/2″ deep tanks we have issues of running fuel injected system out of fuel pressure quick means your motor will shut off…..not great.
Unfortunately, the laws of physics tell us there’s no way any baffle system to stop this dangerous sloshing. Every tank we have produced is still on the road. Every tank has done a good job at pumping fuel in faster, properly venting such a large volume of fuel. AND the single container design simplifies fuel lime routing eliminating fuel solenoid valves. We add a second 3/8″ vent line on top and the fill too inputs at the top of the side unlike the original fill. Heck, after 1/4 full in those old tanks, the intake fuel has to push fuel out of the way pressurizing the tank making filling difficult.
Theres a pile more in the design of these tanks. these tanks than simply an aluminum enclosure. Late designs have a 1/2″ aluminum Crossmember support thru the tank.and mounting brackets welded to the tank. Improvements based on many miles of input from all those who have them. Thanks guys for helping us with this. One day this will be an important update….. Keep it in mind
Thanks for your support, we at the Co-op feel it important to keep our coach outfitted with new technologies ….that’s how they will stay out there.
Again, even our early tanks do their job, to stop the fuel slosh issue needs a fuel accumulator system like the FiTech ‘Forced Fuel” system. This hurries your hi pressure pump in a 1/2 gallon tank where fuel slosh is not a problem. All of our tank designs benefit using the forced fuel system. Google FiTech and look the system up.
All cranks and styles of fuel injections systems really need this accumulator system. No matter system you have, your fuel tanks are still only 4 1/2″ deep…..no way around it.
If you have one of our tanks or even using original tanks, the forced fuel system is the ticket.
If this is something you’re interested in, call the shop and get on the back order list. Bummer but they have become a key component in outfitting a GMC back to the road.
If you have other questions, give me a call………
