Keep Your Fuel System in Top Shape

Dear Partners of ROUSH CleanTech,
Todd Mouw, VP of sales and marketing, ROUSH CleanTech

The propane autogas fuel used in our vehicles helps reduce emissions, which can lead to lower operating costs and longer engine life. But, just like with any vehicle, regular maintenance is key to its best operation. Here are some recent questions we’ve received that will help you keep your vehicle’s propane autogas system running smoothly.

What items need to be checked at the 50,000-mile interval for supply line filter replacement?

The fill and supply line filters need to be changed at the 50,000-mile check. If you’ve had a filling issue prior to 50,000 miles, refer to the service manual on our website to help determine why this is happening.

How do you prevent seizing the tank cover plate bolts?

The supply and return valves are protected by a tank cover plate. To prevent seizing in corrosive environments, remove the tank cover plate screws. Then, clean the threads, apply an anti-seize lubricant to the threads and reinstall the screws. The anti-seize lubricant also will provide protection against rust, corrosion and galling. If seizing has already occurred, it may be difficult to remove the screws. Use of penetrating oil can help break them loose. This should be performed annually along with other preventative maintenance.

Is there any maintenance for the tank valves?

To keep the manual shutoff valve and bleeder valve moving freely, clean the threads, then close and open the valve. This will keep the threads easy to turn, and will prevent difficult operation in the future.

If you have any questions about the upkeep of your propane autogas system, call us at 800.59.ROUSH or visit the service page on our website. Thanks for partnering with ROUSH CleanTech.
