Enhance your diesel's fuel efficiency and performance and prevent major fuel system repair bills with a FASS Fuel System.

With the dramatic changes in fuel over the past several years, our vehicles are suffering in performance and efficiency. Talk to us to see how a FASS Fuel System can help turn that around for your truck!


Trucks are pushed to work much harder than the average vehicle by carrying heavy loads, pulling large trailers, and plowing snow. Routine maintenance is extremely vital to keep your truck up and running as well as saving you money over the long run.

During the winter months, we frequently have trucks towed into our shop with cold weather related issues!

1. Bad Batteries! Did you know that batteries lose 50% of their crank power on cold mornings?

2. Cracked Engine Blocks! This is due to improper coolant strength.

3. Dirty Fuel Filters! Not only do they not allow your truck to start, but they can cause major fuel injector repairs!!

Check Out Some Great Winter Tips: 

Check tire tread and inflation: Your car’s tires have to work harder in the winter with colder temperatures, salt and ice on the roads. Check your tire inflation to make sure there is enough air in your tires. The changing temperatures can cause the air molecules to contract or expand, changing your tire pressure.

Get your car’s brakes checked: This is probably the most important winter maintenance check. Your anti-lock brake system works overtime in the winter, so it’s important to ensure that it is running properly. If you notice any squeaking or grinding noises as you brake, if it becomes harder to brake (you have to push the pedal down more), or your car pulls to one side or the other while braking, you need to take your car in for a professional brake check from your trusted auto repair shop right away. 


Plug in Your Diesel: Plugging in your diesel engine using the block heater makes it start easier & run more smoothly when it's extremely cold. It keeps the engine block, coolants and oil warm. 

Do Not Underestimate Warm-Up Time: Giving your cold diesel engine time to warm up is essential. Before operating, you should always allow your equipment to warm up for at least five minutes – this will allow the hydraulic oil to warm. Failing to do so can make the engine work harder than necessary.

Water in the fuel of a diesel truck is a bad thing any time, especially in the winter: Your diesel fuel is constantly running through the engine bringing the fuel temperature up. This means your fuel tank is also very warm. When you park the truck and it cools down, moisture forms on the inside of the tank wherever there are bare surfaces that fuel is not touching. If you keep the tank full of fuel all the time, this prevents a great deal of water from getting in your fuel. This helps prevents injector problems which is very costly.

Keep ice off your windshield wipers: Before the next winter storm, put socks

on your truck or car windshield wipers to help extend their life. Also, stand up the wipers

to prevent them from sticking to your windshield and getting buried in snow and ice.

Hi, I’m Jim the tech guy here at Shenandoah Valley Diesel & I'd like to give you some tips on your Diesels. FASS Fuel System


If you own your own diesel you will soon find out the expense of replacing fuel related components. The newer the diesel engine, the closer tolerances you will have in the injection system components. The close tighter tolerances are needed due to the high pressures needed to atomize the fuel to make a cleaner burn in the combustion chamber. With lubricant being removed from diesel fuel to help protect the environment you now have created another huge problem and it has cost all of us.

Air bubbles in any fuel is not good because it cost you power and fuel mileage. Fuel sloshing around in the tank while you are moving the vehicle around cause’s air in the fuel. This fuel, (depending on your engine) is either sucked into the injection pump or is pushed by a transfer pump into your fuel injection system. The factory pumps, mechanical and electric pumps actually make air. Air was not as big of a problem until we got to the closer tolerances that we have now. Where there are air bubbles there is not as much lubrication to help protect the moving parts not to mention all the heat that builds up around the fuel system with a running engine. This is a recipe for disaster. Now add in the filtration systems that doesn’t filter the fuel down as far as it needs to be to get the debris out of the fuel, and you are headed into spending major money.
