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.

There is a way to make most of this problem go away. I have been using the FASS Fuel System along with selling and installing it for years now. Best money you will ever spend for your diesel. These pumps take air out of the fuel and also filter the fuel so much better. These systems are awesome. We are a dealer for them. You can call me any time to chat about these systems.

Truck, Auto & RV Tune-Up

Spring/Summer Maintenance

Even though is seems like winter is never going to end, the long, hot days of summer are just around the corner. Trucks are pushed to work much harder than the average vehicle by carrying heavy loads and pulling large trailers. 


1. Tire Pressure!

Running the correct tire pressure is always extremely important but even more so in the summer months with the relentless heat of summer.  Everyone knows your tires get hot in the summer but they can easily reach explosive temperatures if they are under inflated or over inflated; we are all familiar with the gators on the freeways.  Excessive speed and weight also contribute to high tire temperatures.  Assuming no injuries occur during a tire explosion, they almost always cause collateral damage, sometimes very expensive damage.

2. Batteries!

These very important items are often overlooked during the summer because cold weather starting problems typically don’t exist.  However, hot weather is more damaging to your batteries than cold weather and weak batteries can fail during excessive heat.  It is important to make sure the batteries are accepting a full charge and the electrolyte levels are full.  Clean your battery terminals and wire ends while you are checking your batteries.

3. Air Conditioners!

Check your air conditioner for proper operation and if necessary have the system pressure tested to check for leaks.  Fix any items that are leaking such as Schrader valves or cracked hoses and recharge your system as needed. You’ll be happy you did when the thermometer hits the 90s and above.

4. Windshield Wipers and Window Washer Fluid!

Sometimes these items can be overlooked or you may decide to put them off until fall because we are entering good weather driving. Windshield wipers in good condition and plenty of washer fluid are very important in summer for those frequent rains you will encounter and when you pass through the swarm of flying insects  in your path.  Not enough fluid or wipers that smear will cause decreased visibility which is a safety hazard. 


5. Coolant and Coolant Hoses!

It is so important to ensure your antifreeze is in good condition and ready to handle the demands of summer driving.  In addition to the actual antifreeze, it is important to inspect all coolant hoses. It is far cheaper than a breakdown and tow bill, or worse yet, an overheated and blown engine.

6. Engine Belts

Inspect all belts and replace any that show signs of wear such as cracks on the inside surface.  You might not think about your belts very often, but without them your day is over.
