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. You don’t have to purchase from us. I will still help you as much as possible. We are very busy, but we try to take time for everyone.

I will have good tips on the site from time to time. I’m sure you will find many things that will help you with your diesel.

Fall/Winter Maintenance

 Fall is upon us with winter close by. Trucks are pushed to work much harder than the average vehicle by carrying loads and pulling trailers.

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?

  • Get your battery tested.

  • Check and clean connections.

  • Drive your Car...Driving your car keeps a charge in your battery.


2. Cracked Engine Blocks!

This is due to improper coolant strength.

  • For most areas, you'll need a 50-50 mix of coolant to water.

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: 

1.  Windshields                                                                                                                                

Before the next winter storm, put socks on your 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.

2. Keep Your Tank Full                                                                                                               

 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.

3. Plug It In                                                                                                                                     

 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. 

4. 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.
