If you drive a diesel engine vehicle, you know how great they can be. The average diesel engine gets 45 miles to the gallon on the highway, and on a single tank of fuel a diesel engine can take you between 400 and 800 miles. For a variety of reasons, diesel engines are only now just catching up in the United States. Only one diesel engine car is sold out of every 100 in the United States, and only 10 out of every 100 trucks. For those in the know, diesel engines have everything going for them. If there’s anything that can improve your diesel engine and push it up another notch in power and reliability, it’s having the right diesel fuel pump. That’s what keeps FASS fuel system dealers so popular among the diesel community.
