The best way to prevent issues like these is by regularly cleaning your fuel lubricators.

What To Do Before You Clean

Diesel Fuel Lubricators

You will often see that diesel fuel lubricators are dirty, and if you don’t clean them properly, they won’t do their job. Before you start cleaning your fuel lubricators, make sure to remove any dirt or residue from the bottom of the tank first. This includes the filter and other parts that are in the way of removing dirt from the bottom of the tank. Once those pieces have been removed, it’s time to focus on getting rid of all the dirt stuck on your fuel lubricator. If you want to clean your fuel lubricator quickly and effectively, take out a piece of cloth and dip it in some acetone or alcohol. Then use this cloth to wipe down your fuel lubricator with a firm motion until it is no longer dirty.

How to Clean the Fuel System

First, remove all oil from the pump. Next, open the tank, drain the fuel from it, and then fill it back up with fresh gas. Next, remove the filter and clean it out. Once the filter is cleaned out, replace it and close the tank. Finally, fill up your engine with fresh fuel and start your engine up again to make sure that everything is working properly before you take off on a test drive.

The Benefits of a Clean Fuel System

The benefits of a clean fuel system include improved engine performance and less risk for wear and tear. Fuel systems with clogged filters lead to poor performance, so it’s important that you keep your fuel system clean. A poorly performing lubricator will create a lot of drag on the engine, leading to a lot of heat. When the heat builds up, the engine will overheat and fail to perform properly.


Diesel fuel lubricators can be a great way to improve your truck’s fuel efficiency. But with the amount of dirt, dust, and debris that fly around trucks, it’s inevitable that lubricators will get dirty. When this happens, it can cause issues with your engine and fuel system, which can be avoided with some preventative maintenance.
