How to Polish Car Parts
Priming a diesel engine can be difficult and dangerous. You definitely need to have some prior diesel engine knowledge or have someone helping you that does. This project is plenty capable of being done if you pay attention to some key steps.
- Inspect all fuel lines for any leaks. This will involve crawling under you vehicle and probably using a flashlight. It's very important to know if you have any leaks. You'll need to repair these leaks first before doing anything else. You might need to add fuel to your vehicle to see if any leaks appear.
- Remove your fuel filters and clean them. Dirt and debris can build up in your fuel filters and cause fuel to not flow properly. The location of your fuel filter will vary for each vehicle. You need to find a mechanics manual; your owner’s manual probably won't have the fuel filter location listed.
- Pump your injector pump until you notice fuel pressure building up. It's very possible air is in your lines and it might take a long time to build up pressure with all the air.
- Find the bleeder screw near your injector pump and crack it open just a little. If nothing but air is coming out, you need to pump your injector pump some more. Repeat this process until you notice fuel coming out from the bleeder screw. This process is similar to bleeding break lines if you've ever done that before.
- Try starting your engine to see if you've primed it enough. Don't be alarmed if it sounds a little rough at first. There still could be a little air that's flowing through.
