Fuel filter location.

I believe it is only one the cat have 2 make sure you have starting fuel it can be a night mear to restart it ,if you have a water separate then for sure you will have 2 good luck driver

 

you should have a secondary one after the pump. it is where detroit typically puts the fuel temp sender as well.

 

Normally one hid up under the compressor and another back under the starter. Sometimes one is on the frame. LFP815, 33118 and LFP816, 33120 I thank. Some have a ball valve on one of the filter housings. Cut that off first and last. Stops all the fuel from going back to the tank. Some companies special ordered different stuff but two is normal. Good Luck with your new truck.

 

My 07 freightliner with a Detroit has only one filter and it's a Davco off the frame on the drivers slde.

 

Oh and yes just fill them up with fuel. When I start them I run at 1500 RPM for a bit and not at the time of oil filter change. I used to just pore it in the center until JD started supplying an adapter with some of their filters. It is kind of like a funnel that screws into the center and all of the fuel has to go into outer holes, normal direction of flow. I decided there must be something to that or they would not supply them with the filters. Now I put my thumb in the center and fill them that way. Do it anyway you want. A 6 pack of injectors is only about $2,300.

 

Same as my 06 shaker...

 

Good deal

 

I often used howes instead of diesel in the filters that way there's no chance of water getting to a injector.. nowadays it's pump like crazy on the paccar engine
