Fuel Filter

[Odie]

I just got back in town and found out that my truck hasn't been starting. I primed the fuel filter and diesel started leaking out. I went and got a new filter thinking that the gasket had gone bad or something. I put the new filter on and it is still leaking. I think the leek is on the pedestal that the filter spins on to. Has any one had any problems with this?

Where is it leaking from the hand pump or the bleed screw.

I have several filter mounts here if you need one.

Stupid Question
They is an o ring on the top of the filter?

 

[NelsonDiesel]

Filter housings do go bad and leak. Where do u see the leak from?


Yes there is a large o ring on top of the fuel filter

If you need a whole new housing let me know I can get em fairly cheap straight from the dealer.

Sometimes it will even be TWO o-rings on the top of the filter. Sometimes the old o-ring will stick to the top, you won't see it, and now two will be there and it will leak.

Don't ask.

Many of us have done that. Once.

Time for a filter by the tank and do away with that restrictive factory one.

Always wondered if anyone had ever just run the FASS-type filter setup along the frame rail and bypassed the OEM filter altogether.

Have on several. Trucks run alot better, fuel temp is cooler going to the CP3. Ever felt you factory filter after truck has been ran hard? Fass filter still get warm from fuel temp in the tank but not as hot. A buddy did alot of testing an has the info I will see if I can get it from him.

That would definitely make for another interesting thread....and make me do this :banghead: for buying just the pump (sans filters)

How does that work in a colder environment? Doesn't the factory mount have an element in there?

Curious, because it is -11*F right now.

No heating element in the filter heads far as I know. There is one back at the tank.

The heating element is next to the priming pump on the filter housing what you see in the back is the fuel cooler.

The bleed screw is tight and lo leeks there. I did check for the o ring on top and made sure the old ring wasn't stuck up there. Done that my self once before. What it seems like is that I'm not getting the filter on tight enough. I know its tight though. The bottom of the filter is good to. Checked it and made suer there were no leaks down there. I have been looking into the air dog 150 lift pump. Sounds like I just need to get that and by pass the factory one.

Did that on the oil filter once! About a gallon and a half later I noticed the pool in the driveway. That was a mess to clean up in the rain.

Something that i just thought about. If I was to bypass the factory filter with a lift pump. How would I defeat the sensor at the bottom of the factory filter? Or is that something that could just be left unplugged?

 

[Noreaster]

unplug it

I mounted a filter head under the truck after my lift pump. I use a Wix version of the 5 micron Cat filter. I removed the stock filter head. It was easy to bypass. Just take the banjo fitting out of the outlet line. Remove the filterhead. Put banjo fitting in the line that ran to the filter head inlet. Bolt back on the FICM.

Also helps to run 1/2" line/hose all the way up from the liftpump. Could also run a fuel cooler along the way.

I stand corrected, thanks Henry.

Thanks for all the help guys Now all I need to do is choose a lift pump I was looking at the air dog 100 or 150. Any thoughts?
