There is room, but not much. And it'd be hell trying to get to the stock filter. What are you using to mount it and what are you mounting it to?

 

Standby for pictures. I just got it done. I'll post them when they are approved.

 

Here it is.

It can be mounted on top of the grid heater too. I wanted mine lower. You still have full access to the main filter. This filter doesn't go behind the air horn at all. If you go on top of the grid heater, it can be moved tighter to the engine.

I've got a ton of pics about how to make it. Let me know if you are interested.

 

Sure, I'm interested in some more pictures. How thick is that plate?

What kind of tool did you use to cut the metal fuel lines to the CP3? Is that 3/8 hose as well?

 

Plate is 1/8" thick aluminum. You could make it thicker if you wanted. That filter takes a bit of torque with a filter wrench to get tight.

I didn't touch the fuel lines. That is the way they are from the factory.

The stock fuel lines are 5/16" tubing.

That fuel line is instagrip (Goodyear). I don't know if it is labelled wrong or what, but it doesn't fit the tubing or the hose barbs well. I'll replace it next time I change the filter.

Is there room to put it on a Dodge there ? It can be put on top of the grip heater if needed.

 

What is the overall length of the filter and mount?

Do you happen to have the dimensions or a pattern of that mounting plate?

 

Superduty. Can you post a diagram on how you plumbed it. Thanks. I will be nominating you for a Nobel Prize in "Simplicity" Engineering.

 

"What is the overall length of the filter and mount?"

Bottom of the plate to the bottom of the filter is 8.5". This filter is the 1R-750. There is a 1R-749 that is longer if you need more life/capacity.

"Do you happen to have the dimensions or a pattern of that mounting plate?"

My plate is 9 1/8" long. You should make yours 9 1/4" long. This is for mounting underneath the grid heater like I did. You need it that long so the filter clears the hoses beside the engine.

If you mount on top of the grid heater and use the short filter (1R-750) you might be able to move it closer to the engine.

It is quite easy to change the way it is now and one still has good access to the stock filter.

Pattern ? I didn't CAD it up. I made it by hand. I didn't want to program the CNC. My pictures tell the story of how to make it. It took 2ish hours from start to drive.

Measure it up. If it fits a Dodge and people want it, I will write up an article in my spare time.

 

"Can you post a diagram on how you plumbed it."

You should be able to tell from the bottom picture. The tubing on the right at the bottom comes from the bottom of the stock fuel filter assembly. It goes to the left side of the 2 micron filter, in the IN port. I crossed the lines like that so there wouldn't be any tight turns in the hoses. Otherwise known as kinks.

The line connecting to the OUT port on the right side of the filter goes to the tubing that goes to the IN on the CP3.

Nothing magical. Lots of room to do it, really. I've looked at the engine several times for a place to hang a filter and this seemed like the ideal place. I didn't want to get involved with the manifold, but the location was perfect, so I did.

I think I am happy with it.

 

Did you need a second gasket for the mounting surface on the manifold. It's hard to tell if you've got one under there...

 

Yep, second gasket is required.

Hey Superdudty. Do you think I could get rid of my stock filter&housing using this setup with a 5micron filter only? Would that be enough filtration? What is the filter efficiancy of the stock filter? I'm just wondering, cause with this setup, you wouldn't have to worry about overpressure as much, and would be real easy to place a gauge on a t-connector on either side to monitor pressures.

 

You could use a filter like the Cat to replace the stock filter. At one time Cummins had a 2 micron replacement filter for the B series. I don't know if it is still available.

The stock filter has a fuel heater, which I think it a great thing to have if you live in a cold climate.

I'd get one with a water trap.

Stock filter is 10 micron.

I'm not too worried about over pressuring. It isn't going to hurt the Walbro and I'll just watch the filter pressure to see when things need attention.

I like having dual filters staged in sizing like this. 10 micron first, then 2 micron. I don't like 2 micron by itself because it will plug more and more easily. This way the 10 micron cleans out most of the debris and the 2 micron catches the smaller stuff.

I like having 2 filters when changing. If I mess up changing the stock filter and somehow debris gets past it, it will get captured in the 2 micron filter.

 

In case someone is implementing this system, I don't know if I am happy with the Donaldson filter head. The head just barely covers the filter O Ring and the center O rubber ring seems a bit big for the filter. It takes a bit of torque to get it to stop leaking.

I was thinking the head was designed to only marginally cover the filter O Ring so that no dirt could accumulate and get the next filter dirty when changing filters. But now I am not sure, and not sure if I like it.

Stay tuned.

 

I just bought the Fleetguard #3930618-s filter head and a FG FF5320 2micron filter. They fit perfectly together (obviously). The filter head looks exactly like the Donaldson that SD has. BTW SD, maybe try the Donaldon filter P551313. It will probably fit better than the Cat filter on that mount. It's 2 micron as well.
