The one from Summit looks tiny compared to the Cat and Fleetguard. I wouldn't think it has enough volume for our application. It's also a water/fuel separator, so I'm assuming the 2mic filtration part is even smaller than the canister size.

 

Ataboy's location is deffinetly best if you live in a colder climate, it seems like being tucked up farther in the engine bay would help keep the filter a little warmer. My fuel gelled in the Cat filter this past winter whilst in Fort Wayne durning that two week cold snap. Easily cured with a torch, but still a minor pain. My guess it happened because of the lack of shielding, and no heat in that area. This was with PS, I was surprised...

 

You've got a really good point there. A blowout or kicking up a piece of something could seriously ruin your day.

It looks like he doesn't have the wheel well liner installed there in that pic. Maybe with that on it's a little more protected from the tire?

 

Im sure it flows enough, those filters are designed for 15liter engines not 5.9

 

You could always just buy the head housing and run what ever filter you want.....http://store.summitracing.com/partde...?part=PRM-1791

 

Where do you see that it's designed for 15L engines? AFAIK Perma-cool is known for making aftermarket electric fans and coolers, not really industrial stuff. The rating shows it definitely does flow enough, but how much diesel fuel will it really filter before becoming clogged?

When it comes to filters, size is going to make a difference. There's going to be a physical limitation on how much material can pass through a filter before it becomes restrictive/clogged. If you look at all the other filters, they are all larger than that one. The FASS systems also use a separate filter and water separator. I'm sure there's a reason the others are like this.

 

I said those CAT filters are disigned for 15L engines, they might be a lil over kill for a 5.9

 

perfect!! thanks

 

I've never had my CAT clog, I usually just change it out every 35 - 40k miles. Idling the pressure is the same at the OEM filter head (Genos cap) and the CP3 inlet, I moniter both at the same time in cab. While driving there is usually no more than a 1psi max differential btween the two.

 

Ah, you didn't mention the Cat part and then referrenced my quote which was saying the Perma-Cool looks to small.

I don't think anyone can argue that the Cat or Fleetguard don't flow enough.

 

will putting in an additional 2 mic filter (like the cat one) be ok if i'm running the factory lift pump? or will there be too much restriction for it?

 

I think you would be fine with stock fueling. If you're using a chip/programmer then it might become a problem.

 

I would not do it unless you are monitoring fuel pressure. With my stock setup the fuel pressure was only 6-8 lbs. You do not want to be starving the CP3 of fuel. If you watch pressure and it looks OK then go for it. I would be prepared to add a aftermarket fuel pump if the pressure drops to much. You do not want to harm the expensive CP3. The fuel pump will look real cheap compared to replacing the CP3 if it fails.

If you look close at my pic I drilled and tapped a boss in the filter head for 1/8" pipe fitting to mount a guage until I get a guage setup for the inside of the cab. This tapped hole is on the outlet side of the filter element and I have 8psi at idle with a stock lift pump. I don't think the filter restricts very much if at all. Mind you it has a 1" filter thread and you have 5/16" fuel line there, you think about it.

 

It won't be the clean filter that will hurt the pressure. It wil be a week or 2 after running when the filter starts to collect some crud and make the pump work a little harder. All I am saying is it will be important to watch the pressure so you will know when the filter is getting dirty. I have the GDP-392 pump in front of mine and when the filter gets dirty I can tell by the pressure drop. You do not want to run the CP3 without fuel or it will get expensive.
