I got the 4770 filter base yesterday with the NAPA 33528 2 micron filter.

I want to mount this pre pump on my frame rail.

I was wondering if anyone had some good pics of how they mounted it.

Can I drill 3 holes in the frame and mount it?

I have seen it welded to the frame. I just don't want to cause damage to the frame.

Thanks alot for the help guys.

 

Take a look at figure #12 from ITP instructions. It's were i mounted mine, making changing the filter easy.

I don't have a picture of mine, but I went and had a bracket bent to mount it to the frame rail, but my filter base is different than the one you have. I'll see if I can get you a picture when I get home.

 

I have this filter head

Not the ITP one.. It side mounts.

I am gonna get a piece of steel and bend it in an upside down U shape and bolt it up and lock tite it

 

Andrew, I may not be remembering things correctly, but IIRC, a 2 micron filter element on the suction side of the pump may have too high of a pressure drop to work in the pump suction without causing the motor to burn up.

I know that lots of Cummins systems use this same element just north of the tank, but I don't know if the fuel pump on the Didge Cummins is inside the tank ahead of this element.

The most typical approach on our PSD's is a 10-20 micron filter element ahead of the pump (if any), followed by the 2 micron rated element that can be located either down on the rail at the pump when eliminating the fuel bowl or relying on the stock fuel filter in the valley that is also rated at about 2 micron.

I'm not saying this 2 micron filter won't work... but I would be very cautious about putting something that tight on the suction side of my pump. he only thing that would make me more comfortable with this concept would be having some flow ratings data showing that the 2 micron setup will flow enough fuel at very low pressures so as to not starve the pump, and it would need to be really large to have enough surface area for that, too.

 

Pete, Thanks alot for the thinking. That didn't even cross my mind.

I'm glad you posted. I was gonna send you a PM this week cuz I washed my cover again and I love it!!

Here are the specs on this 2 micron filter.

I am already running an inline filter pre-pump. Would I be better off mounting this post pump for now and adding a bf1212 filter pre-pump in the future?

 

Andrew:

I looked over the BF1212 specs, and listed the info below for reference.
Fuel Filter Specs (BF1212):
Flow Capability: 210gph @ 1psid / >300gph @ 3psid (the "d" in "psid" is for DIFFERENTIAL pressure across the element)
Filtration: 86% Efficient @ 4 micron / 99% Efficient @ 20 micron
Water Removal: 93% @ 60gph / 87% @ 120gph (based on 2500ppm free water injection)
(emulsified water removal will be approximately 3-5% less)
Burst Pressure: 150psi
Collapse Pressure: 100psid

Cross-referenced alternative elements for the BF1212 that fits the Baldwin fuel filter head.
- Baldwin BF1212
- Donaldson P55-8020
- Fleetguard FS1212
- Fram PS3712
- Luberfiner LFF8020
- WIX 3340

Now to your questions and in reference to the specs you posted on the Napa element.

The Napa element's flow rating appears to be plentiful, but again, there is no differential pressure identified for that corresponding flow rate. In other words, if those flow rates are for the kinds of differential pressures that you find on the pump's discharge, then the flow rate you will get at the lower suction side differentials (1-3 psid range) will be much, much less than the listed rate of 12-15 gpm.

Again, not knowing what differential pressures were used for the 12-15 gpm Napa flow rates, it just leaves the question begging and I can't make a knkowledgeable call on it. The only reason I even questioned it is beacuse I have not seen a suction side element rated so low before... not that they could certainly be out there.

That said, I would try to find out those pressure ratings for the Napa unit before deciding which location it would work best in. If it is more suited ofr pump discharge pressures, then by isntalling it on the frame rail near the pump, you gain the flexibility of being able to do your own fuel bowl delete and eliminate the existing OEM fuel filter in the valley.

Looks like you've already done some good investigation thus far, but just need a few more specs to know the best path forward.

Question for you...

If you're already running an inline filter ahead of the pump, why change? I've been running the ITP kit with the BF1212 for over two years now and have had zero problems with it. Personally, as I look forward to bringing my mods over to my 7.3L Excursion bit-by-bit, I plan to go with a clear bowl Racor unit next time on the pump suction so I can take a quick glance for the presence of water without necessarily having to drain the filter element. Aside from that goal, I would use the BF1212 again for that same application. However, if what you have is working well, why change? There are a number of guys running the small inline filters with no trouble, and they are a little cheaper than the Baldwin's.

BTW... it's always good to hear about continued satisfaction with the covers. Thanks for that.

 

YEP! What he said! Brian from BTS said I should go back to a 30 micron (which I did) from the 10 micron I had pre-pump because of the possibility of over working the fuel pump.

 

Andrew,I have the same filter set up that I am going to mount post pump when I do my Reg Return.

I found a spot under the drivers floor board and behind the flinder well to put it.

I'll show you on fri when you stop by.

 

Looking for a simple screw-on filter system between the tank and filter on the engine. 2002 7.3. Thanks

 

I mounted an add on filter under the hood between the rail pump and the OEM. If i can figure out how i will post pics.
I got the head and get filters from Tractor Supply Company.

Here is mine

Filter is a Wix 33405 10 Micron filter.

I am very happy with it.

I plan on a 2 micron post pump filter this summer

 

What's wrong with the ITP kit? Everything you need, no trips to the hardware store, mounts like it was meant to be there.

 

I just want to put a filter mounted on the frame. I know the ITP kit is great after reading. I just don't want to drop the tank and modify anything. So to make it simple can I just cut the line between the tank and OEM filter and install a filter? Thanks.

 

Well, talk to Dennis. He might just sell you those parts. If you don't want to drop the tank, why do you want a fuel filter in line for? Those filters are so that we can remove the filters in the tank. Not only does it eliminate the fuel disconnects and stops the mixing valve, it is nice because it eliminates the filters that are already in the tank. In my case, the fuel gets sucked, debris and all, into the pump. The only thing standing between that is the rail mounted filter.

Something else. Filters cause restriction. Adding another filter ON TOP OF the tank filter might cause more restriction than you desire.
