My CUCV spin on fuel filter mod

[69dieselfreak]

any big truck junk yard should have them just tell them caterpillar fuel filter head with the primer and you should be good

Here is what mine looks like It also has a wix filter

Looking good.

The cat 3208 had the filter bracket and primer pump too it might fit better as its a smaller version of the one pictured.

After my stock filter base went bad I put a RACOR490 on mine. It has a 24 volt heating element,clear sight gauge with a drain at the bottom for watter, and best of all it has a priming botton at the top of the base along with an air bleed hole. I am useing it by it's self with a 10 micron filter. The only draw back is that RACORs are kind of expensive.

I like that Ram Air you've got on there. I found a civy 6.2 in the local junk yard and swipped the factory cold air off it. Works good.

Hello Jimmy,

Where does that ram air hose from the air cleaner lead out too?
a snorkel? or elsewhere? Do you have a photo of that too?

Thanks

Pawnshop, one thing I noted was the use of the Napa 4309 base, which is a 1-12 thread. If you had used the 4770 base with it's 1-14 thread, the number of spin-on fuel filters available to use in terms of size, nominal micron, physical size and water drain would have about tripled (i.e. from about 10 or so to +35; which, may or may not have helped in installing your fuel filter installation.

I found this out when I designed my pre-pump fuel filter system for my F-350 PSD.

For those of you contemplating doing this to your vehicle, here is a list of Napa spin on fuel filters with micron size, filter size, water drain yes/no and the applicable filter base.

Hope this helps.

Thanks,

Al

Nice conversion.

Definitely a nice conversion. I have never had a problem with the box style filter, but the spin on filters are much more readily available everywhere you might have a problem. In my location in central PA, a heater of some sort will be needed though. If not, I'll be sitting along side the road on my way to work.

Thanks all for the information. I have been running around town all day trying to find a generic filter head for doing this same project. I was planning on using 2 of them a primary and secondary. That might be a bit of overkill. Napa wanted $50 for the one the guy showed me. Years ago, we used to have high performance auto parts stores here in Las Vegas. I remember buying these heads for $20. I guess I am just getting old.

4770 1"-14 threaded filter bases for $21 but they're on back order: Wix 24770 & Napa 4770 Base - ON Backorder!!!: FleetFilter Secure Online Store

The 1"-12 filter base for about $26: Wix 24309 & Napa 4309 Base: FleetFilter Secure Online Store

If you get desperate, Amazon has the 224770 base for $29. Amazon.com: Wix 24770 Filter Mounting Base, Pack of 1: Automotive

Good luck.

Hey CycleJay the ram-air pipe goes to a 4" hole in the radiator core support. For some reason they tac weld a piece of metal over it on the cucvs. Anyhow if you type " my cucv ram-air project " into the search function on this site it will take you to my mini write up about it and the pics. Includeing the one of the front where the air comes in at.

i would like to do this to min. ok to do in a cold climate? thanks

Excellent thread!

My civilian pickup with the 6.5 has an electric pump that makes changing filters a breeze, that inspired me to install electric pumps on all my CUCV's I have owned.

Flip the switch, push the air out, flip it off. As a plus if your mechanical pump ever fails, the electric is right there and will work just fine. Any time I have had a mechanical pump fail I just removed it and ran just the electric.

Mine came with a 5 - 6 psi electric pump installed. Turn the key on and the pump starts immediately.

Similar bleeding directions. Turn the key on. Open the filter valve. Wait for fuel to spurt out. Close the filter valve.

cost was LESS than $100 at Napa...

mine has the stock box filter - new backing plate/bracket/filter

WALLEW,

[wallew]

As you can see, attached to the frame rail, inline on the passenger side. NO big deal. If memory serves, there is actually a short piece of rubber fuel line in this spot, so putting it here actually makes sense.

 

[WARWAG]

Sorry there Old Timer. I thought you were a young whipper snapper like myself............ OK so Im not so young any more. Thank you though for the picture.

If I convert to the spin on water/fuel seperator filter do I have to run a second filer also. Does this one fillter seperate the water and whatever other trash might be floating in the tank?

 

[pacebm]

As long as the filter will handle 30 gph it should be good to go. I can't imagine needing more capacity than 30 gph with a 6.2. Filter will take out your water and filter the diesel. Do you have a specific filter in mind?
