Cat Water-Separating Fuel Filters - Got Two for $8.99 on eBay

[sdowney717]

Wanted these to perhaps setup a portable tank polishing system and got them for good price.

So looking at these, they have a thick GLASS not plastic bowl, the sealing rings are metal for the plugs and the thread is 1/4 pipe for fittings. They also have a metal fill port - vent on the top.
The small drain port is plastic. I was also wondering if these could go in an engine room for a gasoline boat if you changed the plastic drain, tapped it for a 1/8 pipe thread and put a metal drain cock.

Any feelings about that? I had read plastic fuel bowls were not ok for gasoline engine rooms, but what about glass?

[sdowney717]

Oh, I found out the threaded pipe connection is not 1/4.
The thread is a very close metric thread?
Can you get metric hose barbs?

Otherwise, I will have to retap for 1/4 threads. The 1/4 pipe nipple is slightly bigger than these threads.

The internal threads are not tapered and the existing plugs use a sealing ring, so this might be it.

Parker has adapters that fit, check their online catalog

Try the local hydraulic shop.

I would be carefully with todays gasoline in filters made for yesterdays diesel fuel. The o-rings and seals are going to be subjected to ethanol fuel and failure is just around the corner.

We are replacing gaskets, seals and o-rings weekly in our systems. While we have systems for diesel and systems for gasoline, we still see failure.

[sdowney717]

I decided these will be portable temporary use as in tank polishing.

I am not surprised that seals fail. Fuels today are the worst we have ever had, in so many ways. Price is bad, what they are made of is bad.

I added a WIX 10 micron right before pump, wix 24348 water separator into my filtering system. This filter is made for either diesel or gas, spins on, is large and has not leaked failed etc...
The Wix 24348 is made for fuel dispensing pumps.

One head of many to use can be a 24001

On my ccs1136 cartridge filters, the cork gaskets OEM cement fails. I have been regluing them on with SealAll.

FF2D luberfiner is also a comparable spin on to Wix 24348 and has a metal drain valve, buy at Autozone. You can replace the plastic drain valve on the wix with a metal one as it uses a 1/8 pipe thread.

here is a pic of that WIX

[sdowney717]

Went to the hydraulic hose store. And got some fittings.

He says they are SAE 5, I thought SAE 4.

So picked up four SAE 5 ORB to FJIC 3/8 flare


he was out of the adapters to go from sae 5 ORB to female NPT 1/4 pipe. Which I need 2.

FYI, I sent the gasoline threw the CAT filters back and forth 80 gallons worth multiple times and the filters worked swell. One tank to the other about 5 times. The o rings did not swell up, leak, etc... And the glass bowl caught some varnishes.

[sdowney717]

Found out this is also used for gasoline engines. From the WIX application list for the 33166 filter. Mostly diesel but there are some for gas.
Part Applications

Typically rubber parts in gas do swell. If you let them dry out for hours, they may shrink down again.
