Cummins filtration filters

[Jeepsinker]

I've been looking at the FH234 series filter setups online and they look very promising. I'm betting they are quite pricey but I can't seem to find a price for any of the units listed anywhere. I would like to put one of these on the deuce if they are as good as the literature suggests and they aren't cost prohibitive. Anybody have firsthand experience experience or knowledge with these? I see they are 3/4"npt input and output so they shouldn't be difficult to plumb in. Also available with 24v lift pumps and fuel heaters!

Single unit on egay for $300 and triple unit for $750.


I don't really see the draw unless you need high volume low pressure. The single one says tested to 30psi. Thats pretty low for a filter system.

 

[Jeepsinker]

High volume low pressure is the key to removing emulsified water from fuel. You do recall I am having an issue with that at present. It may be worth installing in my fueling setup, if not on the truck.

WIX's has a sock like thing you hang in your tank to absorb water.

 

[Jeepsinker]

Yeah I have one of those in there and it hasn't done diddly. They only absorb free water. Though with these lower temps some of the water has been precipitating out of the fuel, it still has a high water content. Visibility through the fuel is only about 3-4". I'm thinking that if I were to install one of these filtration units on both my pumping line and on my truck it would save me the worry of running wet fuel. That way whatever gets past the filter from the tanks and ends up in the truck would get caught by the onboard filter, or what they call a " fuel processing unit".

Have you tried waterblok filters?

 

[Jeepsinker]

Yes. I have a Napa waterblock 10 micron filter with water drain as my primary on the truck, and a goldenrod filter assembly with waterblock filter on the tank output line, as well as one of the big cartridge load tactical filter assembly's inline in my pumping setup. I'm still getting cloudy fuel into the truck tank, but if I let it circulate through the truck fuel filters for a while it clears up in the trucks fuel tank. Problem is that it clogs the primary fuel filter on the truck even draining it daily.

 

[welldigger]

Ok so your getting water into your holding tank? Am I understanding you correctly?

Irregardless of which tank you are getting contamination into, you are either getting tainted fuel or your tank is leaking water in. You shouldn't have to use more filtration than what you already have.

 

[Jeepsinker]

Yes you are correct. It was just a thought as to getting better quality fuel to the injector pump.

 

[welldigger]

Ya I get what you were shooting at. I guess what I was trying to say is if your fuel is that dirty I'd try and find the underlying problem. Especially since you went through all of the trouble to swap fuel tanks on your truck.

For the cost of these filters you could get a small centrifuge. I dunno how effective that would be against the problem you have.

 

[Jeepsinker]

From what I've been researching it is best to have a coalescer and a filter/ separator, and in that order too. Even clean diesel fuel has water content and is hygroscopic, so it can't hurt. The cummins filter processing station seems like it does all that on the truck, but I also want to keep my tank and storage tanks clean. Seems like I must have just got a nasty batch of fuel.

 

[welldigger]

You are correct. Diesel is hydroscopic. That being said the problem you describe is way beyond normal contamination levels. Especially as much as you drive your truck. Mine sits for months and I don't have this problem.

You can never filter too much. At least I don't guess you can. Never heard of diesel being too clean. Well maybe when we refer to ultra low sulfur diesel. But that's another topic.

 

[Jeepsinker]

It isn't a problem with the trucks fuel tank per se, but two of my storage tanks have the issue with emulsified water, and as you can imagine that fuel ends up in my truck. The on board fuel filters seem to be doing a pretty good job of cleaning the fuel so far but at the cost of filter life.

 

[welldigger]

That's what I was getting at. I know your truck has a clean tank. At least I hope it is since you swapped it.

You need to figure out if your storage tanks are leaking or if your fuel source is contaminated. I have had diesel sit for very long periods and not fog up like that. Also fuel bacteria form in the presence of water. I know you look forward to fighting that crap.

I don't know how good the on board filters are at removing water. I think the primary only really seperates precipitated water. I could be wrong.

Emulsified water is very abusive on the hh and injectors. It will score the plunger and hh cylinder and will score injector nozzles. Water is abrasive so to speak in this situation. Since the diesel fuel is what actually lubricates these parts.

 

[Jeepsinker]

I've already treated it with biocide. I know it kills fuel systems to run water through them. The napa filter seems to be working but I'm not sure. I converted it to a spin on 10 micron waterblock a while back. That's the primary. The secondaries are still the factory types.

 

[welldigger]

Ah ok. Now I'm picturing your filter set up.

 

[Jeepsinker]

You need to come down and get your hardtop and I'll show you what I've got going on here.

 

[welldigger]

Ya I was actually thinking of doing that this coming up weekend.

 

[Jeepsinker]

I don't think that would be a problem.

I use WMO/diesel/gasoline blend fuel in my Deuce. I have never had a water problem in the fuel system. The tank is almost always full, or at least 2/3 or higher. It rarely gets below half a tank, and if it does, it is only on a trip. When I get back home, I always fill the tank back up. I have drained my primary filter and never saw water come out of it. My truck runs fine and I drive it weekly during the "non-salty road" season. Sometimes I worry because I have never drained water out of my filters, I wonder if they are working as they should. I guess keeping the tank full (keeps air out which means less chance of condensation) and driving it often helps keep water out. It does not cost any more to keep the truck with a full tank vs. not putting much fuel in it, so why not keep it full and better protect the fuel system? That is how I look at it anyway.
