Do you think this will work? - Diesel Forum

I have at least 20 new Fram P8HA oil filters, they fit my Gasser Ford and 22RC Toyota. i no longer own Toyota and gasser Ford has not been run a year. What I have in mind is real simple if it works. The outlet on the Fram filter is the hole in the middle looks to be pipe thread 1/2 inch. Fram filters to 28 micron as bearing clearence in a Ford is 40 micron. the idea is to flow processed once filtered biodiesel from the processor while still warm before it goes into the wash tank. What I am going to try is to make a tree with 3 or so filters plumed into a manifold by the outlet of the filter. Oil will be pumped through the filter basicly backwards....into the outlet and flow out the inlet holes, the many small holes around the parimiter of the filter.So any thoughts.

At some point you still need to have a 10 micron rated filter in the system. Unless you already have the filter heads to fit all these Fram filters, I have a feeling you'll be spending more money to get less filtration.

Sell the Fram filters on eBay and take the money to buy what you really need. I think you'll end up with better filtration and lower ongoing operating expenses.

Consider the cost of the filter heads AND the replacement elements. In future systems I'm leaning toward Cim-tek and Luberfiner. I have a Racor filter but just can't justify the extra expense.

ToddT, Selling the filters on E-Bay is way more trouble than it worth to me.
The oil is prefiltered before it is put in the processor I have no idea of the filtering size of our prefilter but the oil comes out pretty clean We do get quite a lot of junk in the filter sock but the socks we make are cheap and washable.Plus I am building a press to squeeze out the oil from the the gunk from and modified cider press. The solids I will feed to the bears...don't ask.

We filter by gravity the first filtering through a leg off of denium pants. We let the oil flow through very slowly usually takes about 5 days for 50 gallons. This oil is ready for the processor when we have enough. We have yet to process any oil.

We do have around 120 gallons of filtered waste oil and another 200 of unfiltered. Low temps seem to make the gunk settle out so we are bideing our time and presently just filtering. simple process, decant cold oil to clean container placed on stand over another barrel open tap and let oil flow into bag filter arangement. Store oil until ready to process we have 800 gallons of clean storage.

So the plan is when oil is at temp being transfered to wash tank from the processor it will go through the Fram filters, this whole filter system for the canister filters has so far cost zip, nada, nothing. Filters were free to begin with and we have pipe and fittings to make manifold also free. Once oil is run through Fram filters we plan to finish it through a good 5-10 micron or so, filter before introducing it into out trucks.

I also have a Raycor on my truck so I think we have enough filter. The fram is an expirement to see what happens. Filterheads I am assuming you are thinking of a spin on filter remote holder....not so just a pipe threaded in the middle allow oil to flow in and run out the small holes and flow into the barrel, extreamly simple. The question is will the oil flow through the filter in oppsite direction the filters were designed for?

The only reason I am using Fram filters is because that is what I happen to have. what type of filters are Cim-Tec and Luberfiner? We have a truck a boat and a tractor Raycors are a bit spendy.

ph8a filter has 3/4 16 threads and 1/2npt will not thread into it. The diameter is right but the tpi is wrong. Pipe has a courser thread.

I'm all for doing bulk filtration with blue jeans, cheesecloth or whatever. But, at some point in your prefiltering AND in your vehicle, put a filter with a known micron rating of 10 microns or less. Using these Fram filters will reduce the load on the finer filter elements. But, you need to have a known-micron rating filter as a last step protection for the injectors.

Blue, thanks for the reply, all we need do is a minor set up on the lathe and it's new threads. It's nice to have toys, even if they arn't yours.

ToddT i believe I said we will be filtering to 5-10 micron, just need to see which filter I have in the shed, have a lot of marine stuff, filters for fuel, and water. most of the stuff is Raycor but i need to see what it is before I attempt to use it. this is all an expirement don't need to get in way over my head. But if I can play with my Ideas thats what I'm about. Cost enters in only when I have to buy something. So filtering thus far has been free. We have about $50.00 so far in the Appleseed processor and the same in tanks. A whole lot of stuff we just had on hand. In fact if you want to get real funny about my stuff I am using a fire pump to collect oil with a modified sea strainer on the end of a pick up to help keep the junk out. Some time soon we will have to get serious and attempt making some fuel.

Another thing to consider is that the oil filter will have a bypass and allow unfiltered oil to get thru once the filter has clogged. I agree that there are cheaper/easier ways to get it done.

dssamp · 12-20-2005, 06:41 PM

Lets see here. He already has the pipe. He already has the filters. Won't get much cheaper than that. [img]/ubbthreads/images/graemlins/confused.gif[/img] I don't think ya'll get his point....
Seems he just wanted an opinion on the process. Why won't it work? He is going to push oil down the 3/4" opening, thru the filter and the "strained" oil will come out the holes surrounding the center opening. Seems workable to me. I agree after a while the filter will become clogged...but not a big deal. Unscrew the filter, put on another one. Cheaper than 32.00 for a whole house filter like I'm using.

dssamp Thats the idea. I did have in mind the full bypass design of the filter will it be affected by flowing oil through the filter backwards.....I will soon find out. This is one of those cost is not a consideration projects,no animals will be harmed. Could be the filter will stop flowing when plugged. I dont know but there will be some materials filtered out of that I am quite certain. Best of all if it does work it was free.....

I dont think the bypass valve will come into play at all, with the flow going in the opposite direction I think the pressure might work to keep the valve shut.

I wonder how the element itself will stand up to the reverse flow? Instead of flowing from the outside in the center and compressing the element now it will be trying to push it apart. I think a lot of it is gonna depend on how well the end caps are glued on the filtration media.

I wonder if it would be better to submerse the filter in the dirty oil and pull the oil into the filters in the normal direction?

Bullwnkl · 12-20-2005, 11:23 PM

Submersing the filters is a very interesting thought, same plumbing just put filter tree on inlet of system it might take an extra barrel and step but thats simple enough with our set up. in fact this makes lots of sence, thats why i asked the question in the first place....not to be told it's too expensive...how expensive is free any way?
