I just finished slapping together my temporary DC filter rig and hoping to run my first batch tomorrow. Is the stock filter on my fil-right 1604 fine enough to filter the VO and put strait into my DC rig? or do I need to get a finer filter? and where would I get such filters?

the fill rite 1604 puts out enough pressure to run a CF?

No its a transfer pump.

I have my DC rig all put together. I have tried running it 3 time and I have some concerns with the pressure relief valve (the one from Granger). Here is what happened

1st try, pressure build to 90 psi, valve opened, then immediately dropped to 40 psi
,I tightened the valve
2nd try, pressure build to 100 psi, valve opened, then immediately dropped to 60 psi
tighten valve again
3ed try, psi went to 115 and the valve did NOT open, I got nervous and unplugged it.

Should I invest in another valve or is this normal behavior for a pressure relief valve?
My concern is for the safety of anyone standing around and of the hundreds of dollars of equipment that this $5 valve may damage.

One other thing I should note, there is a pressure relief valve built into my pump, which I did have to turn up. Should I just set it to 90 psi and use it instead of an external one or is there an advantage to having an external valve.

Sounds like you may have the wrong spring in it, try a different one. Set it at 100 psi and use it just as protection. Set the one on the pump to 90psi.

I see, I misunderstood the job of the external valve.

If I run a batch of milky looking VO through the CF will it clear up in a few hours or is it a bad idea to run VO that is in that state?

Sometimes it will clear it if you get to 160F. It depends on how abused and how many emulsifiers are in it. If it doesn't work, settle for a day, drain off the bottom, and try again.

Starting it Up!

Postby newtoveggie » Sat May 10, 2008 8:51 am

Six months after I constructed the CF Sunwizard designed I have put my first Eight (8) Gallons in the 55 gallon drum. Eight Gallons for several reasons. I want to make sure there are no leaks on the seams before I get going. Secondly, the bottom quarter of the cubie is cloudy so I stopped pouring at that point. Do you guys dump in everything or pick off the top? What is the cloudiness. Lastly, I think I will run the first eight (8) Gallons through the piping to clean it out. I used Real Tuff teflon paste and I am sure some of it is on the inside of the pipes along with whatever else comes inside cast iron pipes. Should I be concerned about teflon paste at all? Should I even run it through the CF or just run it through the piping then dump? Is there any concern about a rusty barrel?
Sorry for rambling but I am so excited to begin this journey that I have only read about from you guys.
If I seem frantic it is because my mother's day gift, on Sunday, to my wife is giving her and my son a ride in the truck powered by Veggie Oil. It is the least I can do since I have been a recluse in the garage for Six months.

Pick off the top, and save the rest and run it as a PHO batch after you accumulate 45 gallons of it.
What is the cloudiness.

See: You have white crap in the bottom of cubies and barrel?

I would run it and the CF will remove rust particles.

Teflon Batch?

Postby newtoveggie » Sat May 10, 2008 9:54 am

I don't know what it would do, so if you have a large excess of it inside the pipes then it may contaminate many batches of VO. Normally any excess goes only outside the threads as you screw in the fittings. You could try a sample of it in a jar and see if VO dissolves or disperses it.

I am about to put a 3 way valve in front of my CF to transfer fuel from the barrel to my tank. I don't have much experience with pressurized systems and I am wondering if this is a good/safe idea?
