Fungus abounds!

At least, that's what I assume it is. The car sat for two years before I bought it, and the fuel that I drained was downright nasty. This is my fourth filter in 7000 miles, but it only has 100 miles on it! After I started adding acetone, naptha, and kerosene to my WVO/RUG mix about 1000 miles ago I noticed the prefilter collecting more junk. When the car hesitated up a hill, I changed both filters. Less than a week later, it lost power again. I backflushed the filter with kero to get this junk.

I am wondering whether its the solvents or the cold that has precipitated this. Unfortunately for the application of the scientific method, it was the onset of cold (freezing) weather which encouraged me to add the solvents. Anyone have any sort of similar experience linked to the cold or solvents?

Im working 70+ a week thru Christmas, so I dont have it in me to do the proper things like clean the tank strainer, etc. Im just carrying 3 prefilters. Let me add my voice to those who say: ALWAYS carry extra filters and the tools to change them.

Scot



BTW, has anyone tried a 1-13/16 socket on the tank strainer?

Try running some starbrite startron tank cleaner through it. A few good reports now, other than my own.
You should also add a biocide and some water dispersant.

I 2nd that emotion.. I used Starbrite from Pmari's suggestion and haven't had anymore filter issues. But I used the Startron diesel additive....link
http://www.starbrite.com/prodcatalog.cfm?ProductCat=Automotive&ProductSCat=Gas%20%26%20Diesel%20Additives%20%28Auto%29

Get it at West Marine or online....It works differently than others by using enzymes vs peticides...

Thanks. I do plan to treat it, pull the strainer, and blow out the lines when time permits. Also, I was wondering if fungus can clog the vent line as there is a hissing when I remove the fuel cap after driving. Is that normal?

check for something clogging it up under the drivers side rear floor...if the rubber vent nipple is gone mudwasps may have built a nest there....

Update

I finally got around to pulling the tank strainer. I fully expected it to be clogged because the car sat for two years before I bought it. It was completely clean (see post #9-thanks, Jay!). The fuel I drained was very murky but had very little particulate matter when I strained it. When I went back to examine the particles from the little filter, I found that they will MELT upon application of heat. Now I'm guessing that I'm prey to wax precipitating when diesel and WVO mix. I had been adding 100ml of naptha per 5 gal of WVO/RUG blend to prevent this, but no dice. I'm going to try mixing dino and my blend in the old garage lab to see if I can duplicate this.

BTW, for those who have access to large standard tools, a 1 13/16" substitutes nicely for the 46mm needed to remove the tank strainer. Not that I would EVER recomend anything but the correct tool properly applied.

Thanks for the use of the facilities, Jay!

Scot

I think the startron is the best microbal killer and it will disolve via enzyme the little buggers.

Wax-eating enzymes?

Bring 'em on; I can feed 'em!
I haven't seen Startron locally yet, but I'll keep my eyes open. Not an issue right now as the fuel is 'right purty' since I drained the tank-course its all dino from a high volume station. But, I need to get back to WVO before the health department catches on to how much I've got in my basement!

Doning mad scientist disguise for further experimentation...
