The CASE 400 diesel tractor has been sitting several years and several more before that. The bottom of the diesel fuel tank has a deep layer of sticky, rubbery, black goo. It is at the level of the top of the standpipe coming up from the valve.
Th fuel shutoff valve was clogged. I took it off and cleaned it. It flows very well now.
I want to clean the rest of this stuff off of the bottom of the fuel tank. Is there a solvent I can use to make this easy ? Brake cleaning spray did help soften it from the standpipe and fuel valve/petcock.
I've read steam or a high pressure spray can do it. The filler opening is only about 3". Not sure I can get all around in there.
I also read about some solvents that are said to help. I bought a gallon of each to try. Lacquer thinner, Zylene and denatured Alcohol(fuel). Also got a smaller container of Bio-Kleen for afterwards when I refill the tank with some fresh diesel.
My plan is to drain the tank and remove it. Remove the fill strainer, water trap and petcock. Then go to work on the 1-1/2" to 2" deep layer of black goo.
I realize I also may have some time to put in on the metal lines. So far I know the one from the shutoff valve to the 1st fuel filter is clear. The engine will start and run fine for 5-10 minutes. Then it dies. If I let it sit overnight it will do it again. Last time I did this, I unscrewed the 2nd filter drain tap soon after it died. It sucked air in. No fuel came out after the hissing stopped.

Today's Featured Article - On the Road with Dave Gohl: Auction Musings - by Dave Gohl. I was thinking the other day about all the auctions I've been to in the last few years. There've been many. Some have been very good, some have been well, disappointing to say the least. But no matter how good or bad auctions may be, we always seem to stay until the item we've come for or are interested in is on the block. I've been to some auctions near and far. I think the furthest has been the Two Cylinder 7 in the Amana Colonies last year. Lots of stuff, lots of people. I've also atten
