Sounds leggit. Thank you. It has two blanks fitted. Never really paid antention of the fiter fittings, other than put incoming and outgoing ports right way. I tought that there may be some other clever options. Like there is a "one-pipe" system for oil furnace burner here. It has one pipe from the tank, but there is filter and water/air separator unit that has in/out ports for the burner. I'm thinkking of mounting this fuelfiler unit such way that bleed screw becomes highest point of the pipe work. All in line of the fuel feed line straight to the injection pump. Then one continous return line from the injector back to the tank. I have been reading that there is available two different type of filter for this one "red" 30 micron and "blue" 10 micron, which former seems to be often used for gravity fed system. I have seen some talk about even finer and more specialized filters....I don't think I need to venture there with this engine. Other thing is a fuel tank. Original one is a bit too small. I went to check cheap engine external tanks, but they were very basic and looked like would lack durability. I check the innards and: * Caps had very basic seals, not even sure if they would survive diesel * Suction pipe was rigid corrugated plastic pipe, no weight, mesh or anything * No provision for breather This looks really nice, but really expensive too for small cheap diesel: http://www.vetus-shop.com/vetus-fuel-tank-diesel-25-litre-p-1783.html Pekka |

On mine, rather unusually the injector leak off pipe runs back into one of the tappings on the filter rather than back to the tank in it's own pipe. :scratch: Looks to be original and seems to work, however I think that originally it had a gravity tank rather than the lower level pumped one that I will be using. I think that it's a case of observing and seeing what happens. :coffee: If need be there is a spare 1/4 bsp input to the tank that I could route it to. |

Pekka, Vetus is a familiar name from back when I was a boat builder. But that tank price is outrageous! I hate to tell you this because you'll think I'm nuts, but back in my ultralight flying and building days, we just made tanks out of heavy wall polyethylene (polythene-Br.?) portable carrying gas (petrol) tanks. There was a round barrel shaped variety (Eagle brand) that seemed a lot stiffer and thicker walled than the usual rectangular jerry can shape. Anyway, the Vetus must be close to $300 Stateside, and a gerry can would set you back $15 to $30, and both are made of the same material. There are grommet mount fuel shut-off fittings that you can add to a portable plastic tank to attach the fuel line to. You drill a specified hole size in the tank and put a special grommet around the tank fitting and push it into the hole where it locks in place. The tank should be heavy wall, where you add this -- some of the latest fuel tanks are paper thin in the sides. http://aircraftproducts.wicksaircraft.com/category/fuel-valves (see tank mount valves near bottom of page re. Vetus tank : The main thing that degrades polyethylene is sunlight, so if you protect it, it should last forever. Most fuel tanks are black poly, but the Vetus isn't even that! Most gerry cans are red (petrol) yellow (diesel) or blue (kerosene -paraaffin) here. If you spray paint poly tank with black paint, it doesn't stick well (can be scratched) but in a stationary use, will be unlikely to be disturbed, so should last. Or you could encase it in something else, like tin or wood. |

I have been looking spare/auxiliar tanks they seem to be made out of HDPE, some with thick walls (regulation on EU). Wish I could find one with two caps or find a way of mounting unions on them. --- Quote from: vtsteam on December 21, 2014, 10:09:03 AM ---There are grommet mount fuel shut-off fittings that you can add to a portable plastic tank to attach the fuel line to.

Just correct size hole, squese Viton gromment on and valve stem in? --- Quote from: vtsteam on December 21, 2014, 10:09:03 AM ---re.

I have been wondering those color codes, I see all color of spare tanks, even orange and new is blue (says alcohol/gas proof) but use seems to be random. In the army there were some colr codes, I was mostly conserned about drinking water. One color was red jerry cans. But cann't remember what they had. I'm thinkking of using boat aux fuel tank (HDPE) and go trough all seals and building the in/out pipe & breather unions. What do you think? Plan B is to accept that I need a fuel pump and make one of these: http://www.hsaoy.com/aggregaatit/Lisavarusteet/PA_Polttoainejarjestelmat/kuvat/PA.20JD.jpg Pekka |

I bought a tank off ebay that is rotationally moulded black HDPE with fittings moulded in. Surplus from a stand by generator manufacturer who has changed his design / layout. 60 litres so roughly 2 foot square and a foot tall. Chap has several and accepted a lower offer than his asking price :) |
