Thought you guys may be interested in my veggie mod. Its not a 190 but close enough  The initial idea is simply to have a second tank to increase the range. Travelling across borders with waste veg oil in containers is illagel without a license for each country. This isnt technically a 100% ideal solution but it at the very least shows we are not planning on dumping the oil in an austrian stream somewhere I have used a plastic water tank designed for campervan water storage so I wanted a setup that ensures no fuel from the main tank will get into this tank which is not rated for fuel. This avoids any risk of diesel or paraffin getting in it. I chose this setup for cheapness. Cubby hole with carpet cut out.  Bugger, doesnt quite fit, where is my mallet  Lid doesnt quite close yet, will do when I find my mallet  Neat little pipe heading off towards the filler neck, this will go through a neat hole under the boot floor when I get around to it.  Enough space for the pump and a filter plus room for my veg related stuff (spare canister filters, priming paraffin, marigolds). The main reason I chose this particular tank was obviously its size but also the huge inspection lid thats perfect for pouring out of large containers that veg oil comes in. No more funnels or stains down the rear wings  The output from this tank connects to the breather that connects the main tank to the filler neck. It turns out the breather has a one way valve in it so the fuel from this tank works its way UP the breather pipe and into the filler neck. So I have ordered a pump (£10) as syphoning is way too slow due to the height of the filler neck input. At some point later I will be adding a whole house water filter type setup so as the fuel goes from tank 2 to tank 1 its filtered down to 5 micron, so I can just collect dirty veg and as long as I am confident it has no water I can just shove it in the tank As you can see from the pics, the tank doesnt quite fit due to a ridge. I intend to use the 'clout' method to persuade this ridge back to a sharo corner so the tank will drop and the lid should close. I also intend to drill a hole so the pipe will run under the boot floor rather than above as it does at the moment. The joint to the main tank is currently made up in copper, metal causes veg to oxidise so once the setup is complete and I stop fiddling I will switch to plastic pushfit. (pipes are all 15mm). |

what, stick a box in a hole ? Its not that hard, the hardest bit has been getting my head around the existing setup and making decisions about how to connect up to it. I better get a pic of the tank connections I guess to finish this thread off

Did you get the second tank set up? I'm thinking of doing the same. Filling the tank is much easier on the 190 than the 300td. I use 4 litre bottles but the handle of the bottles get in the way on the 300td! I like the massive hole in the middle. Ideal for pouring into! |

yep, all setup, in order to not break the rules for taking abroad and on ferries I dont have the 2nd tank permenently connected, I have a hose that I stick in the filler neck and then pump it in. I will post some pics later. It works pretty well, the 2nd to 1st tank operation takes about 10 mins for the 40 litres and doesnt involve getting any veg on me. |

I take the cap off and stick the tube , around the rear wing and in the neck where the fuel goes. Then pump away using a whale style 12v caravan water pump (I checked and it has nitrile seals not rubber) powered by either my 3rd battery (yes, third) or the lighter sockets I wired up in the boot that connect up to my 1st/2nd battery. A pic will show it all but it was raining and the boot is full of wheels and furniture at the moment If you do decide to cut into existing fuel lines please do contact me, it doesnt work quite how you would expect. The small line coming up from the tank that rejoins the neck about half way up actually has a one way valve somewhere down the bottom. So if you try to fill using this method you actually block the vent and will get all sorts of problems. |

new pics for those in the veg wagon club Oops, could do with a clean  All tucked away, no officer, its a container for 'edible oils' perfectly legal (apart from the waste aspect) and not against any ferry rules.  My little pump, It was about £15 and designed for pumping water in caravans, it has nitrile seals (veg eats normal rubber) and so far works fine. Whale do a similar one which is also fine. I have a submersible whale one for going direct from containers into the tank but I dont use it much, I just pour them into the hole in the 2nd tank.  And here it is filling up, if I want to be stealthy I can close the bootlid and its all very subtle.  Obviously I have a bung that goes in the end of the red tube when its not in use. |

You do need a big mallet to get the tank to fit and there is a little more work to do, in particular a vent arrangement. I also intend to put a 1micron whole house filter just before the pump, so all fuel in the main tank has been filtered at home and then again down to 1 micron. Another benefit of this tank is that you can squeeze up and fit a 7inch sock filter in through the lid of the tank so you can filter used oil directly into the 2nd tank when on the move. Its not ideal because its not very deep so filtering takes ages, pouring a bit, then waiting a bit etc, plus your then left with a stinky sock filter to carry around with you but its nice to have the option. |
