Filling the tank is enjoyable again! Especially since I started to assist local car services to get rid of the fuel from people who selected the wrong fuel. J So I asked local car services (it is quite often that people take by mistake the hose for super-gas instead of super-diesel or vice versa and unfortunately the new engines can react critical to those mixtures). Some rejected my request because some of their employees use it for their e. g. old tractors or they use it for their own fleet of older cars, or they claimed that they need a confirmation how the fuel was disposed. But three were really happy about my request because the companies taking care for their disposals didn’t fancy taking the mixture.
The only problem is, that you don’t know the ratio of the mixture of diesel compared to gas. To measure that ratio of the “soup” you can use an aereometer. Mine is from Thomas who sells them in Ebay (in case of interest please feel free to contact me for contact details).
The aerometer I am putting into this cylinder, which I have glued at a folding meter stick. This allows me to get a sample of the soup even out of deep tanks plus I can measure the volume roughly by checking the depth of the tank (filling).
The conversion scheme below allows me to find out the relationship of diesel compared to fuel. Up to 20% fuel is no problem for an old style diesel-motor, in the past it was normal to add gas to diesel in winter to improve the flow behaviour! Logic that I have to add regular diesel from time to time to maintain the ratio. 20%is for me the maximum because otherwise the greasing of the diesel for the injection pump may get worse (the diesel is responsible for the greasing of the injection-pump cylinders). By adding 2-stroke oil in a ratio of 1:50 PER GAS-VOLUME I am ensuring that the greasing of the „soup“ will be more then sufficient. This and the ext hint came from a friend, Oliver Neumann from Evotech, who is experienced in tuning motors. He as well warned me to use standard vegetable oil to improve the greasing factor.
Volume of diesel in gas:
00% - 0,720
05% - 0,726
10% - 0,731
15% - 0,737
20% - 0,743
25% - 0,748
30% - 0,754
35% - 0,760
40% - 0,765
45% - 0,771
50% - 0,777
55% - 0,782
60% - 0,788
65% - 0,793
70% - 0,799
75% - 0,805
80% - 0,810
85% - 0,816
90% - 0,822
95% - 0,827
100% - 0,833
To pump the “soup” into the tank of Big Foot I doing with a cheap pump driven by an electric drill, it manages to pump up to 2.000l / h. There is a warning not to use it for gas, but first of all it is not pure but as well diesel which does not light that easily and so far it worked without problems! And if the pump really fails because the sealing or so is worn off, who cares, a new one only costs EUR 10,-.
It seems as if she does not like too much to run without fluid for a longer time (the first one is now damaged after sucking the “soup” from a 1 m lower level) – I will give another one a last chance!
NB: The second quit as well and therefore I now bought one for EUR 40,- from Faie, which is OK for fuel duee to the specs.
With a ball valve and a switch at the end of a cable in between a short cable extension I built a kind of tap.
This shows the cable, which comes from the end-switch and goes into the cuppling of the electric extension-cable and switches off the power. For operation I put the electric drill into permanent mode, put the end-switch into "on" and open the ball tap. Some of the older jerry cans of the car services are rusty and so I put a funnel with a fine strainer into the truck tank. To be able to stop the filling process or to reduce the volume directly at the tank if the strainer gets stuck I built this construction.
The strainer in the funnel didn't work and therefore I bougth this one from Hoppe dieses which can be put directly into the tank nozzle.
