TDI Pump on Bio-Diesel

The results of running bio-diesel through a VW TDI injection pump. Commercial grade bio-diesel is o.k. unless it sits for an extended period of time (30 days or more). Home made bio-diesel is not really worth the risk of using in your fuel system. Yes we all know that it is less expensive & the exhaust from your vehicle will smell like french fries, but come on do you really have the correct equipment to process it properly? If you do, then good for you & happy mixing. If you do not have the correct equipment you will damage your injection pump. The pump pictured (1st picture) is off a TDI engine. You can see the parts that are coated by the bio-diesel, the electronic actuator (2nd photo) is colored a light brown, rusty color from the bio fuel. The pump housing has a brown film on it, also notice the rust on the metering sleeve. The head plug, regulator & overflow valve also have bio-diesel coating them which resembles rust. Using bio-diesel is a great idea, but if you do not get the ph level right or if there is to much glycerin it, the results can be expensinve when it comes to repairing the fuel system. One last thing, notice the filter inside the coffee can, the wax type substance at the bottom of the can is actually commercial grade bio-diesel that has solidified at a temperature of about 35 degrees. How would you like to have that in your fuel system?http://www.google.com/custom" target="_top">
