I run 100LL in my FB with no problem, actually runs smoother idle's better.Shoot bigger flames..... It did smoke the first time for about 5 minutes. But i did pump some old gas that had just a tad of Jet A mixed in, not on purpose the tank i used to drain the fuel had residual Jet A. Great part is i got another 55Gal drum to finish. Had a customer come in who needed his fuel cells replaced in his 182, and no where to put that gas.

 

We run everything on 100LL. We have an old tug with a dodge 318 v8 in it that is running on 5 cylinders and we run 100LL in that. We also run our small snow blower on 100LL and our 86 chevy fuel truck. The chevy fuel truck was actualy a one ton, converted to a 3/4 ton, then converted to a fuel truck. Its so hacked up its rediculous. I have been working on it for the past few weeks fixing the stupid thing. Got it running pretty good so far. They installed a Holley Carb on it that is made for light cars and trucks Not for a 4000lb truck plus 650 gallon of 100LL. They also wonder why that engine doesn't run perfect.

I have only been working at the air field for a little over a month and I all of a sudden became the "Airfield Ground Mechanic". To much liability and to little money for me to feel comfertable with that label

They expect an engine that is built for low octane unleaded fuels to run perfect with high octane leaded fuels.

Jet fuel is nasty stuff!
