I have searched and found nothing. I need a locking fuel cap on my MF1529. I think I might be having fuel stolen. Has anyone put a locking cap on the tractor and where did you get it? Thanks in advance!

In the foggy, distant past - one of my vehicles had a locking gas cap. It kept getting water past the sliding key hole cover and freezing. Required a "hot hand" on the cap to release the frozen sliding cover and then a "hot key" to un-freeze, un-lock the cap.

Obviously - I never had stolen fuel. Finally, had enough and replaced it.

BTW - you might want to try Messicks or visit your local MF dealer.

You probably could, but most tractors have fuel lines that are easy to get to, so chances are good if someone wants to fuel, they can just cut the fuel line or slide it off and then slide it back on.

You need to set up a critter camera and catch the animal sneaking around your equipment. If they are willing to steel fuel, they will do other things too.

Got one up already waiting to see what takes the bait! I was telling my neighbor about it yesterday evening and it turns out his son’s (who’s off to college) car can’t keep gas in it and he couldn’t find a leak. Now he has a camera up too.

I have a locking cap on my aux tank, but do not lock it. I'd rather them steal the fuel by removing the cap. Any other way will be more expensive to repair than the cost of fuel stolen. But, i also don't have a problem with fuel being stolen, if i did, i may think differently.

Have a friend who found simple solution. He placed a 5 gallon can easy to see and it intercepted the person before getting to his fuel tank and filled it with aviation fuel. Said the octane level was high enough it would burn up most consumer engines. Now if diesel fuel and you use off road and they are using in an on road vehicle if you could get the law to test the fuel they could be facing right high fine.

He’s wrong about the octane part. I’ve considered leaving gas cans out with mostly water or mixed with sugar.

I got mine at NAPA, if you have one near you. They have a catalog that cross references the cap.

Don't know how aviation fuel would cause problems... we have a number of folks who come to our airfield specifically to purchase avgas for their small gasoline engines --chainsaws, snowmobiles, ATVs, etc. The fact that avgas (100LL) doesn't contain alcohol is why they like it, in addition to the higher (100) octane. The LL --low lead-- doesn't seem to bother.

I agree with the game cam -- I really have a problem with folks who steal from others.

100LL aviation fuel, is actually only about 96 octane, if you measure it with the automotive fuel octane method, R+M/2.

No, 96 octane gasoline will not do harm to a gasoline engine. Though the lead in 100LL could cause issues with catalytic converter(s).

Many aircraft which were actually built to run on 80 octane, have been running 100LL for decades.

Too low an octane, can cause detonation, (knocking). Too high an octane, only results in money being wasted.

The octane an engine needs is basically determined by the compression ratio. Although, with electronics engine makers have been able to push those limits.
