The fuel line on the 901 went from the carburetor, up through the manifolds to the fuel tank.

Is there an update fuel line that runs out front so it does not route through the manifolds?

Thanks.

Lanexa Speedway has a nice picture of his version in this YT post.

The original line has a flexible rubber section for a reason.

Dad bought his 850 in 62, at was our main tractor till my brother sold it in 86, dad passed in 76.

Back then all fields where plowed before planting crops, that tractor was worked hard plowing, discing, pulling 3-14's in sod ground it would burn up to 5 gallons of gas pre hour (3 hours per tank), 6-7 hours per tank pulling 2-14's.
Numerous times stopping for lunch on a hot summers day I've heard the gas boiling in the tank. the fuel line was replaced once with another factory line due to a cracked fitting.

Not once did that tractor vapor lock or even lose power because of the line running thru the manifold.

Agreed, DS.

By definition, a gravity flow fuel system cannot vapor lock.

This is not to say that boiling fuel issues have not become much more of an issue post EPA/ethanol.

I am going to make new solid line for it.

Would you route it away from manifold if doing that, or duplicate existing route?

Most folks that make a new steel line route it in front of the tank bracket.

I use the OEM line on all of mine.

This is a topic of major debate here. "Vapor lock" in the gas line is often blamed for problems with these tractors quitting and not wanting to start. E-85 is blamed as being part of the problem, because it can boil in the gas tank if it gets hot enough. I have a 960 and a 901. The 960 never runs for very long because it is used only in pulling competitions. However, sometimes it will pull two long hooks one right after the other, so that will be a sustained heavy load which will cause the temp to rise, yet it has never had a fuel flow problem. The 901 was my raking tractor for many years. Raking doesn't usually take a lot of power, but on a long uphill on a very hot day the temp would go up some, and I never had a problem with that one either. With a fuel line that is pretty much vertical, I would see it as being quite a trick to keep a vapor bubble trapped in that line and to keep it from floating back up to the tank. I just don't get this rerouting thing.

If you wish to reroute the fuel line, you will need to bend your own.

The OEM fuel line, though expensive, works well.

"If you would like the fuel line rerouted it is a do it yourself job."

That has been my experience with the x00 series as well.

Usually they end up being closer to the exhaust pipe than original.

At least the originals were not on the collector end of the manifold.

There is no update. If you would like the fuel line rerouted it is a do it yourself job.
