Cub Fuel Line

[waynemo]

I want to replace my Cub fuel line from 5/16 to 1/4 inch tubing. Is that too small? It sure makes routing it on the tractor much easier and I have the hose and fittings.

Bear in mind I have only had a cub for a few months, but from what I've seen, 1/4 line should carry more than sufficient fuel. HOWEVER, given the rudimentary nature of the fuel filtration and the lack of a pump, I'd be wary of making the line smaller.

You will need the correct 1/2- 20 male to 1/4 hose barb fittings.

Same fitting for sediment bowl outlet.

Why change something that is perfection to something that is sub-par?

I understand that it is your tractor, you may do as you wish.

But the factory steel line is fine as IH made it.

Always jealous of the Cubs with the low dipstick. The tall one just gets in the way of EVERYTHING.

The tall on does not interfere with the gas line.

Hi,
PFord, below is a listing from TM Tractor for a new gas tube for Cubs with the under axle exhaust system, which I guess is what you have.
The listing has pics of the tube connected to the IH carburetor.

I'm not in need of one. It just makes getting to the carb/line a pain in the butt.

It sits right in the way of me getting to the nut on the fuel line at the carb.

Take the dipstick out when working on the carb. If you're concerned about debris getting in the breather, plug it with a paper towel.

Yea, that's what I've been doing. But that lower dipstick just looks so much easier! Any idea why it was changed?

FWIW, try removing the filler cap/dipstick. Also, if you loosen the fasteners on the carb flange to manifold it gives a bit of play to start the nut on the fuel line into the carb and helps to minimize the chance of cross threading.

I make all of the connections for the choke, governor and fuel line with the carb not mounted on the manifold and then move it into position. It is much easier to work on and the oil tube is out of the way.
