The inline filter must be one for a gravity flow fuel system, not a fuel pump.

Hi,
The original gas strainer under the gas tank works ok, unless the gas tank has lots of rust.
The strainer has a screen above the bowl and gasket to filter the gas, be sure the screen is there, and clean. It is shown in the 1955 operator's manual, on page 32.
If the gasket is old, it might not seal if you try to reuse it.

TM Tractor has a new gasket and screen for them.

If you put on an inline filter, use one made for a gravity flow system.
People on here have said that a filter for a fuel pump system can slow the gas flow too much.

Rudi, that did much work on this website, like the Cub manuals at the top of the page at Cub Info, used to say that the original type metal gas line is safer than a rubber gas line, less chance of fire.

I just installed an in tank vertical "tower" screen from Steiners in my tank. Screen is fine enough it should keep stuff in the tank and not circulating into the system.

And a word of caution about the sediment screen: Make sure the screen fits inside the glass bowl lip, so the lip seals against the cork or rubber gasket. If the screen gets between the glass lip and the gasket, gas will leak there. The original glass bowls have a slight recessed area just inside the lip where I try to fit the screen. So, from the bottom up, it's glass bowl, screen inside the bowl lip, then the gasket and housing. The Parts manual has the order wrong, showing the screen above the gasket.

Thanks for the tip. Maybe it would be best to remove the inline filter and go back to original metal gas line and bowl strainer because I am de rusting and resealing the tank. Never knew there was a different in line filter for gravity flow.

Hi,
Below is a listing from TM Tractor for a new gas line for the under axle exhaust system. You can look at the pics.
I guess yours has that exhaust system, since it is a 1959 Cub.
They are a different line than a Cub with a vertical exhaust system uses.
It has a bend to clear the exhaust pipe. There has to be some space between the exhaust pipe, and the gas line.
The threads in the gas strainer, and carburetor need to be good, and the original size, to use the gas line.

Thanks for the help. I checked the gas tank and it is really rusted. I think the first thing I will do is clean and coat the tank,clean the bowl and new inline filter before trying to adjust the carb. Then follow the What to do when bringing a new cub home, that is a great thread.

Good idea! However, an inline filter is not needed if you have a good clean sediment bowl on it.

Thanks for the tip...

Forgot to say earlier: I like your screen name. One of my favorite movies.
