Apparently I'm too dumb to operate gas line wrenches! With a new fuel pump to fuel line flex hose, the 1/2 9/16 won't go over the rubber hose size. Plus the 1/2 won't fit on the 1/2" fitting. Actually any fitting seems a fight. Closer tolerance? They are Sears tools

They only fit over the steel tubing that corresponds with the nut.
Most likely the only option is open end wrench.

Some fittings are made off shore and made in metric wrench sizes.
Been going on for a while.

You might have to do a little custom grinding on your wrench using a cut off wheel.
That way you have a designated gas line wrench.

Also there is not much of a angle to the head?

If they are Sears Craftsman tools, the culprit is very likely the size of the fittings as suggested above.

I have some older but barely used Craftsman flare wrenches. Interesting to me is that they'll really only fit on a brand new fitting. Any kind of dirty, used fitting I have to grab one of the made in China wrenches.

The fittings are nearly always 12mm or is it 13mm? Regardless, the repops are not made accurately. You'll need to use a metric wrench.

Flare nut wrenches are typically a very tight fit. Any deformation will prevent the wrench from fitting. And has already been said they normally only fit over metal lines. The rubber hose would be larger than the slot in the wrench. You will need to use a regular wrench or modify your flare nut wrench just for this purpose.

thanks

I've checking the rubber fuel line hose from Carpenters. They are 1/2 and 9/16, not metric

I replaced my gas line to fuel pump flexible hose and had a similar wrench size problem. Not having metric flares, I recall thinking that flare wrenches had yet to become standard and I sucessfully used a crescent wrench.
