7275fuel line problem

[paul harris]

I have a cub cadet 7275 tractor it seems like air is getting into fuel lines. I read on this forum about a problem with fuel lines
rubbing or cracking on these tractors but can`t find it when i do a search, has anyone heard of this fuel line problem

thanks P H

You would notice fuel leaking from the lines- mine rubbed through on the firewall on the injector side of the engine where the lines come up from the rear
Mine ran fine but fuel was spraying everywhere thats how I found it and that was 6 or more years ago
No air in the line issue though

The hoses can actually have cracks in them that won't leak fuel but can allow air to get in. If they're cracked replace them.
