So on our B7500 Kubota, we've been having some type of fuel problem (i assume). after the engine has warmed up and when we're working at cruising RPM's (2.7k) it will suddenly drop to under 500RPM, then raise back up again. Sometimes as frequently as every 20-30 seconds and other times only once or twice in an hour. it idles fine.
We've changed the fuel filter multiple times. changed the fuel pump. we have a replacement air filter, but the old one doesn't seem too bad.
i'm wondering if anyone else has had this problem, or has any tips.
if you need any more information that i left out, let me know.
Any help would be greatly appreciated,
Thanks.
