I have a JD Gt275 with the Kawasaki 17 HP FCV540V engine. I am not getting vacuum or pressure to run the fuel pump which is new. If I prime the carb it runs great until it uses the gas up, then it dies. I have replaced the filter and the vacuum line to the engine. The pump is not pumping at all. I know I have a vacuum leak somewhere. Where should I Look or do next.

Hows the compression ? Has it been sitting ? It could have a stuck valve .What engine do you have ?Did you try putting a little gas in carburetor ? If so did it run a few seconds ? If so its a carburetor problem ! Remove and clean carburetor .You could also have water in gas this will cause the same thing you can look in the tank and if you see a bubble in the bottom its water needs to be cleaned out and bowl of carburetor also needs too be removed and cleaned,Try these and give me results,hope this helps !

SOURCE: Drive belt install on JD GT275

The bracket with loops keeps the belt in position when it is slack (disengaged). The bracket usually has to be loosened to even get the new belt on, the belt ONLY runs on the pulleys.

when you turn the key on to the run positon do you hear a clicking sound coming from the carburator? this tractor is equipped with a fuel shut off solenoid on the carburator if you dont hear the clicking sound solenoid is either not getting 12vdc or it is defective.

Hi
That is a fuel problem caused by stale gas you will need to remove and clean the carb with carb cleaner.
