Post Throttle response in 37 EFI
New to the site but any how, Ive got a 37 EFI Mud buddy with 68 hours on it. Throttle response seems to be getting slower and slower im thinking I need to start with the fuel filters first then pumps. I'm almost positive it has to do with fuel delivery or possibly bad fuel. I've had no other problems with it other than this. Just looking for a second opinion or insights on the issue.

Check valve lash, and check fuel line connections. If you do a lot of idling the plugs way have some buildup. Also observe when you turn the key on the fuel pumps run for 2 seconds then shut off.
If problems persist send it in for warranty service.

Got it fixed this am . Put hose clamps on the fuel line were all connections are made instead of the crimp things.
Thanks for the help guys
