Thanks

When i put pressure to it I found the drip. I installed new fuel line. | | | | | Joined: Apr 2005 Posts: 381 Shop Shark | | Shop Shark Joined: Apr 2005 Posts: 381 | The fuel pump diaphragm isn't holding the pressure probably due to age or deterioration due to ethanol in today's gas. Hence it's allowing the fuel to drain back. Try rebuilding the fuel pump with ethanol resistant seals etc. | | |
