2003 bigfoot 50hp 4stroke efi need to pump bulb at high rpm to keep running

[turbo930ss]

Hi

Having a problem with lose of fuel at high rpm. If I pump the primer bult it will run fine.

I had a issue with the mech fuel pump failing and sending rubber into the high pressure fuel injection. Getting stuck in the float valve seat. I have changed the following parts.

1: both fuel filter low and high pressure sides.
2: new fuel lineto engine and check valve on fuel tank.
3: new mech fuel pump.
4: checked for air leaks but can't find any
5: cleaned out the rubber from high pressure fuel injection system.

Thanks

Scott
