Re: [DML] Fuel distributer o-ring



Please re-read my post. I added the copper washer to the hollow fuel bolt on 
the fuel distributor on the line from the frequency valve which sits at the 
end of the hole where the PPS piston o-ring is. I'm saying the fuel bolt, 
being perpendicular to the PPS is protruding into the PPS piston pathway and 
by adding a copper washer to the fuel bolt has returned the bolt to the 
correct depth.
