turboram wrote:BC those appear to be vw delivery valves , and yes they are very restrictive. swap for ones without the reaction piston. On the other hand if you remove the shoulder or reaction piston the dv will keep residual pressure in the fuel line thus moving more fuel .
note the cummins ones have a little flat spot on the seat and vw ones do not. The vw engine will not run properly with the cummins dv's , tried it .
