you can get the barbed banjo from bosch its factory on the vw diesels for the injector return fitting that goes on ve afc style pump... since i have a bunch of vw parts i had a few laying around. . the 1/8 " silcone and zip ties held fine on my twin turbo truck that saw 50 psi pretty regular. .
the pump is definately getting full throttle the stop screw is there as a stop if i remove it its the same position.
