Evan I actually though about it after I finished all 6 delivery valves and collected over a gallon of diesel on the ground...LOL. If I have to go back in that's definately the way to go. By the way I am still putting back the manifold etc. so have not started the engine. ... In order to help centre the spring. I placed the spring in the delivery valve with the little round assembly and the crush washer, I was then able to slip the entire assembly into the body of the injection pump by putting it into the hole sideways then standing it upright...seemed to work fine for me but only time will tell...
