Just going off memory but I don’t think a lash cap does anything to make a lt4 pump flow more. It just moved the piston up in the stroke and may risk bottoming out the piston if it isn’t just right. I had some posts a long time ago about it.

The lash cap is suppose to help with the smaller base circle high fuel pump lobe cams. Without it you have some wasted cam lobe where the piston isn’t moving.
