Does after-market fuel pump void VP44 warrantee?

That is a good question. When I got my 370's from piers there were a couple sets of washers and i wondered what the difference would be with the different thicknesses. Would this affect timing any? Would there be any performance or mileage benefits?

I played with three thicknesses when I first put my 370 injectors years ago. The best power & least amount of smoke & best MPG came with the thinnest ones . 020 If I recall correctly.
 
Yes this topic has been tested and researched before. If you do a search you may come across a few post from Joe D. , Piers, and others on this topic. Bottom line is the . 020 work best.
