We've used "tons" (not literally) of the M-19 pump's from Melling, not one single issue with any pump we've installed.
If you need a H.V. pump you have other issues. I also don't trust any other brands, I recently "battled" a vendor over some rod brgs for a Desoto, "Made-in-Taiwan", never again!
Thanks, Gary in N.Y.
P.S. If you have ANY oil pump questions feel free to contact George Richmond at Melling. You will get straight answers and no B.S. He can be reached at
