Custom tapered delivery valve set for 4bt & 6bt P7100 injection pumps.

These DV’s flow 60cc’s more than the 181 DV’s and about the same amount of fuel as a aftermarket set of 191’s or 024’s DV’s, with less bottom end smoke, turbo lag and heat. This allows you to run larger than stock DV’s for daily driving or towing. Dieseltuff designed this unique DV back in 2006 to give customers a smooth, high performance DV for the street.

No cores needed
