I cracked the flange on #4 injector and am attempting to R&R with a different Model injector. Trans Atlantic Diesel shipped a Model BG (C.A.V.) injector and assures me it is equivalent to the Model YB (O.M.A.P.) which is what I removed. The return line bolt was threaded differently so I am replacing it as well. My concern is the two models have different setting pressures per my version of the Perkins Workshop Manual. Will this create a timing mismatch or does the pressurization rate make the firing time difference negligible.

FLASH... Large inventory of used sailboat equipment, parts & supplies at great prices. After a 10-year circumnavigation in a Westsail 43, the owners are now clearing out all the excess and getting back to life ashore. Outfit your boat with well-kept equipment and save yourself a bunch of cash in the process!
