Have you tried Wes as classic diesel designs? His screen name is @Thewespaul .modified marine 7.3 IDI injection pump I was told from the guy i bought 4 of them from they are essentially a hybrid DB2/DB4 injection pump I will look it up and get the model and such DB2831-5090 1819681c91 1993-1994 MARINE 260BHP

and so you understand the 260BHP = 263.606HP so yeah that injection pump is putting out the juice. https://www.convert-measurement-units.com/conversion-calculator.php?type=power
I have 4 of these pumps and am down to only 1 left working and nobody can rebuild them sadly I have asked many companies and well they look them up and have gotten back to me with nope we cannot rebuild them theyre a specialty pump is what have been told.
