Hey everyone,
I'm on the hunt for a replacement short fuel jumper line for a Detroit 6V53. It's the short style with the fixed 3/8" inverted flare male threads and the smooth bullet-nose pilot flare tips that slide down into the injector.
The updated factory part number is 23504074 (sometimes stamped under older casting numbers like 5129623).
Dealers are quoting crazy factory lead times/prices and general local hose shops can't stamp that bullet nose style tip. Does anyone on the board happen to have a clean New Old Stock (NOS) spare or know an independent warehouse or marine salvage yard that still has these sitting on a shelf?
Appreciate any leads!
