Set of 3x Diesel fuel injectors X Zetor 4701 engine / 4718 tractor...

Set of 3x diesel injectors-  VA78S453d2638 Sold as SPARES OR REPAIR / for rebuild. Taken from an engine that was running until stripped, however had been sat for a long time prior to us listing the parts, these have been cleaned up and 'pop' tested in our workshop, all 3 seem to pop at a good pressure and display a good spray pattern however do seem to lose pressure over time. Would probably get an engine up and running in the short term but I think ideally they need a rebuild.  As removed from a year 1978 Zetor 4718 tractor, 2wd, fitted with zetor Z4701 engine and manual transmission Good USED condition
