Exclusive to Laser Tools! The 7174 kit enables the connection of a vacuum fluid extractor to the most common diesel fuel systems therefore significantly speeding up the process of bleeding and priming the fuel system after a filter change or whenever the system has been opened for service or repair. Saving considerable time particularly where entire fuel lines have been emptied during service or repair.

Compatible for use with existing Laser fuel system bleed kits (See Part Nos. 5262, 5567 and 5704). Significant time saving over hand pump systems.
