Whilst not being a huge fan of amazon and wanting to shop local i was in contact with some big guns at hhc about leakproofing my 6.0 hp system. They said they wouldnt hesitate to use alliant products as they dont carry the upper injector seals. Im still waiting on other parts and tools to do the work but research led me to bc deisel for this. Im hoping it solves my long crank issues. Parts were ordered on the 9th of july. Shipped on the 12th and received in good order to my door on the 14th. Being that im in alberta and shipping over border can be a pain its good to know i have the option from bc as im from nanaimo and do the run regularly should i need to do a pick up order.
