[RedSabre]

I have injectors that I am trying to find out what the brand is and their size. Since I did not build the car and the builder is of no help, maybe someone out there can. The numbers on the side reads D1720W, they have a black body with a green color band on the barrel. I thought they might be by Lucas but my Internet searches have gone no where. The previous owner/builder said they were Bosch which does not use that series of numbers. Anyone have any idea?
