Do not buy this product.
"This is the only product I have ever purchased from DPP that I was disappointed in. About 5 of the 12 nuts that it came in must not have been made properly because they WOULD NOT screw onto the injector silonoid. I ended up have to jimmy it up and use a combination of the old and new gasket. . . Very disappointed because if I buy something, I never expect to have to twist and bend it in order to make it work. Other than this purchase I love DPP and will be a customer for life."
