I have 6 in total, 4 Ford 1680, 2 Marren 1680. The Fords have about 1200 miles on them and the Marren's I am guessing are about 6000 miles. They all come with brand new o-rings. They all function perfectly, I am selling them to try a different injector for my setup.
I would like $120 shipped per pair or $320 shipped for all six.
