    Worked perfect

    Had to remove some of the oil rail ports to evacuate the oil prior to injector removal, figured the original o-rings would be toast. These fit perfectly to replace the 23 year old ones, felt very sturdy.

    I installed the oil crossover and it worked great. After about 2 years one of the O-rings split, probably due to the excessive heat and such. Technical support from Riffraff was great when I called them. Ordered some extra O-rings for the glove box and I'm good to go. Definitely should order some extras especially when you're pulling heavy across the country a get a leak. This is a great company and I will continue spending money on their products.
