GM's latest way to connect fuel lines & some hydraulic lines have a plastic quick disconnect fitting, especially the hydraulic thow out bearing on a T56 transmisson. We wanted to keep the quick disconnect on the thow out bearing but needed for it to be able to run a flexline for AN -4 fitting. Solution.. We machine up an aluminum fitting!!! Pic are not that great but hope you can see what what we did.. Also will looking @ better way to get to the top bleeder on the throw out bearing.. Got plenty more custom fittings coming for this build.. We will be plumbing in the next couple of weeks!!
