Hi guys - have a customer with a '14 Equinox/2.4 that has a leaking HPFP... I can get the pump right now but the one time use tube between it and the rail shows no stock, no eta. Why is it one time use? It's all stainless steel and doesn't look to have any special compressible material - just as ball ends with a captured nut. The dealer really couldn't give any good info on it.. Anyone have any details?
