I was surprised by the China part of Delphi as I thought it was a GM mfg here....guess the buyer just has to sort it all out. Offshore isn't always bad...I'm told.....but I'm still willing to pay for USA quality. For the vendors..... Some tech specs even would help with pump pressure etc. Especially for the hobby guys like me. I thought " correct " replacement for a 6 cylinder 250 would take into account what the mfg. designed for use. That poor little mono jet float and needle seat combination was used to a gentle flow and suddenly it had a tsunami of pressure working on trying to start an underhood fire. Must be setup for those tons of aftermarket carbs used by many. I like the idea of giving the stock stuff some care and respect if I can. I should have paid heed to the old saying....if it ain't broke......
