I generally stopped dealing with PP because they always seem to fill the order wrong - for example they substituted windshield washer tubing for injector return hose!
Later they accepted an order for Winter Flow fuel additive and then backordered the product until May - when you don't need the additive any more.
Much better prices available - so I don't deal with them unless they have something that can't easily be gotten somewhere else. Been at least a year since that's happened.
The catalogs are good parts references though.
