They fit different years. The pf46 fits on most 99-06 gm fullsize trucks and the pf48 fits most 2007 and up gm trucks. They have different threads so you can't put the wrong one on.

Is there a longer filter to replace the ac delco PF48E?

PF48 is longer. But, The PF48E primary performance improvement relates to the relief valve design. The PF48E has a compression spring loaded nylon poppet that outperforms the current valve design.Other benefits:Element integrity (collapse strength) is increased by 25%. This is because the nylon cores are perfectly round.Filter media, which is unchanged, is no longer potted in adhesive which blocks filtration area at each end.Filtration performance (efficiency and capacity) are both unchanged.The filter shell configuration is unchanged. Existing cap wrenches continue to fit.Hydrostatic burst and impulse fatigue performance are both unchanged.Relief valve performance is much improved and statistically more stable.Hot oil durability is improved by elimination of adhesive.Cold weather performance (-30 C) with dexos 1 oil is excellent.Improved level of robustness to water accumulation.Nitrile material used in the sealing gasket and the anti-drainback valve is unchanged.PF48E filters meet performance specifications as defined by GM Powertrain.PF48E filters will be used in OE production in the near future.
