2010-2024 Toyota 4Runner Fuel System Parts

The 4.0L in the fifth-gen 4Runner is famously reliable, and a lot of that comes down to how well the fuel system holds up over time — but fuel pumps, injectors, and filters do eventually wear, and the symptoms are gradual enough that owners often don't notice until something forces the issue. Staying ahead of that is what 2010-2024 Toyota 4Runner Fuel System Parts are for.

 

High-mileage fifth-gens benefit more from a fuel pump inspection than most owners realize, since the in-tank pump on these trucks runs continuously and its output pressure drops slowly over years in ways that hurt performance before causing an obvious failure. Injector cleanliness matters more on builds with performance intake and exhaust work since the calibration assumes a specific fuel delivery rate.
