Buying advice

When choosing a fuel pump spacer, verify the exact pump-to-vehicle distance required for your engine, as an incorrect spacer can cause cavitation or reduced flow. Consider material (aluminum vs. billet) for durability, and check if the kit includes necessary hardware or gaskets. OEM-matched parts give the safest fit, while universal kits offer flexibility for multiple models. Balance price with build quality to get the best value for your specific application.
