Have an older Super pump and looking to add some bling? This anodized aluminum ALDA cap will fit the bill. It is perfect for Mercedes M pumps with an outside ALDA kit installed. In addition, it will fit MW pumps for those who are choosing to delete the ALDA for immediate fuel delivery. Naturally, we recommend a pump build over an ALDA delete. This product is not recommended for upgraded MW pumps as over-fueling will occur.
