The BEST Option. Our ARP polished stainless steel Fuel Pump Blockoff and/or Water Neck bolt & washer bolt kits are exactly what people mean when they say "show quality." Made from ARP's proprietary "300" stainless steel alloy, they are rated at a minimum 170,000 PSI, which is even stronger than a grade 8 bolt! And, you can't beat the quality, shine and corrosion resistance of polished stainless. Nothing resists the ravages of weather, time and even repeated tightening and loosening like stainless. These are truly maintenance free! They also feature a reduced diameter 12pt head. Matching polished stainless washers are included. These can be used with either our billet aluminum or chrome steel fuel pump block-off plates, or our billet aluminum water necks. This is a great place to use stainless, since these bolts are very near the engine coolant, and this tends to be an area that is normally subject to excessive amounts of rust.
