Review on 🔧 R12T Fuel Filter Water Separator Complete Kit - Marine SPIN-ON R12T Filter Replaces S3240 120AT NPT ZG1/4-19 Fit 3/8 Inch NPT Outboard Motors For Diesel Engine With Four Fittings: High-Performance Filtering System for Superior Water Separation and Optimal Engine Performance by Shawn Xayamonty

Complete replacement bolt on block on my 2007 Mercury 5.7 (carbureted). This block is smaller than the factory block. The screw holes are narrower, so I was only able to secure it with one screw (making a joint that would fix that). Be careful with fuel lines. If you don't have rubber fuel hoses, you'll have to bend those lines a bit (not much) to get them in place. Also because of that tough line I had to use the old 90 degree fitting (which fits perfectly) instead of one of the new brass fittings for the filter outlet. Like the look. The seals work great, the drain below too.
