Hey everyone, my 390 Motor Yacht has four Groco strainers in the engine room. One for each Cummins engine, one for the genset, and one for the AC. My boat came with a Perko-brand spanner wrench with two sizes of pins which I normally use for the deck fill caps. I assumed it would work to loosen the bronze strainer caps too, but the smaller size pins are too big to fit in the holes in the strainer caps. I ended up using a pipe wrench, which is not the ideal tool. Do I need to buy the Groco-brand spanner wrench? Seems weird to have a need for so many different size pins in spanner wrenches.
