Thanks for the info John, We just purchased our new(old) 1978 Columbia 8.7. The P.O. was the original owner and kept the maintenance up on the A-4. She is one sweet running engine. The boat lived the first 18yrs of its life on a fresh water lake and when the owners knew they would retire near salt water, they had the fresh water cooling added and I guess made the modification to electric fuel pump at that time. In my opinion, the shutoff is the ignition key. I had heard of that secondary filter after the pump and have visited both Moyer's and Indigo's web sites.. I will probably do that.. replumb to have the Racor between the pump and tank and then a secondary filter between the pump and carb. I have replaced all my fuel lines with CG approved shielded hose, plus I have wrapped the hose near the engine and exhaust with a heat shield jacket. I am getting a small amount of fume odor in my lazerett. I believe it to be coming from the fill hose outgassing, as I overfilled the tank and fuel sat in the 6ft length of filler hose for over a week. I plan to remove that filler hose, which goes up to the side deck and make a direct straight short run to my tank from the cockpit sole. My 20 gal tank is right under the cockpit, the fill point will be at the aft end and will allow me to double check my tank level with a stick. I fill with 5 gal jugs (cheaper than paying pump prices at the marinas). I checked my vent line and it is clear. The tank is tight, having been reconditioned and lined inside and epoxy coated outside.. tank is aluminum. I get no gas fumes in my salon, bilge or engine compartment and do use the blower!
Thanks for your help.
