Ijust purchased a 1985 catalina 426 looking for documentation on this boat. tank all tank systems locations senderrs etc. Any help? Jwcyacht
I just looked at a 426 we put a deposit on, fuel tanks are in the engine room, outboard of the engines and one under the aft. Cabin berth, if equipped? It was in the lower bilge not ideal however the bilges are nice and dry. The water tank was above it. 166 gal. It’s a single tank. Ours had two eletrscans for the heads so no holding tanks.
The main engine room fuel tank senders are accessible through removable panels in the salon floor adjacent to the side walls. The aft belly tank sender location should be through a small access panel near the forward port corner of your master berth.
I also suggest contacting Tim Sutherland at unifliteparts.com He may have the additional information you need. He is also a great resource for random parts and accessories you may need for the hull and running gear.
