Update: So half tank gauge reading was about half tank. After another 5Gal jerry can I was full to the top. So two 5gal cans got me to the top. Tank is 20 gallons. I did not pull the tube yet.
Not sure if this matters, but I noticed that my return line form injection pump Tees into the vent line just before it goes to the tank. I opted to do this since I didn’t have another hole in the tank. It used to be a gasoline engine tank. And those don’t have return. Heading to block again tonight after work. No wind and seas are lot calmer. It will be a straight 4h motorsail. Once I get there, fuel level in the tank will be down enough to pull the pickup tube and see how low it goes. Does anyone know if I need to bleed the injectors again after disconnecting the fuel line at the tank to inspect the pickup tube? My intuition says yes.

How much did you think you had before adding the 5 gallons? What did it read after? Did you top it off and see of the numbers added up? I agree it sounds like a plumbing issue with the vent or pickup. I hope your access to the tank is better than mine!

The tank was out (dried out and inspected) over the winter in 2011/2012. So was the pickup and sender at which time I don’t remember seeing any signs of corrosion etc. It might be good to mention that prior to 2012, I had atomic 4 (gasoline) engine. I put westrerbeake in the spring of 2012 after a full rebuild. I kept the tank. Hoses were all new. My primary is the Racor 230R Diesel Spin-On Series filter/water separator. I change that and secondary filter every commissioning. No signs of water whatsoever. Also fuel that comes out while bleeding is clean.

Sounds like time to pull and check it.

Two trips to Block island this year and at about the same spot, right where seas get a little lumpy, and on about half full tank, diesel sucks in air and dies. First time was pounding into 20-kts (not a good way to travel), second time with no wind but large confused seas. The first time I sailed and dropped a hook before bleeding the injectors. Second time I added 5 gal jerry can and after bleeding injectors in 6 foot swell got her started without a problem. Ran fine after that in same conditions. I guess I should check to make sure fuel gauge is calibrated, although I’ve been using it the past 3-4 years.
