Fuel delivery issue on a 268
We did a week of boating in the Sea of Cortez last month and we had a fuel pressure problem on our 268
I have a 502 motor so there is no engine driven fuel pump. We use a Carter electric pump. We draw from the tank, then the filter, fuel flow sensor, then the pump, then the carburetor. We have used this setup for 15 years in all kinds of temperatures and conditions. It has always worked well.
The 1st and 2nd day out, it worked fine. Third day, I noticed the fuel flow down to 12 gal/hr when it has always been at 16 at cruising speed. Sure enough, it started slowing down. We have a fuel pressure gauge on the engine and the gauge showed 0 pressure. We continued on at a slower speed for the rest of that day. That night, I changed the fuel filter and a new electric fuel pump. An hour into the run the next day, it happened again. We tried different things over the next 4 days but it was always happened again.
The question is about the tank. Has anybody had the fuel tank pickup tube out and what is at the end of it.
Any other theories and suggestions would also be appreciated.
