Ok, made it to the lake this morning. The boat started and ran well untill about 11am. Then out of no where it stopped getting gas. tank was low, down to about 1 inch, so I added another 5 gallons. still nothing.
pulled the Brand new mechanical pump exit line, turned engine over no gas being pumped out.
Pulled the line end going directly to the tank, seemed empty also. I was able to blow air backwards through the line to the tank, reconnected to pump, and tried, still no gas pumpin out.
Removed filter from lines and connected lines, no gas.
Tank was cleaned to bare metal before this morning.
Gas lines, filter, and pump are all brand new.
so my options are the new pump went bad, or there is a bad check valve in the tank, or??? is there a filter screen in the tank? Any Ideas what to test, check next?

Thanks Cloaked, I will check the check valve tommorow. I already removed the filter from the system with the pump exit line into a bucket.

Other Issues from this trip.

1. New water pump exit line stayed cool ( I checked it ever few min for the first hour), but the temp sensor was dead. Where is the temp sensor on the engine? 1980 ford 351, pmc

2. Tack went high when engine above Idle, Ive heard this is possibly from vibration. Where does the tach lead connect to the engine?

3. Fuel Gauge was dead, Not sure where to start there?

4. Amp gauge was frozen / dead in the middle. Where does this connect to the engine.

All gauge fuses showed voltage on the voltmeter at the fuse box, and fuses were good.

Ideas and Pictures of locations would be a great help!!! Thanks.

Also, prop shaft Nut needs repacked, has a slow trickle,

5. It is back about 1 foot under the floor, I cant use a ratched, and there isnt really enough room to get a wrench on sidways, How do I losten it to repack? Is there a saftey coter pin or anything on the nut? or is it just compression.

The good news, No leaks in the hull, Not much vibration in the shaft, No Oil leaks, No tranny leaks, engine ran strong untill it quit, I was poppin the handle out of my friends hands all morning

Thanks for all the help!

I was having the same problems with fuel. I have a 79 S&S with the stock fram, water separator. If that seal is not 100% tight you will get air in the line and the siphon will be lost causing you to run out of fuel.

Ditto for me on CCOWELL. Mine is a '76 w/ 315W, etc If my Fram canister filter looses it's suction/siphon from the tank (loose Fram gasket or line is broken), the mech. pump won't pull it back - mech. pumps are just poor "suckers". I have a portable siphon hand pump that I connect to the fuel outlet just ahead (downstream) of the Fram canister. A few hand pumps and the fuel shows in the clear tubing - hook it all back together and go. Been there, done that a few times
It's a PITA for sure but it helps to understand the problem.
Good luck!

That is a good Idea, I have an old outboard ball I could slip on to see if I can get fuel out of the tank and up to the pump. I will check and make sure all the fittings are tight.
