Running out of fuel with the Howell system

At the risk of sounding stupid, if the tank is empty will the fuel pump still only stay on for 2 seconds at start-up? I don't hear any real fluid moving and it won't start. I set the timing after a dizzy install and it ran great for a few minutes then started to struggle at higher RPMs. Once it died for good I can't start it. I figured the pump would keep running until it built up pressure.

To answer your question, yes, the fuel pump will only prime for 2 seconds before startup, regardless of whether it has fuel or not. There is no fuel pressure sensor in the Howell system.

If you disconnect the fuel line at the throttle body, are you getting fuel?

This may sound like a silly question, but is there fuel in the tank? Made that mistake before...

I am going to put a good bit of fuel in it today and disconnect the supply line to see if it's pumping anything. I knew it was low but didn't think it was totally empty. Like most CJs of that era the fuel gage isn't the most dependable. Would it be worth my while to get a cheap fuel pressure gage to add to the dash?

I put 6 gallons of gas in it and primed the line. Cranked with no problem and ran great. Now I just have to give the Howell system some miles to learn.
