68 Mustang fuel issue

Hi folks,

I’m attempting to fix my 68 mustang (289). I’m not getting fuel to the carb. I’ve changed the fuel pump, fuel line, and fuel filter. Still no fuel in the carb bowl, so I unhooked the fuel line at tank, stuck it in a gas can and I got fuel to the carb. So I’m thinking I have an issue at the rank. The line from the tank to the fuel pump is not clogged.   Can anyone offer me any suggestions on how to proceed?

On top of the tank, the fuel line attaches to what looks like a fuel filter but there are two wires attached to it. What is this? Sending unit? If so that is strange because there is no fuel gauge on the dash.   It was quite hot after trying to start the engine several times.

I thought about unscrewing this and by passing it to see if I could get fuel to move that way.

Any help guidance will be greatly appreciated.

Thanks,

Adam

I thought about unscrewing it and by passing

Awesome, I wondered if it was some sort of fuel pump. I’ll do as you suggest and give it a try.

Another quick one: as I said I replaced the pump with one from retail auto parts chain. I read later that I should have used a marine style one w a glass bowl?

I’m violating some federal regs?

Thoughts on that?

Adam,
Tom above has some great advice concerning marine fuel pumps.

Here's some good reading for more information on mechanical pumps.

Adam,
Yes, it's a good practice to ground the metal deck fill too. Make sure the other end is grounded well to the engine block. A Ohm check would confirm this.

What fuel pump did you replace? Another electric or the mechanical as recommended?

Here's a link to one place where you can get a Carter M60389.

Many places to choose from

I should mention, there have been some bad versions of this pump that eat up the new diaphragm real quickly and then you get to return it for another one .   

It's right here, I was just testing your sharpness today Pete

Myself, I'm as sharp as a bowling ball today
