I have a dual tank. Is the front tank internal or external pump?

If so, what is the other pump for?

Hello,

You have 3 pumps one in each tank that are low pressure pumps. The one on the frame rail is a high pressure pump.

Thanks so much for the quick response. I am thinking the high pressure pump is the one that has gone out. I have no fuel to engine, trying both pumps. When I do get it started, both pumps work. I can hear the pumps working and didn't think both pumps would go out at the same time.
Thanks so much for your help!
Mike
