new switch for AUX tank... still no gas? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I replaced the switch cause I was not getting any fuel out of my Driver's side AUX tank- It has worked like a champ since I got the dealer installed option in 74 (its a 73 C20).

I disconnected the line at the switch and blew into the tank- the hose is clear as I hear it gurgling mightily. I am guessing it is a bad pick-up in the tank or clogged sock filter.

Is this a job better suited to a shop? I have fuel in the tank. I imagine I can drain it into sever 5 gallon gas can I have; but looking at the way these were installed, it looks like a nightmare (a rusty nightmare) to get the hardware holding the straps out.

What would a new tank INSTALLED run?
