Gas Tank Plugged up????

[Momboy007]

Hello All,
I am new here but have a question for all the been there done that folks.
My truck was running out of fuel, it has a 350 And automatic and is a half ton, anyway, I took the fuel line off at the carb and turned it over a few times and got very little fuel, just a slight drizzle. I replaced the fuel pump and it sent gas out good, then went for a test ride and it is acting up again, pulled the fuel line at the carb and it is only a drizzle again. I think the tank might be gunked up. I notice that I have 2 lines that run out of the bottom of the tank, one is larger than another, would this be correct? What is the best way to approach this problem, deal with it with the tank inside the cab or removed?
Thanks all in advance,
Rick

Also check your rubber fuel lines. The have the habit to collapse with the outer side of the hose looking good.
The larger of the two hoses is the feed to the fuel pump and the smaller is the return line from the fuel pump.
Oh by the way welcome to the board.
Since you posted this in the suburban forum I will move it over to the pickup forum for you.
