The Stovebolt Site Forums The Shop Area General Truck Talk Replacing Gas Tank

I had used a por 15 kit to redo my original 54 tank a few years ago. I now get rust in my fuel filter and have been changing them out too often. I changed the quadrajet filter and after doing so I have fuel all over the intake. I assume I stuck something up inside it as I can't bang on it to unstick a float as I had thought.

So I have a pal who is giving me another q jet. Instead of going on with the rusty mess I ordered and just received a chevy duty replacement tank and a new fuel sender and gasket.

Is the old carb so full of junk that it needs rebuilt and if so is a qjet hard to do?

Other than a float sticking what could it be?

Should I replace the fuel pump too?

Blow out the old fuel line or replace?

Any tips would be appreciated.

PS Chevy Duty tank is made in Taiwan

Qjets are actually pretty easy to rebuild. It is probably the needle and seat that are clogged up with sludge. Just take your time. Doug Roe's book on Rochester carbs describes the Qjet in detail.

Q-jets are pretty easy to o-haul. If you just have some object in the needle & seat pinch off the rubber fuel line & start the engine & run it till it dies. Than remove the pincher & restart the engine. This will usually flush the foriegn object though. Put an inline fuel filter in the line between the tank & pump. What part of Missouri are you from?

Thanks to both. Wrenchbender I'm in Jefferson City. I'll try that. If it fixes my problem should I just use that carb after replacing the tank or will whatever is in there (crud) just dissipate? I can get my friends carb for free and he says it is a good carb that he took off of a 327 in his model a roadster. He went to a 3 2 set up and then sold the car but still has the carb.
