For those of you who might recall, I have had an ongoing problem with fuel getting to my port engine. I had replaced the fuel pump, fuel lines and both fuel filters to that engine and it seemed to work fine for a short while. However, yesterday I took her out to the local island and upon trying to start, the port engine ran for maybe 30 seconds and died. After several crankings, I switched to the other tank and she started. Switched it back to the original tank, and she ran fine the rest of the day. Today, I removed the fuel line from the tank, and anti-syphon valve. Found some gummy residue, valve seems to be working fine. I tried to remove the pick up from the tank. There is a welded threadlet with what appears to be a SS fitting screwed into it. I was unable to budge this fitting even after soaking for an hr with PB blaster. I can see no threads on the fitting and wondering if it is even removable. Can anyone shed some light on how this fitting is installed in the tank?
 
I would pull the pick-up out of the affected tank and see if there is anything wrong there. Sometimes there is a rubber extension and screen on there that may rot and fall off.

Kenny,
I think he is asking how to do do that.

That's my next move. Gonna take my 1/2 breaker bar down with a persuader to try and loosen the fitting-if that's what it is. I'm just afraid of twisting off the thread o let or whatever is installed in the thread o let. The way my luck runs, whatever is there is not removable. When I had new tanks fabricated for my Mariner, Matson tanks installed a dip tube-tack welded to the bottom of the tank. There is nothing to remove. I was hoping Carver did not do something similar to what they did.
 
Be carefull. I'm not familiar with your layout but my boat would require puling a motor to replace a tank.

OK, so I went down to the boat tonite with a large persuader and the fuel pickup fitting came off easily. As I was removing it from the tank, I felt a resistance and even though I tried wiggling the tube, whatever was on the end came off. The pics below show what I found. There is about 7 inches from the top of the copper colored part of the pick up tube to the bottom of the tank. What was on there? A rubber tubing? I'm hoping Absolute can shed some light on this. Can I just put a piece of fuel line with a bologna cut at the bottom?

Yes, you can splice on to the end of the metal tubing with what ever you want (as long as you can get it pass the threaded coupling). We see where some tanks have a piece of poly tubing that actually lays on the bottom of the tank but most are cut a little short and usually have a scarfed cut to the end.

Had a call to a shrimper where the boat yard had custom fitted the pickup - poor guy would fill the tank, go out and run just fine. On his way back in the boat would act like it was running out of gas - the custom fitted pickup being square cut on the end was hard against the bottom when the tank was half full but had ample clearance when full, another reason we carry a sawsall.
 
Thanks for the info Luther. Will a piece of fuel line work or is there a better product to use?
 
Some of the center console boats have a poly tube for the pick up and rather see that then the normal rubber fuel line.

Maybe try Goodyear Rubber on Central Ave in St Pete and see what they recommend or there is a welder we use in the Bay Pine area that makes fuel pickup any length you need.
 
Thanks for the info. I'm very familiar with Goodyear on Cental Ave. I'm not sure I know what you are referring to when you say poly tubing? Can it be pressed onto the aluminum tube and stay there without any clamping and will it curl like regular fuel line?
