Okay here are some pictuers of the pickup tube, and 90 degree elbow. The smallest part of the whole assembly is the long pickup tube section with the screen on it. It measures 1/2 inch O.D. Should I have a larger pickup butt welded to the bottom of the 90 degree fitting. Everything else it pretty big.

Look at the hole inside of the aluminum square piece at the top of the tube. How big is that hole? That will be the smallest part. Also, when the blue adapter piece screws into the aluminum square, how much of the hole does it block off?
We just make our own from SS. I use a 3/8" NPT x #10 adapter and weld a SS tube to it that is 1/2" ID. |

Why? The tank is metal. The existing fitting attached to the tube is metal. I've seen tanks with metal tubes welded in them. I don't understand??? I'm certainly not trying to argue, but I just don't understand what you are saying. Do you have a link to a USCG reg where it states that? I would like to know since every boat I have ever worked on has had some type of metal on the tank pickup, so that means they are all going against CG regs.

I believe my Fountain and buddys Cigs came with metal pickup tubes in the tank.
I do know that stainless braided fuel line is not USCG approved. |

my 253 checkmate looks to have the same aluminum pickup he is showing....not sure if it came that way(procharger as well) but looks the same...

The problem with that standard fitting is that the tube cracks at the threads. The fuel is constantly beating on it and the root of the thread is a stress point. I cannot tell you how long it took to figure out the first time I ran into a cracked one - just enough to leak air.
I used to drill the fitting to slighty under the OD of the tube and use a piece of tubing with no threads. Made it a light press fit (polish the end of the tube if needed) and either loctite or epoxy the tube in. I am a firm believer in better living through chemistry (and I do not mean the mind altering kind) :) I figured that was the best way to avoid any stress concentration. Never had one of those break.
