Anyone know what the pick up tube would be made of then ( copper?). Has anyone removed theirs? How?
I think my fitting is cracked and want to replace. Not sure how it is connected to p/u tube , ...
Any ideas/thoughts appreciated. Thanks.

pick up tube for what?
Sorry I just read your headline. It might be plastic, some of them have a screen that has been known to get clogged with gunk.

If it looks anything like mine, remove the fuel hose from the shut off valve. The aluminum block with the valve unscrews separately from the nut on the tank. Don't unscrew that or something is liable to fall off inside the tank. That will draw the pickup tube with it. Mine was plastic. As #jibes138 mentioned, it had a screen crammed up inside the tube which clogged up and ruined a 3 day cruise for us. Use an icepick to pop that out. Your fuel filters have many times the surface area of that thing so you don't need it.

Just a note about copper fuel lines, don't use them copper and zinc will react with diesel and form particulates which will clog the fuel system.

Thanks. Tube is 1/2 in or so thick walled but flexible plastic. Came out easily. Removed screen from bottom. Wasn't plugged.

If your electric fuel pump is the next item in your fuel system after the tank, be aware there is also a screen filter in that and it will accumulate gunk over the years and eventually kill your motor. Unscrew the bottom of the pump and clean or replace the screen filter. This applies to cylindrical style pumps that O'Day used on their boats. Ideally replumb your fuel lines so the pump is AFTER your primary fuel filter. This is easy to do, just get some fuel line and rearrange the hoses so the primary filter gets the fuel first. The parts can stay where they are just change the hose arrangement. If that pump filter is clogged you can change your fuel filters until the cows come home and still have restricted fuel.

Or it will accumulate gunk more suddenly, like when you’re motoring toward your marina being waked by a bunch of powerboats all trying to beat an approaching thunderstorm. The rocking will churn up the gunk from the bottom of the tank, and you’ll have no engine when the storm arrives. :yikes:

If the strainer in the dip tube is looking ugly, would one want to clean out the sludge in the tank that caused the strainer to fill with it? I mean cleaning the strainer will help but for how long? I can also second jibes138's point; that (Facet in mine) cylinder fuel pump strainer and its little magnet need to get a good clean out often, preferable annually or nearly.

Don't clean the strainer in the tank, remove it. Small amounts of gunk that will get sucked up will be captured by the primary filter.

And most importantly practice good fuel hygiene. Inspect and change filters, keep water out of the tank, and use a biocide like BioBar JF.

Dip tube screen was clean but removed it. Used thread sealant on fitting to tank. Removed the brass fuel shut off valve in line then bled engine. Tested diesel 1500 rpm for four hours w/o out a flutter.
Will install a new shut off valve to meet standards. Am thinking at this point it was the valve.
Thanks
