Also check if it's single or double wall construction?
If you have a scrap see if there's cotton threads in it.
(double wall is needed to resist vaccum)
"Pretty sure" run it with the cap off and see if there's a difference.....
The whine could be the pump cavitating due to the vaccum created when the hose collapses.
It's an ugly/cheap/fast way to make parts and this is why I think a piece of good setter ie: EN26 would work very well for this part and why I'd suggest Ti Niteride coating for wear resistance while keeping the core soft enough to not break.
Side story: Many years ago I have a 350 4stroke...
Syris: Ummm they're NOT failing from lubrication issues.
Even micropolished they're still have an open grain structure with little to no core strength seeing that it's a sintered part.
If the Trans was rebuilt paying close attention to end float on all the gears the stock part should be...
Poodles: That's exactly what I meant by impact loads.
I think/feel this is why Duane can run huge HP through his without failure because his trans is tight enough so the gear can't get a run up and smash into the thrust so it's only seeing a compression load and not an impact.
