correct oil pump and scree

[LQQKatJon]

new engine came with a Melling M-22FHV. I would believe that to be a high volume. it also comes with a spring to increase the volume even more.
but the papers inside the pump does state that it is supplied with a pressure relief spring that is equivalent to O.E.design, and gives instructions
on how to change the pring to the "pink" spring from the green spring.

Anyway, I am not asking about changing that as the O.E spring I am OK, with as long as that is the correct pump.

What i do have a question on is the pickup tube and the correct one to use. This one has a bolt on port for the pickup, and my old pump has a press
in pickup.

checking the limited local part supply place that is open on a Sunday, I am coming up empty handed so far as to a bolt on pickup, and also trying to
assure myself I have the correct one for the toronado/GMC FWD pan.

any help is appreciated, I will be calling around tomorrow as well, if I can't figure it out locally.

Jon, if your original pickup tube and tube is surgically clean, AND fits
interference tight in the new pump body, it would be ok to use it. Be dead
certain that mixing the two results in positioning exactly where the
original was. Same thing goes for the bolt on tube and screen. Some of the
pickup screens are 180° turned from the originals. Some of that stuff is
easy to miss, and are super important. The last thing you want is for the
tube to suck air where it enters the pump, or to cavitate from having the
pickup screen turned around backwards.
