Which part number trim lines do I need?

[Unitoo1]

I have a Mercruiser 470 serial # 5656498. boat is 1980 mc-1 sterndrive with the eyehole on the top of the drive.. My trim pump is the old PRESTOLITE pump. I have reverse lockout with the clear tube and a black and grey hose.
I need to replace the lines. Does anyone have a part number for all 3? I have looked on many sites, but there are so many different ones. The lengths and bends are different. I would prefer a bit extra length as this is my first time doing this job.

I have not taken mine apart yet as I would like to use the lines to pull the new lines through. I have no clue how my bends look to match them up. Also, I don't know the lengths. So I am worried about getting the wrong ones. Nothing seems to say MC-1 like I was told mine is. Some say TR-TRS or R-MR. Alpha one, etc. I don't know which category I should choose. Thanks for any help guys!

Ok, had a look at the online drawings and yes, quite confusing. But I have a copy of an older Merc parts catalog, and on that it spells out which hoses are for the inline engines (like your 470) and the V8 engines (unlike your 470 )...

Here is a screen grab of my listing. You're looking for parts #1, #3, #4. You'll also need (a couple of) #2 as the old one is not re-useable.

AMAZING! Thanks so much. The ones I almost bought was from the same diagram yet different item numbers from evidently a different year or maybe the v8. So glad you found this!

I just pulled the pump off and changed the o-rings. Leaving the drive full up to see if it leaks down through the night. I might get lucky, but the outside of those hoses are brittle...
