Question on 1999 Suburban engine oil and transmission cooler lines

[mackguy]

OK, so I've been doing some reading and thinking perhaps I should have a plan to replace the oil and transmission cooler lines (Mine has KC4+KNP) lines since I don't know if they have ever been done.

Apparently there is a supplier quality issue with these items? Has anyone determined a reliable supplier and p/n, or better to just pull old lines and take up to NAPA and get new ones made on site?

I think your best bet is to pull them and get new hoses put on your lines--that's what I've done with similar lines. The quality of replacement parts these days is hit or miss.
