I have my OEM replacement outlet oil line kit, line, spring and brass fitting. Most of the research I have done calls for heat to get the bends correct. Any installation advice would be greatly appreciated.

I just did a 034av oil line over the weekend here. Bar and chain wasn't getting enough oil. Oiler was turned to max. Had a leak where the pump mates up to the feed hose that lays inside the bar lube reservoir.
I used a heat gun on it
And I doubt I could have done without it.
Cut the hose length at 3 inches.
Heat up one end and get the hose onto the pump before installing pump.
Install anti kink spring into hose
From there it's just a little finessing and I did use heat at this point also to help.
Get the hose all situated and bolt up oiler and install brass outlet (heat needed again)

Yeap what he said.a lighter can also be used for the pump connection.careful though you only have 2 chances with that kit.
Just as heat is required, too much heat will ruin the new line.
Someone recommended soaking in boiling water to soften. Supposedly there was also a homelite tube that works but is not as stiff? I have seen 034s running tygon and they seemed to oil ok.

I've tried the regular black stihl fuel line but it wound up leaking.

Would light heat from a lighter on the ends, and a hair dryer on the rest of the hose work?

Yes. Any heat will help. It doesn't have to be a heat gun.
But like what was wrote above do not overheat the hose because it could distort or melt the hose

Biggest thing is getting on the end of the pump.the hose is still flexible enough to conform to where it needs to be after the pumps installed.the heat generated after it has ran will set the form of the hose.

Going to give it a try tomorrow. Thanks for all the help

One other thing that tab on the gear likes to break off now and then.the gear may only be spinning partial crank shaft speed and not wide open with the clutch drum.
