[Supras] Oil Tube (From valve cover to block, 7M-GE)

[supraman88]

Wow. Toyota wants $40 for this 1 foot piece of tubing.

I put a reinforced heater hose in there, but a number of people have
told me the oil will break down the rubber of the heater hose, and the
alternator is pinching it.

The tubing is about 7/8" diameter. This is another job I only want to do
once, as it involves removing the alternator. Other than buying the tube
from Toyota (which I will do if I have to) anyone have any ideas for a
replacement? I've been to plumbing stores, looked through the Oil Burner
sections in some hardware stores, etc...

Thanks!
