PS Pump Return Hose

Will fuel line work for the PS pump return hose?

Depends. In the past, that would eventually cause the hose to swell and get spongy. You had to use specific hose rated for oil.

But not that long ago, I went to the parts store and told the dude I needed 3/8" rubber hose for oil. He cut me some hose and when I got home, I looked and realized it was labeled as fuel hose. When I looked up the number printed on the hose, it turned out that it was rated for oil too.

I went out and looked at the number on some that I have, SAE 30R6 KX, and looked it up and sure enough, it says for gas, diesel, and lubricating oil.

Im using fuel line for my PS return when i put a filter in. I didnt research it before hand, but its been used successfully for 5+ years on another application, its from the same roll. I will do it again when i put a cooler in, but it was the only 3/8 hose i had.
i only have 15/32 trans fluid line
