These lines are leaking. Plastic fittings break and for the time it takes to change them. Don't waste your money.

Money down the drain. The O-rings are too big and the plastic breaks way too easily. Worked on my truck for about a week and left me stranded. Do not buy.

Doesn’t fit well. The Orings are too large and makes it difficult to get the connector seated. The plastic is brittle and the tip of the connector breaks easily
