thin

I'm currently installing my Samco hose kit, 8 pieces which I know the four larger pipes attatch to engine/radiator and two thin pipes go from radiator to overflow/catch bottle. But what are the other two thin pipes for?

We have thin gaskets and timing chain tensioners in stock and active for sale on the site now. If you plan to purchase my engine kit piston/cams/etc these items are included, meaning don't purchase separately now. These items are for club racing rules(retaining stock piston/cams), track days...
