I recently purchased and installed pre-bent cooler lines from Inline tube. They look great and seem like a quality product. Here is the issue though, I can't figure out how they should be run. I have them installed now, but they are tight up against the headers and that cannot be correct.

Does anyone have pictures or diagrams of how these lines should be routed around the chassis, engine mounts, exhaust etc?

I have an 83 K5 and 87 R10 with 700r4's.
I have stock exhaust manifolds so it may be a little different than your headers.

I can take a pic.

I just did my 87 r10. Lines take a hard down turn from cooler, jog to the left, and hard close to the bottom right side of 700r4 in clips on pan bolts. I have stock exaust as well. Where are they hitting the headers?

Here is how my lines are routed. It was hard to capture in one photo, so I took it in stages. Picture 4 has where I am in contact with the headers.

Just checked mine, the routing is close but mine go under the motor mount. I have stock manifolds.

Thanks for the pictures. Looks like you have a 2wd though. Not sure if that affects the routing.

My 75 K20 lines route like Rory has his, gets them away from the exhaust and that's the way mine was from the factory.

Wow, didn't realize how ugly everything is getting under there now that she's just a driveway ornament...
