Hey guys,
I am about to start test fitting my intercooler to see where it will be centered, but I needed your guys help identifying 2 lines.
There are two hard metal pipes that come out of the engine bay and go around in front of the radiator. From the looks of it these lines may get in the way of my IC and IC piping, but I want to know what these hardlines are and If I can remove them.
The pics aren't mine, I found them on PO looking for a diagram of the front bumper. BTW on a similar subject, is it possible for me to remove and reinstall the bumper all by myself? I heard it takes 2 people, but just in case I cant find somebody to help I may end up doing it myself.
thanks

It's the ps cooler. It can be moved. The procedure is shown in my old f-max install article.

Do the PS lines act sort of like a radiator or intercooler for the PS system?
also on a different subject, I want to tap an oil temperature and oil return fitting into my oil pan. What are the name of the fittings that I'll need to get these to fit? also what would you recommend I get for the rest of the oil drain lines?
I saw your post on PO.com where you provided me with the part numbers for the oil send (thanks).
For the drain line. I'm not going to hunt down the part numbers, you can find them yourself from anplumbing.com or summitracing.com if you do a bit of research.
You need to decide what size of return line you want. I think -10 is adequate, but if you really want you can go to -12 size line.
Fittings you'll need from top down:
- You'll need an oil drain flange. Mine comes with a 1/2" female NPT fitting, but this one from roadraceengineering.com says it has a 5/8" female NPT. You'll have to check what the size is on the one you order.

- You'll need an NPT to AN fitting to go from the drain flange.
- THen an Auto-Fit hose end fitting with the right AN size
- A length of hose in the correct size.
- Another Auto-fit hose end
- an AN weld fitting to attach to the oil pan
The oil send parts I suggested already have the ends on the hose, it doesn't need an extra work. These, will need to have the hose ends fitted onto the hose after the hose has been cut to length. It can be kinda tricky.
Here's the fittings I'm using from the turbo side. The return flange is on the bottom.

Even though it's not screwed tight together, you can see how long all the fittings get. In order to shorten it up because my turbo sits pretty low, I'm getting the drain flange ground down and the threads cut off the NPT to AN adapter and having the two welded together.
The welded fitting on the oil pan will look like this:

This is not the place you should put the oil return fitting on the pan. It should be high on the pan so it's above the oil line. The shop that welded this one on didn't listen to me and ended up welding another one on higher up.
The hose end that goes into the pan, you might want to get a 45 degree bend like I did. There's not alot of room down there and it makes it easier.
EDIT: This gay webforum keeps putting smilies in my url and I can't stop it, so you'll just have to go to the galleries the urls point to and find the images I'm refering to.

Thanks DirtyLude, I'll do some searching around on those two sites and locate those parts. I just wanted to make sure that I didn't leave any parts put when I do the install.
