I double checked with Rob today because $400 sounded a little high when I read it. He told me the following:

If you gave him the intake manifold and he supplied the fuel rails, and bungs, it would cost $425 total.

If he could use your fuel rails, but needed to use his bungs, the price would drop to $325.

If he could use both your fuel rails and bungs, the labor price to install them would be $245.

The reason for not knowing if he could use your fuel rails and bungs without first seeing them is because the tooling he has might not be the correct size.

Trust me, Rob would use your parts, as long as he could do the job correctly with them and they weren't going to cause him too many problems.

I know $245 might sound a little high to put the intake together, but believe me, it does take some time to make sure everything is lined up correctly so there are no leaks as well as making sure the job looks good when it is completed.
