Default air pump check valve

A friend asked me to ask the following...

Theair pump check valve (Ford: E9VE-9A487-AB) that attached to the pipe leading to the heads broke off the pipe at the nut on his 93 Mustang GT.

When he attempted to remove the nut off the pipe, hebent/crimped the pipe between the elbow of the pipe and the threads where the nut from the air pump check valve would attach; the bend/crimp is closer to the threads than to the elbow and having cut the pipe toward the elbow, henow can see the bend/crimp has only reduced the "ID" of the pipe by 20%.

Hesuccessfully removed the old nut from the threaded end of the pipe and attached a new air pump check valve to the old end of the pipe. His plan is to now re-attach the end of the pipe to the rest of the pipe with a high-temperature hose and hose clamps.

All things considered, is this a stupid idea or should he simply replace the pipe?

Replacing the pipe seems to be a pain in the butt since there is not a lot of space to remove the bolt holding the pipe to the block nearest the valve; although the other bolt seems to be more accessible. (If he has to replace the pipe, are there any tricks to removing the two bolts that attach the pipe to the block?)

Any thoughts or suggestions would be greatly appreciated.

Thanks!
