Is this part really needed for OBD-1 conversion?

Just saw this part at Turner.

Didn't see any mention of it anywhere on OBD-2 to 1 conversions. Anyone with conversions needed to use this or how did they address this issue?

Thanks

You can keep the OBD-II metal pipe and not switch to the OBD-I spider hose.

No, it is not needed. You can use the metal water pipe from the obdII setup. This is only needed if you want to use the ruber spider hose. I actually just threw one of these out the other day.

It's not needed, but it would be if you wanted to use the rubber spider hose. Depends on what you want to do. I used the metal pipe that was already on the m52, personally.

My experience is If you use the metal pipe vs the spider hose the obd1 metal harness bracket under the manifold will not fit up and the obd 2 bracket is different. so you loose the nice mounting points for the connectors and the obd 1 ICV mounting point for obd1 manifold

a diy version of that adapter is to cut off the 'oring' end of the metal pipe, keep a couple of inches of pipe stub since it is slightly smaller than id of spider hose deburr it and JB weld that sucker into the housing. Make sure there is a good even coating of JB on clean mating surfaces. I left 1 oring on to help center the pipe.
seal hose/pipe with a little good stuff etc and hose clamp it. I know this works GL
