Is there another location on the block on my 351M to plug in a oil pressure switch? I got a cut off switch for my electric fuel pump and was wondering if there was another location other then the oil sending unit for the gage, reason I ask is the sending unit is in a tough spot being in the back. Thanks

 

There should be a tap between the oil filter and fuel pump (with that gone, you'll have more room). The photo below is from Bubba's page. Note that these pipe plugs can be pretty hard to get out after 30+ years without rounding out the hex. You might have to make do with a T-fitting in the back. That's what I had to do on my straight six when I did the conversion.

 

We'll it seems I got lucky the plug came out pretty easily. Thanks fmc400 for giving me the idea on your electric fuel pump conversion trend, that safely switch sure works good and makes it much more safe.

 

Glad to hear.
