Fuel pump switch

Heres the deal
Engine seized in my 87 GTA and the block wasnt salvagable.
I am using an old block from the 70's sometime.
Its all machined, everything is put on it.
One problem I ran into;
The switch above the oil filter (Fuel pump switch) will not fit into the block I am going to use because of the way it is casted.
Is there any way to bypass this switch?
thanks

Is it possible to tee it into the port behind the distributor, off the rear china wall?

Maybe.. Might be a pain in the *** because It isnt the same size of pipe thread that the oil pressure sender is. There would be a bunch of different fittings, I'll keep that in mind if I cant find anything else.

Anyone know how to bypass this thing?

Technically it doesn't do anything that would hurt the starting or running capabilities of the car. All the switch is, is a backup for the fuel pump relay (in the event the relay goes south, the switch powers the pump, given there is ~4psi of oil pressure).

I forget which years the switch and sender were combined into one, but you could purchase the switch and sender seperatly and get them for the correct pipe thread.

Everything will work fine mechanically. If you have the combination sender/switch (3 terminals on the switch), the gauge won't work, if you can live with that.

Just be sure there's some form of pipe end so you don't go leaking oil everywhere.

Yes I have 2 different units, one for the gauge and one for the fuel pump switch.
I did put a plug in the side of the block.
Thanks for the help.
