Where to locate the stock water temp & pres. senders in 502MPI?

I have a twin 502 MPI set up in a fountain. I am thinking of eliminating the recirc. pump and stock thermostat housing since the boat is in FL. If I use a byppass crossover pipe with thermostat kit, where can I locate the water pressure and temperature senders that are in the old thermostat housing? Anybody ave a good idea?
Any help would be appreciated.

My water pressure gauges are tapped in to the engine block drains, port side of both blocks.

The block drain plug is changed to a reducing plug. A 45 degree pipe to 45 JIC fitting is then srewed into the reducing plug. The hose is connected to the new fitting.

Slight pain during winterization but doable. Fittings are brass and should be available at hardware stores or Home Depot. Same as ones used for propane and gas lines.

I have to do some replumbing also. In stalled new stlye sea water kits just because they were out. Now I have 30 plus PSI of water presure. From every thing I have heard that is to much.

Good luck
