Help with splicing radiator hose
I have been to the rx7turboturob.com site and it said that I can splice a hose and get a T connector for my sending unit for the electric autometer water gauage. I understand the concept, but I need a few pointers. I have searched and could not find anything for 3rd gen.
The only hose that I can see that may work is the small 3/4 Inch(?) hose near where the coolant cap is.
when I attach the sending unit to the T connector, it seems like the sending unit would partially block the flow of water. I know this must sound like a really stupid question, but I hope someone understands my questions. Any links will be helpful.
Thanks for your help!

Never heard of splicing the rad hose. I don't think it's a good idea... Rob's site says punching a hole in the thermo housing, not splicing the hose. Where do you hear about this splicing the hose idea? Your idea?

If there is a better site that can detail this more. For example....he said you can buy a T connector and splice the hose....I would like some details on what is the right hose to splice, etc. He showed where you can drill into the housing I can see the spot, but how do i perminantly attach the sending unit to it? It cannot screw onto the area that I would have drilled out.
Thank you all for the help. Forgive the spelling....
Rotor on!

By splicing into a rad hose you are going to have inaccurate readings. The reason they place the sender on the thermo housing is that will give you the most accurate readings, as coolant comes out fo the motor headed for the radiator. If memory serves, I believe you use a 1/4" NPT to tap into the housing, then you thread in the sender. That's for the mech gauge. If you have the electrical, you may need a smaller tap, the instructions should say. All in all it took maybe two hours to do it, including bringing the housing to a machine shop and letting them tap it (DO NOT try to tap an NPT fitting into aluminum unless you know what you are doing).

The instructions don't say crap about it. Its an autometer and it shows a diagram that says Hook up the sending unit, then the ground and power. Thats it. Its electrical.
I'm just going to splice the hose and be done with it, this is too much of a PIA.
Thanks!
