Temp question

i got the gauge for the temp but it reads form 100 to 250 is that good

That'd be fine... It just wont register anything until you get close to operating temp, which won't take too long... and if you want it to read anything higher than 250 than you are going to have major issues far beyond your temp gauge!! LOL... So yeah I would say that should be a fine temp gauge, so long as you dont mind waiting a little bit until you get any indication on the gauge..

now my other question is i got the sunpro and it say it machanical it has a wire that looks like a spring is that good or do i get the electrical one plzz help

That is a capillary tube. Do not cut it. You can unwind it to fit your space. Cut it and you buy a new gauge.

is that capillary tube good or the wire ones better

Cap tube is better. But make sure you protect it where it comes in contact with anything

does that tube have water in it

Oil I think
