What size T fitting will I need to tap the block on a 97 EX in both inches and -an for my feed line. Shouldn't a plumbing store carry that. Also, won't I need a female coupler to fit on one side of the T in order for my factory oil linr to hook back up to.

 

start by reading the new user faq at the top of this forum. basically you need a bspt threaded (hard to find) fitting to stick in the oil sender and from there you can tee into standard npt fittings. -4an is the standard but you might run smaller or restrict the oil somehow.
again, just read as there are a lot more details you need to know. good luck.

 

1/8 bspt on block and -4 an ss braided line for the hose.

 

heres a diagram i made hope it helps!
