nope, no spot for tap 
but boe, your right...it actually fit perfectly...but i had to cut the top of the stock FPR with a dremel,...sand it down, swap pressure spring... and and bolt it up...very easy actually..part # for the FPR-Command-Flo 46056 (mitsu turbo fpr)...part # for gauge- 46054
as far as putting a tee...putting it on the high pressure side, hmm..how would i go about doin that? (what fitting would be best ?)
sorry for horrible pics (camera phone) and long post...
oh btw..nice oz's you guys..

advantage is being able to control fuel pressure coming in. hence the pressure gauge and air/fuel meter. i paid about 135 for fpr and gauge. not so bad i think

Be carefull when playing with the pressure. The car doesn't like to be played with too much... i did that back in my early days to lean it out a little when accelerating. If the piggy was around i'd have gotten that but the fpr can be used like this.
I didn't see till now that it was a capping type regulator. Is the regulator a rising rate setup?
Some info from my early days... i found taking pressure to around 28psi made the car run fine and when you got on it gave it an AFR of around 12.2-12.5:1 instead of 10-11:1. This made a huge difference in my pulls. Gave me about 10-15 hp in the mid range and about 3-5 peak.

nah, its not a rising rate...unfortunetly...but i will take your advice for it....i guess that is why i am so concerned with the correct installation of this psi gauge..so that way i can accurately monitor the fuel pressure...along with my a/f ratio meter
thanks again for the tips boe...that should definitley help me out when configuring the ratio i wanna achieve
10-15 hp in the mid range and about 3-5 peak. <--sounds good to me

What good does the gauge do if it's not on the high pressure side? I can't see the pics clearly so I'm not really getting where you're getting the reading from. I just cut my fuel line. I'll replace it with braided SS hose when I get a little scratch again.
EDIT: btw, slightly off topic, but what's normal idle fuel pressure on a stock lancer?
