Re: 84 fuel pressure question (ben73)
One of the forum members posted a picture a month or so ago. It very well may have been elkabong. It looks like it ought to do a good job, but it was quite a "rats nest" of stainless hose and red and blue fittings. He probably has as much money wrapped up in that set up as I have in all my mods, altogether. I simply sectioned an inch or so out of the line that runs between the TBs and installed a tee fitting. I have a Shrader valve screwed into the tee. Now I can check fuel pressure at any time, just the the bigger TPI boys. That includes while making a run throught the 1/4 mile.

Its your car, but permanently mounted mechanical fuel pressure gauges in the engine bay scare the hell out of me. If it ever fails from the constant jarring of the suspension you'll have a firey mess and won't know it has failed until its too late.

Re: 84 fuel pressure question (JoBy)
thank you for the info. i might just get the hose ends and a T, and make a simple hose just to use when the air cleaner is off. i couldnt test the pressure under full load, but i wouldnt need all those angles.
