gostlrs..
 by chance did any of the other cars have a solinoid on the firewall between the fuel pressure reg, and the manifold.. like a capri does???
or should i say like a b6t does....

  listen,, if you push boost to a stock fpr. it will pop the inners and leak at the top arround the hat... trust me... we poped 3 FPRs on the festiva build, before we figured out it wasnt a honda, and you cant run the FPR to the mani without going through the solinoid on the firewall.
the valve closes under boost and is why you cant run your guage there.... if you splice in before the solinoid it may work....
 
but im tryin to tell you from experience... leave that, and the vacumme line going to the distributor, alone... theese both controll things that are vital to the car running properly and not blowing up, under higher boost pressures....

theese cars are older than dirt. and everything is vacumme controlled manualy.. old school....
nothing like the jdm monsters youve had... the technology in a jdm motor is more advanced...
 things like timing are computer controlled on those cars and the turbo cars in japan have fprs made to see boost... some are even rising rate and boost relative....
 but thats another rant....now aint it...

the truth will be told when joshua trys to the car on the street...
 if hes back on here in a few days saying the needle will go to zero but not above it  its becuase it was tapped after the solinoid on the firewall ...
 yall are a riot... just try it till it works right....LOL

The solenoid only closes during a warm start. Its there to prevent fuel boil off in the fuel rail when the computer senses an engine start while the engine is warm. This raises the rail pressure and allows it to fill the rail with cold fuel faster so you dont end up injecting vapor and giving problematic warm/hot starts.

That being said, I've always run my boost gauge to its own dedicated nipple.

For the past year I've been running a vac line straight from the manifold to the FPR. It has not failed on me. They are meant to see boost because they raise fuel pressure as the boost raises. Were you running a Walbro pump on your Festiva? Exceeding their flowrate is a good way to kill them, they're not meant for a high flow fuel system.

10-4.. we run walbro on all of the turbo cars we've built, and that makes alot of sense.... so thats why when a guage is run from there its messed up till the car heats up  thanks
for the clarification

now, would you agree with me to leave the fuel and timing related vac lines alone and use another bung or nipple specifically for boost guage???

hey gost, thats the one i used...

and on the other side thares a nipple thats got a 90* bend to it.. it generally goes to the overboost sensor but if you grab the nipple you can twist it arround so it faces forward and thats where i run the bov from....

I try to run my gauges and extra stuff from their own nipples so as not to affect anything else.

ok the tube that came with my boost gauge is bery thin so to get it to fit on the nipple i will have to cap the T connector so i have the tube and then the hose that fits, will that work ?

P.S can i get some pictures of how your guys gauges are set up in the engine bay.

ok i noticed that my boost gauge is not reading the same as the stock one. when my stock boost gauge starts to move my boost gauge is already at 5 psi

stock gauge has to get signal then move if that makes sense? the aftermarket one is reading real time and not converting anything.

when i used the autometer gauges what i do is put some silicone about 1 inch around the part that hooks up on the gauge. then cut off the plastic part about 3 inches down. slide over the vacuum hose i want to use and zip-tie it at the gauge. when i would put some more silicone from the lip tie to the fitting and never got a leak. that plastic hose is crap

They both read close enough to real time. One is more accurate than the other.

I slipped the telfon gauge line inside of a normal vacuum line and then sealed it with electrical tape. Ghetto, yes, but its worked for a very long time... you could probably use clamps or as said above a ziptie or something. You could also find the proper brass compression fitting with a vacuum barb on the other side for a 'proper' connection
