Install of fuel pressure gauge on 07 SI

Ok, What you'll need to install it.
Go out to your local autoparts store and buy a 'T' then buy 2 barbed ends that screw into it.
Fuel doesn't seem to like plumbers tape so I used locktite [blue] and don't forget the hose clamps.
Let the car sit for a min. or two so the pressure in the line goes down.
Then there are 2 quick locks on each end of the line disconect these and remove the line.
now cut the line you will notice there is a plastic liner running thru this fuel line. Now it's not that easy to shove the barbs in you really have to push hard but they'll fit. Don't forget you will be cutting out a small section of the fuel line so it's the same length. Just cut small amounts off and keep holding up to the lock connectors to make sure it fits.
And that it!
Now you know that installing a fuel pressure gauge like we have down is only for show! But later if you decide to install a fuel pressure regulator you'll be able to take adavatage of the gauge.
Took about 15 min.s to install.
Have Fun!!!!! :wavey:

 

thanks for the help ur a saint!

 

GOOD look I like it might just do it my self does fuel leak out when you pull the hose or does it just stop. IS there any bleeding i would have to do.

 

No, turn the car off and let it sit for 5 - 10 min. This should be plenty of time to let the pressure out of the fuel system. A small amount of fuel will drip out all you need is a shop rag for this.

 

What is the benefit to this mod. Aside from looking cool why do it unless unless high hp?

 

......? why do this..?

 

i understand if the car was turboed but stock car its make on sense to get it to me

 

unsafe and tacky looking. drill and tap the rail for the 1/8 npt, screw in the gauge and be done with it.

 

Is there a DIY or image of this laternative of drilling and tapping the rail?

I'm in a need to install a fuel pressure gauge right now.

 

No, turn the car off and let it sit for 5 - 10 min. This should be plenty of time to let the pressure out of the fuel system. A small amount of fuel will drip out all you need is a shop rag for this.

even better pull the fuse/relay for the fuel pump and then crank the motor to get the pressure outa the lines and then u shouldn't have any fuel in them

 

buy a fuel rail w/ the threads for a guage?

 

this is a good way to tap nitrous fuel line as well. thanks good write up

 

if you unscrew your gas cap you will also bleed all the pressure out. thats what we did when we installed the s/c.

 

nice write up

 

Drilling and taping rules apply. Look it up.
You'd have to remove the fuel rail completely to do it though. You could probably have machine shop do it just to be safe.

 

you can get a fuel rail for $100, why waste all the time tapping a keihn crap fuel rail, just get a rail and a threaded guage and be done with it..

 

Yeah, Hybrid Racing and AEM make aftermarket rails with extra ports, typically in cars which originally had return type fuel systems. I believe hybrid has a rail with a 1/8 NPT port.

 

I'm still curious as to WHY. Why is knowing the pressure of your fuel important. My only guess is that your fuel pump isn't pumping enough for a forced induction set up and the pressure is really low. Can anyone comment?

 

What's this little air filter?? With the gauge ?? Thanks

 

seems flammable
