I've got a week off with no b-ball games or practice (and no school!!!!)

So i'm finally Puttin in the 5122 kit and I'm not quite sure where to put the fuel pressure safety switch....

Form brian or Ross's page (not sure which one) it says it's on the passenger side near the fuel rail, but I'm not sure exactly what i'm lookin for......dose it actually hook on to the fuel rail??

A detailed description would be great!!

Thanks for the help!!

The '97 model year has a fuel pressure test port - that's where it's supposed to go. '93-'96 don't, so I'm not sure - my best guess is to 'tee' it off the rubber loop between the fuel rails. Call the NOS tech-support though before - they are generally very helpful. I never did install my FPSS....

so you just did with out??

Is it really neccesary??

The system will work just fine with or wihtout the FPSS installed. The wires that would normally go from solenoids to FPSS should be grounded to the chassis if not using the FPSS.

I ran my systems without the FPSS.

What does it do? It cuts off nitrous flow if it detects a drop ni fuel pressure, which happens when you miss a shift, if the fuel pump fails, if the fuel filter is blocked off, if your injectors get clogged, or if you over-rev and hit the fuel cut, etc.

It is a good fail-safe system to have, but I didn't feel like tee-ing the fuel line - plus, I only missed one shift in 6 months of racing on the gas.

Chances of your motor being ruined by nitrous are (in my opinion):

40% bad install
40% leaky/malfunctioning nitrous solenoid
15% hit fuel cut while spraying
5% missed shift, hit fuel cut while over-revving.

Basic rules: check your solenoids/connections/fittings/bottle regularly, shift BEFORE redline, don't speed-shift while on nitrous unless you are really good and have good synchros.

Dan..

Isn't that the schrader (sp.?) valve you are talking about? If so, 96's do have the same port.

Sorry for going off topic, but Rdiggidy, were you on I5N outside of stockton yesterday? If yes - I was that beat up, loaded down probe that got pulled over.

Believe it or not, that was my first ticket in Cali. I've gotten 4 in nevada, and two in Ny, but untill yesterday none in cali. Wich is just dumb luck, because I break more laws, more often in cali than anywhere else.

But I ask becasue I saw a dark green MX-6 with a drive it like you stole it sticker.

Rdiggidy · 12-22-2001, 14:51

i was on I5N commin up to sac from fresno, and I do have a dark geen 6, but I don't have any stickers....

So I guess it wasn't me....

Kinda on topic I guess....the only ticket i've ever recieved was in oregon....but oh the countless tickets I deserve in calli....
