Apexi Fuel Pressure Gauge Flashing Warning Light
 

Since I have hooked this gauge up from day one, the red light keeps flashing. Anyone have any idea wats going on? Gauge reads 1kpa while driving.

Could it possibly be that it is not hooked up correctly or that it is malfunctioning? Because 1 kPa is like very close to 0 psi, so it could be warning you of no fuel pressure....

Where is the fuel pressure sensor tapped to on the fuel line? Like exact position.

my bad. Its 100Kpa that equals to 14.5 PSI.



It is hooked up to one of the fuel lines. I know that wont be a problem because the warning light has been there since I installed the gauge and at that time the sensor wasnt even hooked up.

hows ur car btw?

um 14.5psi on fuel...seems kinda low shouldnt that be around 40 specially since you are supercahrged.

Yea but where on the fuel line, thats why I asked specifically so I can see whats going on. Is it on the feed line? Return line? before or after the fmu?

My car is coming along, start it for the 1st time in one month, look at the thread on the general forum, just got a lot of stuff back ceramic coated.

sounds like you installed the sender on the return line...

either that or it's time to replace your fuel pump!!

Sounds like his guage is hooked up on the return line for sure. Almost positive your car wouldnt run on 14.5psi fuel pressure.....if so it would be so crappy.

I think we may have tapped the fuel return line. Oss, I will fix that for ya bud......

I was thinking of calling you.... btw gota show u the mounting now ;-) give me a call tomorrow sometime.
