Is it normal to...........

Smell gas fumes in the vacuum line that plugs into the FRPS(i recently bounced off the rev limiter a couple of times) there is NO gas dripping out of the vacuum line or the FRPS and no gas smell in the oil.





Thanks Mark

FRPS?

Fuel Rail Pressure Sensor

The FRPS probably isn't bad then.

Check for gas in the oil. From what I've read, the car shouldn't run properly if the FRPS is bad.

Yeah, alot of people get scared and think they blew an FRPS just because some people have. I have bounced off the rev limiter 20 or so times and according to the perfect idling/running of my car (along with proper fuel pressure readings) the car is fine. If your car dies after you bounce off the rev limiter and/or runs like shit, then you busted an FRPS. Until then, happy rev limiter bouncing!!

Agreed. I think most FRPS failures are a result of another fuel system issue. I blew one, but that was before I knew that Ford had installed Mustang GT fuel pumps in my Cobra from the factory.

Since the replacement of the FRPS (and the pumps), I have hit the rev limiter at least a dozen times, and no issues.

its the tune commanding 80+psi fuel pressure that causes the sensor to pop.

Don't you guys have shift lights? The lights really cut down on rev limiter hittage.

I did most of my rev limiter banging on missed shifts and improper burnouts. I do it a lot less now.

I occasionally touch the limiter doing my burnouts at the track. More aware of it now though.
