fuel pressure guage

[Bob Cook]

I have one for a "P"

I have personal concerns having FUEL running in and out of the cockpit.

I replaced mine with a Shaddin for this reason including improved accuracy.

send me an email if interesed.

Bob,

Welcome back. Be advised, private email does not always work well on the board. If you want someone to be able to email you, you may wish to provide an email address in your message. You can spam mask the address if you want, by telling folks to replace "zerk" (or any word you like) with an at sign, like this:

webmasterzerk337skymaster.com

translates to

webmaster@337skymaster.com

both if you replaced your factory fuel flow meter, how did you set the limits to show up on the shadden (red line, green area ?)
i have a shadden; but it does not show the limits. i'm i doing somethin wrong!

Hi Kevin..... congrats....

The fuel flow should be calibrated via factory proceedures which should give you 36-37 inches of manifold pressure along with 24 gph fuel flow. fuel flow is critical for determining proper operation during take off (100% power). We calibrated the Shadden during the continental setup proceedure.

For setting mixture you can use known fuel flow for given power settings. I happen to use the EI engine monitor to set cruise fuel flow / as in degrees ROP.

Somewhere in the Continental engine documentation is the fuel flow for given power settings. Believe this was extrapolated from the charts in the back of the operating manual.

If you are operating a "P" then you should be running full rich on climb and take advantage of "fuel cooling" which again relies on the factory calibration proceedure.

Fuel flow dictates power.


Hope this helps

what i'm asking is = if you remove the orginal fuel flow guage, and only have the shadden system how do you tell if you are in the green red, ect except to memorize each fuel flow setting (so may gph for redline, so many gph (between this and that) for green spectrium.
