Hello all, I'm ready to install my electric FP gauge. I'm running it out of the banjo bolt on the cp3, through an 18" tube then into the sensor mounted at the brake booster. I need to know if I need to prime the line, or will it prime itself. If so, how do I do that seeing that the sender is sealed. Thanks

 

I'm a little confused. Why do you need to run fuel to a sender on an electronic gauge? You should just screw in the sensor and the rest is wires isn't it?

What kinda gauge is it?

 

I just put an electric gauge in this last weekend (along with a fass fuel pump). The instructions say to bleen the air out of the line to get a more stable reading. I loosened the gauge sending unit from the hose and the bumped the starter (do not start it just a bump) whrn fuel started to leak out I tightened the sending unit. Gauge works great.

good luck

It's a dipricol electronic fp gauge. It basically has a 3/8" npt nipple on the end and a 3wire connector on the top. Manufacturer says not tomount it directly onto the engine (vibration). so I'm running an 18" long hose from the tapped banjo bolt to the sending unit. I would think that air would compress and the reading wouldn't be as acccurate. I'm going to try getting as much fuel in the line as i can by loosening up the sender, then tightening it when fuel comes out as mustang suggested. Thanks

 

Wow they must really build their sensors cheap if they cant handle being mounted on the engine. Try to get as much air out of there, if there is room, I would put a shrader valve in the sensor line higher then the sensor so you can bleed the air out. With the way it sound like you got it mounted the sensor will be the highest point in the system so if you were to run it out of fuel you'd have to bleed it again. Just a thought.

 

That IS kinda weird. I just screwed mine right into the fuel filter housing, however mine is an Autometer.



I'd double check with your gauge company to see if you can mount it like this.

 

Mayfair, It can be mounted like that if I got an aluminum billet cap for the fuel filter, but it would read pre-filter. I wish I could do it that way, but dodge redesigned the fuel filter housing in '03 (i think). Now it's plastic and has no top bolt to mount to. The extension tube idea was right from geno's garage, but autometer noted that the sender must not be attached directly to the block either. Anywho, I got it in today and it seems pretty good so far, I just put a tee reight below the sender and use the plug as a drain valve to fill the line.

 

Cool - Glad to hear it all worked out. What IS your fuel pressure now?

 

Sorry forwaiting solong to reply. I had to wire everything in. Finally got everything in and working. My FP sits around 9psi, drops to maybe 6 at WOT. Boost has gotten up to ~30lbs, and Temp (post turbo) highest i've seen around 700 degrees. Thanks to all that helped me with my install questions.

 

Is it me, or does his psi look low & his boost look high? Your EGT's are probably about right though.
