Anyone install a lift pump presure gage? I'm thinking of adding one just for the heck of it. I've got the Edge CTS and would like to add the readout to it, but don't know if its possible. Any install help would be great. Thanks.

 

you need extra filtering for your truck. we use the gauge to tell when to change filters. since the cp3 came out in 03 we have used several different setups. most of ours are a $7.50 tapped banjo bolt from genosgarage.com a copper line oil pressure gauge installation kit from autozone for $11 and a glycerin filled 15 psi gauge from ww granger for $15 mounted down by the shifter. you should read 7-8 psi to add the readout to the cts get the banjo bolt and EDGE-98607 for $129 from genos.

 

Thanks for the reply. Looks like they have a low fuel pressure light and switch that looks good. Or I can use the banjo bolt to hook up a pressure sensor.

I installed one several years ago. They are very helpful. They allow you to monitor the temperature effect on your fuel, the health of your lift pump and the condition of your fuel filter. You should install a tee connector at the input to the high pressure pump and use a diaphram model sender that allows the use of anti-freeze in the pressure tube that goes to the gauge for fire safety.

Not sure what you mean about anti-freeze?? Looks like Edge has a new 0-50 psi sensor that can go right into a T!

 

what he talking about antifreeze is some expensive gauges come with a pos troublesome worthless isolator to keep a non dangerous substance out of the cab. the cp3 will operate between MINUS 10 psi and +20 psi, it does not need fuel for lube and cooling like the vp44. the switch and light was for the vp44 it will serve no purpose on the cp3. I did not make myself plain on the edge, to get the lp reading on the cts the 98607 is the pressure sending unit for it and the banjo bolt is needed to hook the sensor to it. the pulsations from the cp3 are not nearly as bad as the vp44 but for max sensor life use a snubber or needle valve connected to the banjo bolt and a grease gun hose between the valve or snubber and the sensor, this also removes engine vibration from the sensor. if you decide to go mechanical and want pretty you can get a pillar mount for the gauges. on a cp3 you only need to look at the gauge about once a month, not like the vp44 that needs it hourly. that is why we mount ours down by the shifter using glycerin filled gauges for pulse elimination. that $15 gauge will last longer and work better than a $300 kit. that $15 gauge will also work in the pillar mount if you want pretty.

 

Thanks for the clairification. If I can use the 98607, or 98606 and just lash it up to my CTS, that will work for me.

 

I agree with the above quote about the mechanical FP guages with the isolator (I replaced 2 gauges and 2 Isolators) then I went to a Autometer electric guage. I mounted the sender on a rubber hose as in the above quote.
I do not agree with the above quote that the CP3 does not require fuel to lubricate it. It does. On the Dodges there is a lift pump and on the Duromax's they have a 1/2 inch fuel line so the can operate without a lift pump. When my truck was new I installed a BD fuel press warning light that comes on below 5psi. I did this because of the weak lift pump on the back of the filter, after I went to the Glacier Walboro set up I left the light on and went to fuel a pressure guage.

I am running ISSPro EV2 electric analogue gauges which includes a lift pump gauge (0 - 40 psi). My fuel pressure is 20 +/- 2 psi using a Walbro GSL - 392 in line pump. At WOT with a heavy load the pressure may drop to 17 psi. The beauty of the gauge is that 20 psi is in the 12 o'clock position so in an instant I can see if I am low.

The gauges I am using are white face, black lettering, and red pointer. Nice clean gauge with green lighting which matches the Dodge lighting very well. I have the fuel filter top that is threaded with an 1/8" NPT port. I do not like digital as, is that 18 or 13 psi; requires too much time to process the information for my feeble mind. When I am towing heavy in traffic I just want a quick glance and back to traffic.

Good luck,.........dogger

 

To clarify my original post, I installed a triple gauge pillar mount. One of which is a supply pump fuel pressure gauge. It was installed prior to my factory upgrade of the lift pump from the filter to the tank. Lift pressure before the lift pump failure was 5 to 7 PSI. At failure the gauge clearly identified the failure. After the upgrade, fuel feed pressure is between 6.5 and 9 PSI. To install the gauge, I drilled and tapped the top of the banjo bolt at the CP3 to 1/8" NPT. I connected that to the diaphram fuel isolator. Then ran a gauge tube from the diaphram to the gauge on the A pillar after filling that line with antifreeze. I like the use of a mechanical gauge, but bringing fuel into the cab under pressure is an unnecessary risk and well worth avoiding.

 

I read somewhere and I believe it was on this site that pressure above 15psi would cause harm to the CP3. I also have the Walboro 392 pump and I had to cut the spring in the pressure relief valve to reduce the pressure to 14psi My gauge is the Autometer Phantom electric and it is similar to the Dodge gauges in appearance. I use a Baldwin fuel filter in the original housing and then the fuel goes to a 2 micron Cat filter and the sender for the FP gauge is between the Cat filter and the CP3 with new filters the pressure is 14psi at idle and it will drop to 11psi under full load. When the filters get older and the full load drop goes to less than 9psi I replace the filters. The previous filters lasted over 90,000 kilometers or almost 56,000 miles.
