Need another opinion

When running twin cp3 pumps should I run a lift pump to each cp3. Or is one air dog sufficient. I was gonna run a 150 to one pump and a 95 to the other since I had both laying around?

 

[Dan@PPE]

Are the pressures on each pump regulated?

On the cp3s yes. One lift pump is a air dog150 and the other a fass 95

I doubt either pump by itself will hold positive pressure if you use the CP3s to their full potential. If you do run both pumps, I would recommend putting a Tee between the feed hoses going to each CP3.

Yes I had planned on it just to help equalize and difference. One cp3 is modded the other is stock

Since you have both laying around I would run them, but put a T and maybe have the second one on a switch if you can remember it. Or sell them and get a 165 or 200

airdog 165 wont be enough i dont trust diesel shops anymore

What's the reason for the switch

 

[adeso]

Just so you are not alway running 2 pumps when you only need it for max effort, guess it doesn't really matter

Got ya makes sense. That's all I need is another switch in the truck

 

[dracing70]

What do u guys think about two pumps sucking through one 1/2 in. Draw straw. Too much?? Or will I have to run a suction hose for each pump?

 

[LWATSON]

Would the stronger pump push fuel back at the weaker pump when plumed together?

 

[mill1901]

As long as both lift pumps are regulated to the same pressure, there should be no problems.

 

[dracing70]

So one suction line will supply enough volume for two lift pumps and two cp3s? Or should I utilize the draw straw with one lift pump and the stock suction with the other

sump the tank

 

[TNRGreene]

I have mine drawing from the stock pickup & a sump. Just the way it is after all the mods & I left it. The sump alone would be sufficent as NJ says above.

The Fass 150 will be enough for your needs. If you run out of fuel add the other one and tee like was said above. I ran 2 95/150's last year with one off the sump and one off the top tee'd at the front. You could also tee it at the pump and run 1/2" line to each pump which will give you an abundance of fuel. Nothing wrong with running 2 pumps but if one will do it why bother.

Ok thanks for all the info. Makes sense. I just figured I would run two since I have them
