1 or 2 FASS systems with Twin CP3's

[JoshWelsh]

With twin cp3's would 2 fass 95's systems work as good or better than a single Fass 200? Does it make sense to run another fass 95 when you already have fass 95 on your truck?

I cannot speak for twin cp3s, but with my super cp3. 4 , it will pull my normal 45psi FASS 200 down to 38 to 35 psi when under moderate/ heavy throttle. I do run the 1/2 inch big fuel line with 8AN fittings. I would think a single fass 200 would be just fine.

most people only run one pump to feed dual cp3's. too much fuel pressure has thrown error codes on some that have tried raising pressure to accomodate the two pumps. With the cp3's working together the demand is actually taken off of the lift pump.

2 pumps that are set up for 95GPH are still only going to push 95GPH. It will have less pressure drop with the two pumps, but still only move 95 gallons.



Dual CP3s will only flow a little over 100gph maxed out, by themselves. The fuel lines and injectors cannot flow enough to utilize the dual CP3s to there full potential anyway, so GPH rate is not as important as just keeping the pressure up. A single 95gph @ 45psi will handle it, and if you want some security a 200 will definatley get it done.

Two pumps pumping 95gph is 190gph.

Two pumps pumping 45psi is 45psi.

For the pumps to pump 95 gph each they need seperate feed lines or one feed line that is T'd before the pumps and T'd back after.

If you have one pump plugged into the next then yes you would only get 95gph.



If you have the FASS 95/150, then you could upgrade to the 150gph gear if needed. I have the parts to upgrade a FASS 95/150 to the FASS 150/150 if you are interested, though I'm not 100% sure the pump motor you have can handle 150gph and 45psi, I'd have to look into it.
