Filters before your nos and fuel solenoids???

Im in the process of installing my first Nos kit its a cheater system. Just wondering if you guys use the filters before each solenoid fuel and nos.

No I don't currently. Have used them in past.

I have the NPT to AN fittings with the screens to catch anything big.

On the nitrous side I just use a screened inlet fitting on the solenoid.

On the fuel side I just have the big filter before the pump...I just have one big fuel system to run the motor and the nitrous system.

Thanks guys. I'm gonna use 1 before the n20 and none on the fuel.

for the fuel side I have a filter before the pump and one on the fuel solenoid its and old ford fuel filter it spins on the noid and the other side has a barb for 5 1/16 fuel hose
