is this an aftermarket pressure regulator? only those can be adjusted. if you smell fuel then you have a fuel leak. make sure all your fuel lines are tight and check to see if the area around your injectors is dry. you usually burn too much fuel when the o2 sensor is getting a false reading, that will happen do too a faulty o2 sensor, no cat (resistance in the exhaust stream), or an exhaust leak.

you should have around 45lbs at idle and around 50-55 at start up. under load your pressure will rise with rpms.

 

yes its aftermarket, i didnt htink to check the O2 sensor, and the area around the injectors is dry. thanks for the info. Wouldnt there a code showing for th o2 sensor being bad?.. just asking.

 

sry it would be 35lbs at idle. not 50. if it's aftermarket it will be set at 43lbs out of the box. there is an adjustment valve on it to adjust pressure up or down. it will change the amount of vacuum the regulator sees. remember though if you adjust it your changing pressure under any % of load.

 

thanks for the info, but the FPR was bad, just threw a stock one back on it
