I knew my fuel pressure was entirey too high because of the Walbro pump, but i went and tested it anyways. Hydrocarbons were 1.83 of 0.86 allowed, and Carbon Monoxide was 77.3 of 12.4 or something allowed. h:

Went and bought a B&M Afpr, and the B&M Guage, but for some reason, i can't drop my fuel pressure below 39psi. I wanted to drop it to around 30-34 for emissions, but it's all the way screwed out, and 39psi is it.

 

oh that sucks.... i think tucson has emissions too so when i move there its gonna suck... oh well ill just keep my car registered in Sierra Vista using my friends address h:



good luck to ya though hope you pass

 

Try advancing your timing a degree or 2. And yes, the Walbro pump is probably causing you to run rich, but not because of pressure...because it flows more volume. The FPR controls pressure.

 

Throw the stock pump back in

 

stock pump went out, that's why i bought the walbro. the car is running alot better now that i have the fuel pressure at 48. i think i might just pick up a new stock pump though.
