so in my book it says my car should have 43-47psi of fuel pressure and its barely 40. its got a new filter. im having issues with it right now and i had it tuned and the guy tried giving it more and more fuel and it just kept running lean. so im thinking a pump will fix it, what are your guys opinions thank. o and pump and injectors are stock right now

 

Whats the mileage on the pump? Its stock I assume right?

 

Dumb question, but you did pull the vac line from the FPR before you measured the fuel pres? Also, are you seeing it drop under load?

 

yea i did and it would drop maybe 5 psi once u gave it more gas but wideopen it stayed around 40 and maybe would go down to 38. its a stock pump and i have no clue about mileage
