My Buddy is runnin' an H22 and a custom turbo kit in his Del Sol. He's only getting 10 psi of fuel. Should be around 40??? is that correct? He has an in-tank pump, one under the hood and a fuel pressure reg and 440CC RC injectors. His car has variable stutters at different gears and RMP he wants to know what to look for in his fuel system to fix the problem. He tries to start it but it dies and feels like its not getting enough fuel. There's spark, enough air and the spark plugs are getting fuel???? thanks.

 

where is his fuel gauge, also what regulators is he using? maybe on of his pumps are not working?

 

no Fuel Gauge, which is a bad mistake. My Buddy's Dad shop has it right now and they tested it at 10 psi. Don't know the FPR but havne't tested the pumps either.

 

my guess is maybe one pumps works and the other does not.

 

thanks alot i'll let him know

 

Check to make sure the inline pump is not hooked up backwards or that the polarity is reversed and make sure the fuel regulator isn't busted.
