Im swapping a guy for his 97 civic with lots of work done on the engine. The main problem is that he bought an AEM fuel rail and aftermarket pump, and the pressure hasnt been set. Is there a relatively quick and easy way to do this without tuning the ECU?

 

Rail and regulator or rail and stock regulator?

There's no point increasing the pump size if you don't also have a fuel pressure regulator and/or a turbo. I don't believe any bolt on's require (or benefit from) changing the pump or injectors.

AEM fuel rails are a cosmetic change that don't affect performance at all.

An easy way to set the pressure's to jumper on the fuel pump so it's always running, then adjust the regulator till the pressure's correct. If you don't have an adjustable regulator or gauge, don't put on the larger pump.

 

I dont know about the reg, but it does have a bigger pump. Im assuming these come with default settings? The guy built the car and had a heart attack and a stroke, so now he's selling it to me, but its a little unfinished, and Im not entirely sure of all the work hes done to it.
