I have a non-adjustable fuel press. reg. on my swift that is permanently attached to the fuel rail. My car runs lean, so I am going out to buy an AEM universal fuel press. reg. to install inline with my stock regulator and rail.
I was going to install it in the return line to the tank, after the stock rail/regulator.
Will this help with my lean condition?
And, is this proper install? Is it okay to leave the stock regulator on and functioning? I've heard different opinions on this one...
Also, the AEM unit runs about 170, and I would have to find AN 6 nipples for it to hook up my fuel lines to. Anyone know of a cheaper, but still adequate unit (preferably one here in the U.S.)
Thanks
