AFPR Question?

[TKI]

Guys, I dont fully understand how to use an afpr. I know the concept, but people's say-so has kinda confused me.

Ok, what will I need to set the base fuel pressure at?

Will I need to adjust it any more afterwards?

If so, then how much psi.

Right now, I have a '90 GST with K&N, walbro 255, and removed vacuum lines.

I know these are kinda newb questions, but Im still new to the 4g63. I just havent had any hands on experience with some things, and I dont want to mess things up.

Also, I was thinking about buying the FTP FPR from Import Evol. Is that a good one? I mean, as being user friendly.

I just need help understanding the basics of this better. Ive looked around (searched) but I just cant seem to fully understand it from what Ive read.

Thanks for being patient with me!!

Stock 1g fuel pressure should be set at 37psi with the vacuum hose off.

You mean just disconnecting the vacuum line on the top of the fpr? Also, I assume thats with the car running, correct?

You must set the pressure with the car running unless you know how to energize the fuel pump using the jumper type wire near the battery. Once you have the fp set correctly then reconnect the vacuum.
