Okay I was checking my engine bay out and wanted to see what my fuel pressure was so I took the vac line off caped it and it stayed at 43 now I'm on a 1g so it's 37 I believe so what I did was, was run the vac line straight from the intake manifold to the afpr because there wasnt a sucking on the vac like that goes from a Soliniod on the firewall the Soliniod has a line eunning to the intake manifold so I hooked it straight to the afpr and the fuel pressure went from 43 to 37 but when I took te line off it goes from 37 to 43 I think one that Soliniod isn't working because I didn't feel any vac and my afpr isn't set right should I set it to 37 with the vac line off and bypass the Soliniod
 
I'm not sure what you mean. When you pull the reference line off that will be your set pressure. When your car is idling it will be lower since you're pulling vacuum. What solenoid are you referring to?
 
Sorry I was at work when I posted this. It was on break and was trying to hurry. Anyways it's a 93 tsi awd stick, the 255 is correct and it's on stock injectors, that's how I bought the car. Te previous owner installed that pump and te aeromotive 255. I'm having a long start time when turning the car on and say alot of people had that problem when they installed an afpr. The way the vac Lines are set up is a line from te intake manifold to something on the firewall driver side and then from that to the regulator. There is no vaccumn at all from the hose that goes to the regulator but there is on the hose from the intake manifold. Can I bypass what it is hooked up to? And when I take the hose off the afpr is does not change the pressure and it's at the 2g stock fuel pressure. Now when I put the hose directly from the intake manifold it drops the pressure to about 37 the 1g stock pressure. My question is should I bypass this thing on the fire wall? Which I was told was a fuel pressure Solinoid.
 
Okay but should there's no vac. Running to the fpr. It goes from the IM to some black box and from there to the fpr. Should I bypass this someone told me its a Solinoid and they bypass it but it might throw a cel

You can bypass the solenoid and run straight from the manifold to the fpr. Leave the electrical connector plugged in to the solenoid and loop a piece of vac line on the two ports and you shouldn't get a cel
