In the feed line between filter and rail is where I'd put it.
Or if you have an aftermarket FPR, put it on the top in place of the mechanical gauge that usually goes there. I'm assuming the sensor is 1/4" NPT and will go right on the FPR. Much easier than splicing in a 1/4" NPT bung.

Nice , will go with the fpr route. Will definetely simplify things and save a little cash also.

Small update.

New walboro 450 e85 pump with the new high pressure release
new aem digital fuel pressure gauge
new diaphragm for my aeromotive fpr

Arrived yesterday. Hope to gets some work done this weekend

[SlowWhite]

So I installed the new walboro 450 on sunday. And car still wont start or get fuel pressure (regulator is reading 0)

I am at a complete loss. I have an aem fuel pressure gauge which I havent installed yet. As well as a new diaphragm for my apr that I havent installed. (Didnt want to change to much at once)

I unplugged the fuel line and no fuel comes out. I've checked the wiring with my multimeter. I get power all the way to the connector inside the tank that attaches to the pump itself(however i have not tried the other end of that connector as i dont want to open up the wires etc). But the pump doesnt turn on when i power it up via link.

Any ideas on what's else? Only other thing I notice is 3 of my 4 aem gauges dont stay on while cranking where as they used to, and every time the car ever cranked and fired up those gauges stayed on.

If you unhooked the main fuel feed line and you aren't getting fuel, that's problem #1. I don't remember if the DSM ECU provides a trigger for the fuel pump, or actual power, but it's possible your ECU crapped out.
I remember my fuel pump signal went bad from the ECU so I had to hardwire it to the battery using ignition as a relay to turn it on. The downside of this is if you get in a crash and don't turn off the key, the fuel pump stays on, which is a safety concern. Normally if the motor shuts off unexpectedly, the ECU will also cut the fuel pump signal so you don't burn up in a gas fire.

When you say you have checked power, do you mean the plug at the top of the tank? I also had a problem on my 2g with the wires going bad so I had to replace the plug. It was intermittent and very hard to diagnose. One day it would work, and another day it wouldn't, and I had to ride in AJ's and Peter's cars on a cruise because of it.

Finally figured it out. While testing the pump while hooked up like normal, only the pump was outside the fuel tank I accidentally bumped the fuel pump hanger against the back seat floor and it turned the pump on real quick. So I tried to reenact it and it happened again. Started to giggle wires and sure enough the positive wire that is inside the "white" connector that connects the plugs from the outside of the tank to the wires inside the tank is loose.

Depending on how far I move the wire the faster or slower the pump runs. The car fires right up when I fold the wires to create contact.

So looks like a new fuel pump hanger in order.

Well new fuel pump hangar, along with the new Walboro 450 with the high pressure relief installed last night and test drove today.
Fpr at idle went from 42.5 to 60psi. So I have to adjust that once I do a boost leak check.

I also still need to install the new arm fuel pressure gauge. Only thing stopping me is I'm not sure where I'm going to get power from. My poor fuse box under the dash looks like it's just full of wires now.
Wish someone would come up with a power source/bar or something for these cars that you can just plug all your gauges and accessories into one spot.

I still have to tackle the last oil leak from when that lady ran me off the road, but that will be after taxes next year. As I'm going to get moroso oil pan, an oil cooler installed at the same time.

Looking good man, sounds like it's almost sorted out!

Fingers crossed.

Wife actually sent me pictures today as a surprise while I've been at work she washed and waxed the car and her and my son also detailed the interior as well

Had been parked in the garage for last few months so was definitely in need of a good cleaning.

[SlowWhite]

Got the fuel pressure gauge installed today.

I also took the car to work yesterday. Had a guy a work who drives a 03 v8 mustang with exhaust and intake talk crap all night to me. So on the way home him and I did 2 pulls. And not like it's anything special but was my first race in a long time. And I put bus lengths on him, was seeing 54lbs/min. With just the tune from my hx35. (9.7:1 a/f) tune needs to be reworked lol

Just a picture update.
