This makes me really happy.
No more rubber hose pushed over the barb with non efi clamps holding it on.

Pump install kit came today, might make some noise this weekend.
Late night tinkering in the garage.
I just came inside from doing the same.
Ok dude what’s the chubby chebby in the garage? Looks cool.
53 sedan, my roommates with a inline 6.
Nice. Those rides don’t always get the love they deserve. Neat cars.
After a few issues the truck is running has 20 gallons of 91 and under heavy load the fuel psi drops to 56 at idle its 59.
It rips, much more power then before. Thanks @folkenheath for setting me up with the correct fuel system.

Next on this list is lean out the cruise, then plumb the trans into radiator then to the cooler. I either need a new radiator or get mine cleaned.
So you have a trans oil temp guage now ?
Be curious to know what past trans temps in Phoenix summer w/o rad cooler compared to with.

Have had one for years, the trans hangs around 205 in the heat. I would like to get it lower.
Put about 55 miles on it today, ran flawless.
No problem. Happy to help. Good job on the sending unit.
Now that you have the right system, hook up the manifold reference hose so it's not 59 at idle.
Also, I remember you running large injectors, that were way overkill? I would run them at 43 psi if so, not 58. Then at idle with the manifod reference they will drop to maybe ~35 depending on your engine vacuum, and still go back to 43 at full load.
Just remember to change your set fuel pressure in the Holley parameters to 43 and not 58. Even if your injectors are rated at 58, some are rated at 43 and some at 58, make sure you have those 3 input correctly, the flow rating and flow pressure, and the set pressure.
This should give you better resolution and fuel control at idle by just hooking up the vacuum hose to the regulator and lowering your fuel pressure.
BTW, where did you find the install kit in stock?
Not sure on the part number but they are GM 50lb injectors, I could find them if you want. I'm a little confused on the manifold reference signal and don't fully understand how it works, I thought the engine required 58 psi at all times?
The install kit came from amazon, I went through tons of pages until I found one that looked like the correct one and bought it
Found a shop that will clean my radiator, they said about $220 to disassemble it and flush the trans cooler. I was looking for another 4 core radiator to replace it that's brass and copper. It is closer to $600!
You just a hook a vacuum line from the intake manifold to the regulator vacuum port. Then it will drop the fuel pressure based on engine intake vacuum. It lowers the fuel pressure at low load and leaves it high at high load.
Make it easier for the computer to compensate. I run all of my stuff like that. It basically makes the differential pressure between the fuel rail and intake manifold side of the injector always the same no matter the condition. If you have 58 psi of fuel pressure and the intake is at 7 psi of vacuum, then the injector sees 65 psi fuel pressure. The vacuum referenced regulator equalizes that.

That is pretty awesome, I will have to hook it up. So at what psi do I set the regulator at?
I'd set the regulator for 43 psi, without the engine running (or the vacuum line unhooked).
Then hook it back up.
Don't forget to change the set fuel pressure in your Holley parameters after you readjust the regulator.

Silly question, but would this make the engine use less gas?
That's about right. You have a copper/brass set up now, correct? Are they going to take the tank off and rod it out or what?
