N and H:

Is the 3rd pic of the broken return line? Either way, yes you can run rubber fuel line all the way back.

1st pic, someone repaired that section; those are the type of EFI hose clamps I was referring to ..)

to address your question about how much is too much money into a project, here's my two cents. I have a 89 Bronco ii, I got it from a junkyard and have put many thousands of dollars and man hours into it over the past 4 years. Although I will never get back what I spent on it if I choose to sell it. The experience of building a truck and learning how to really wrench on a engine is priceless. Even if you decide at somepoint that its more hassle than its worth I promise you you'll get some good memories with your kid as you go. I really hate my truck sometimes, especially when it gets a ride on a flatbed but to me its worth every penny.

So this little device sitting on top of the engine has a fuel line coming out and going back through the reservoir and back to the tank. Those two hose clamps don’t appear to be standard issue. Can I lose that whole setup and just run a regular fuel line back to the reservoir? My hose is broken.

That hose goes to something else. If it was part of the fuel system you would have fuel going everywhere.

You can't get rid of that setup. One line is supply, the other is return. The return comes from that round can mounted in the back with the vacuum line going to it. That round can is the fuel pressure regulator. It keeps the pressure even going to all the injectors.

That broken line WAS fuel... and it did go mostly everywhere and a little into my bucket. LOL!! So now it seems my fuel system is buttoning up. Still not starting. How do I test the pressure regulator? Then there is a grey manifold looking device for the fuel injectors. I have to take off the intake manifold to get to that and the injectors? I am guessing the injectors are plugged with bad fuel too. Can I clean those or do I HAVE to replace them?

See that black plastic cap in the picture below? That is your fuel pressure test port. It is basically a tire valve in the fuel manifold. You can buy a pressure gauge that plugs into it and then test the pressure. I am cheap and don't have one. I poke the valve to relieve any pressure, and then I unscrew the guts out of the valve just like you would with a tire using a valve removal tool. I then slip a rubber hose over the port with the guts out of it, and put a hose clamp on it. Then hook the other end to a regular pressure gauge. I usually use a long hose and tape it to the windshield for a road test. But you don't need that if it won't even run.

Removed the upper intake manifold on the way to injector removal. We appear to have fuel through the rail so this should be the last option for fuel stoppage. What is best practice for this project (cleaning intake manifold, sensors and injectors)?

Best way to clean injectors is to toss a set of rebuilt and flow checked ones in.

Injectors are a very precise component. 30 years of ethanol varnish and intake soot do not improve their performance. Consider a set of Bosch 4 hole injectors if available, they tend to function a little better. My idle quality greatly improved with them.






Other than that, look into a catch can for your pcv. 2.9s are not a fan of eating crankcase oil vapors.

Catch Can - weird (but good) results

So, changed valve cover gaskets recently. Noticed an undue amount of oil in the pcv vac lines coming off the valve covers, which seemed odd to me. New pcv 4000-5000 miles ago; it still seemed to be working fine. Just for poops and laughs, tried an experiment. Ordered a $30 amazon catch can...

CRC GDI and intake valve cleaner is the best thing I've found so far to clean the intake manifolds. Blows seafoam out of the water. Usually takes two applications a week or two apart on an engine that's never had the pcv garbage cleaned out if the intakes. First one melts the oil residues so they can be cleaned, second and beyond actually clean your manifolds.

Crc cleaner, seafoam, carb cleaner, maf cleaner.... all work for cleaning sensors. MAF sensor is to be cleaned with maf sensor cleaner only.

Plastic/polymer IAT sensor tends to perform better than a metal one should you replace yours - plastic does not heat soak as severely as a brass one.

If you do try to run a fuel system cleaner, the only one I've found that is not a complete waste of money is Liqui Moly Jectron. Does ok.

Dont listen to @PetroleumJunkie412. He is just mad because seafoam use to steal his lunch money as a child.

Seafoam is awesome.

 

[PetroleumJunkie412]

@Dirtman is just upset because the German made products work much better.

Actually im a fan of lucas over any of it.

But i will say the best shit i ever sprayed into my 2.9 was a grey can of "CRC GDI intake valve cleaner". Follow the directions good and i had great results

Definately looks like Chrysler/Dodge oe replacement parts. Looks like direct fit.
Do the handles also act as an extra lift point for a wrecker ?

 

[Nelson and Hudson]

Injectors rebuilt and reinstalled. Fuel rail bolted on. Waiting for intake manifold gasket in the mail. Turned power on to check for leaks. Seemed solid. Even heard the new pressure regulator releasing fuel back to tank.
