I’d keep an eye out one your local Facebook marketplace. Parts for these pop up if keep looking

I bought Justin’s remaining RD2-80cc from this run. There are a few N/A pumps remaining as of this post.

I have a question: I’ll be running this RD2-80cc pump on an N/A truck, until I can turbo and stud the heads. If I keep my foot out of it and pump screw turned down, Will I run into any temperature issues??? The website says it’s not recommended for N/A motors

I think that you'll be ok. It would be a good idea to install a pyrometer though.

Yep just get a pyro and pay attention. Shouldn't take long to get used to it. The timing may be off a bit since it'll have more fuel at the same pedal travel but you might be able to dial that in by advancing or retarding the IP. I haven't heard of people doing it so I'm not sure, but in your shoes I'd run it.

Thanks. I’ve bought a DTI timing kit so I expect to get it dialed in.

Anyways, here’s the pump!

I see you also got one of the latest run of pumps he made, I also have one. Let us know how it goes!

Pulled the old pump off last night

I’ll clean it up and inspect it before sending it off to Justin as a core.

Interestingly enough, I had a factory remanufactured pump on my engine too, and my truck only had 72k on it when I initially got it. Wonder what failed on the original.

Maybe someone ran used motor oil through it.

Are you saying that the pump I have here is a factory reman pump?

I don’t know how the world of reman works, but I wonder if that means it came from older tractor cores (older than this 1989 van 7.3). That would be cool.

I’m told that the whole truck has 270k miles, but I know that the motor has around half that number.

I believe that the truck has 270k on it, the steering wheel is completely worn out from where people have been pulling themselves up into the cab. The pedals show wear. The seats had heavy wear on them, too.

RD2-80cc pump is mounted. Thanks Justin.

The fuel rails have been as interesting as I expected. I’m going to try a new approach with the passenger bank.

1. With the injectors removed from the engine, gently plug each injector into the fuel rail

2. Similar to an injector thread protector cap, run down a lug nut or “modified” injector line to keep the injector held in place

3. Install entire assembly into the injector ports, careful of knicking the pintle tip.

4. Turn each injector one flat at a time sequentially.

Hopefully this will prevent the rail from going on lopsided and ripping an o ring

I assume its a factory reman, mine had the same exact tag on it

Problem: Installed New R&D pump, R&D fuel rails, and Facet 40290, but no fuel to injectors.

Context & Troubleshooting: Using twice filtered clean fuel so it’s not blocking the IP inlet filter screen.

Besides Fuel shutoff solenoid, What would cause fuel to not flow through IP?

I am getting fuel to the IP.

My fuel return system is not hooked up, but it shouldn’t need to be in order to get fuel to the injectors. No fuel comes out of the IP fuel return fitting on the front of the pump

Fuel shut off solenoid is clicking when you jump the post, and key is on. Very audible click, same as the other pumps.

I have been cranking it over for 5 seconds at a time with the Facet pump running.

 

[Nero]

Not sure, when I installed mine, I just sent it. Left all lines loose at the injectors, cranked until fuel squirted out of each one.
I also had the throttle linkage disconnected and the return spring off, so I just moved the throttle to wide open, and fuel came out easy.
What position is the throttle arm at when you are trying to prime it?

 

[hacked89]

Yea what Nero said but you need to crank longer intervals.
