So, after having my rotary pump resealed with DGK-121...my truck has become harder to start. They stopped the fuel leaks in the pump, so let's assume that the pump is not the problem.

Here are my first thoughts on were the leak is.

What is the red arrow pointing to? There are two copper crush washers there that I need. Is that a fuel line or what is it?

Is the purple arrow pointing to a potential spot for an air leak, or should it be left alone? It appears to be a flare union.

The green and blue arrows are for banjo bolts that appear to use plastic washers. Any source for those? They were in bad shape and I'm betting that's the cause of my hard to start problem.

Once the truck is up and running, it runs great.

Any ideas/help?

 

The red arrow is boost pressure not fuel.

 

Cummins, Geno's Garage, and GDP all sell the banjo bolt washers.

Looks like your fuel heater gasket is seeping too.

 

Thanks guys, and yes the fuel heater gasket is also one that I'm trying to locate

I head over to cummins and see if I can round out these washers and fuel heater gasket.

 

Okay, just want to ask another question about it. Once it's unbolted from the injector pump, it swivels freely back and forth, like it would be or could be a source for an air leak. Is this also normal?

 

Is the connection at the intake tight? Mine will swivel around when loose like when I am taking the afc cover off.

 

Try snugging up the 13 mm nut that holds the tube in the fitting.
