He is running a P pump cummins so I am unsure what your are referring to there. the fuel shut off solinoid is purely mechanical and has nothing to do with the fuel flow from the lift pump or fuel filter itself. The fuel shut down on a p7100 pump mechanically turns the racks and blocks fuel flow shutting down the engine.

The only fuel connection to the P pump is the fuel inlet and a fuel return. Both are banjo fittings. Using Teflon tape is a bad idea on those connections. Especially when a fuel leak in those places are easily fixed by new banjo washers.

 

Sorry I bailed from the Swap Meet before getting that Grill Shell to you, I was wiped out after no sleep Saturday night.

This past week I've had a nightmare of a VERY steep learning curve concerning Diesels and Fuel Problems. Air Intrusion is a massive problem on my rig with the 6.9, one of the hardest areas to find was that the Hard-line had rubbed through against the frame and would seal enough to run fine until the road got bumpy causing the line to bounce away from the frame and suck air in. Issue's with Hard-lines aren't too common but it's something to look at. Another of the many problems I had was the Tank Transfer Switch/Valve was letting Air in the system, so I bypassed that non-functioning POS also, then I blew 3 Return lines that tie between the Injectors. After all that crap it ate the new lift pump, slapped an electric pump on it tonight and did a 60 mile round trip with Zero issues. After the move I'll be running all new Fuel Lines from tanks> manual Transfer Valve> Electric Pump> Injection Pump.

My point is... Do you have any way you can Pressure Test your lines?

 

Yeah, I'm hoping it all works out as I hope it does. That's my project this weekend is to get that hooked up so I can go on a freeway run.

I will definitely try that. The motor ran perfect when it was in the Dodge. And I did loosen a couple of the lines on the pump when I was priming it. Thanks.

 

I think he meant where the injector lines thread onto the pump. I loosened a couple of those when I was priming it. But now that I think about it, those are probably compression fittings, so thread tape wouldn't change anything, right? I should check to make sure everything is tight though. I think it's definitely after the lift pump.

 

I think it's after the lift pump. Cause it starts after a few cranks, and stumbles a little bit with any throttle increase. After a couple of minutes it's ok.

I did remove the banjo bolts that are on the feed line into the filter from lift pump when I replaced the lift pump. Didn't put new washers on, so that could have an impact. I also loosened the banjo bolt on the overflow so I may need to check that again.

 

Sounds like you are making good progress. Your transmission controller sounds pretty neat.

 

I'm getting there. I hope to get the hood latch & trans controller wiring done this weekend.

 

Yes they are all banjo bolt fittings but mine have an extra port in the head of the banjo bolts. I think they are 1/8" NPT plugs.

 

That would make perfect sense then for the teflon tape. You had me lost on that one. Mine do not have the extra 1/8" ports. Would be a good place to plumb in a fuel pressure sender.

 

Got the hood latch support made tonight, painted and installed.



Here's some "in process" pics without the grille













And here's the whole I burned in my flannel while using a cutting wheel to do some trimming



Was wondering what was so hot...looked down and there was a small flame coming up my shirt. Ooops.....

On to the trans controller wiring tomorrow.

 

Grill inserts are installed. I must have put that first one in the shell 20 or more times. Second one went a little faster. Did the drivers side first



Then the passenger side.



Also did a little interior wiring for the trans. Got the manual switches hooked up for the overdrive and lockup. Sure makes a difference.

 

Looking great. You did a nice job on that latch.

 

Thanks. Stole the design from co425

 

For some reason I'm picturing lord of the rings. "MY PRECIOUS".



Looking good man! Looks like she'll be a daily driver soon!

 

Going to drive it tomorrow.

I took it on about a 20 min freeway drive. Running in OD with the TC locked up with no throttle it'd run about 600 EGT. I don't have a speedo yet, but was running a little faster than traffic so probably 65 or 70. If I got on it it'd go up to 1,000 pretty quick and even up to 1,100. What's too high for too long?
