few updates this week gents.
I swapped out the factory pinion yolk for this upgraded yolk with 1350 ujoints that I got with the drive shaft. The only thing I dont like about it is it doesn't accept a dust shield... well it might but I wasn't able to find one for it. If I was taking it offroad it would be more of an issue I suppose. I installed it the sloppy way and just torqued the nut to 150 ft lbs. I wasn't about to go through the hassle of installing a new crush sleeve.
The new chromoly slip yoke with matching ujoint. I had to swap out the trans seal for the non dust boot style so we could use a shorter yoke which the drive shaft shop recommended.
The driveshaft is installed.. for now. The large crossmember you see in the picture below is a little too close to the shaft I think. I only have about 3 fingers worth of clearance. Which is about an inch less than I have before the suspension would be limited by the bump stop. This should only be about a half inch less than I had with the other shaft but with this being aluminum Im not comfortable with it so Im gonna have to do something with the crossmember.
I started on the fuel system upgrade. This sucked. I can only get the truck so far off the ground with jack stands which makes it a PIA to get under and work on.
I started by removing the tank and pulling the sender so I could modify the hat and install the 525lph "hellcat" pump. I wanted to upgrade the wiring that passes through the hat as folks have seen this burn up with large pumps. I didn't have any issues with the 400lph unit but didn't want to chance it. So I found a bulkhead connector and drilled out the original hole and feed the wires through. The factory bent up feed supply is also a small restriction so I decided to cut it off and use another bulkhead fitting to feed the new 10an supply line.
Once the fuel tank was back in the truck I could work on getting the feed and return upto the engine. I needed to install the fpr and the flex fuel sensor and fuel filter. I decided on a Deatschwerks filter because it was the only 10 micron filter that is 100% ethanol safe. And its cleanable. Anyway working with this PTFE line sucks hard. Especially if you have to work with it under the truck. Im glad Im using it but it sucks to fit the ends. If you look closely I used an existing hole in the top of the frame so I can fit an allen wrench into to adjust the fpr if needed.
The supply is routed to the passenger side front rail and the return on the driver side. I just did this because of how close the alternator is to the rail and the return fitting is smaller so it fit better. I dont like the zip ties but they will do for now.
I was able to power the pump late last night and flow some fuel through all the lines. I have one injector leaking at the rail so I'll have to pull the RH rail and see if I have a cut oring or something. Other than that I think the fuel system is done. Thank Goodness.
C10 should be ready to start at this point. I have a couple small things to finish up but Im hoping this weekend I can load a base map and see if she wants to come to life.
