Black high pressure line is 1 wire -6 with crimp on 45* ends, the Eaton blue hose is -8 from the box and return to the res, they have all been angled to try and maintain maximum distance from the rams horn… Pump is fed with -10…
Looking in from the factory bumper, it may have to move a little once we start working in a winch…
Cooler has a full flow 180 which is direct from the box, then a 30* to send it back to the reservoir. Ran the return lines bonded together and put on larger hose to cover chafe points…Took 3 quarts of AC-Delco power steering fluid (P/N 89021182) without the ram.
We teamed up with Red Neck Ram for both of our steering boxes, we sent in boxes that needed rebuilding and wanted them drilled and tapped for hydro assist, Justin’s box has the fitting on top, mine has it in front of the piston. The turn around on the boxes was quick!
So the motor has been down on power and as of late the idle quality has started to suffer, so yanked off the air cleaner, to find that the throttle body has been drooling everywhere. Right injector spray cone looked awful “drooly “and the injector cone on the left was weakly pulsing. Pulled the entire throttle body cleaned the intake manifold then ordered up a rebuild kit and some new injectors since these are clearly done.
In looking around the pressure and return to the throttle body I found there was no fuel filter… So my 1989, with goodness knows how many miles on them, had been just pushing grit on through. Scooped up a Wix metal filter with 3/8 ends on it.
Pulled the throttle body apart on the fab table, o-rings that seal the injectors were so loose that the injectors just dumped out of the pod. Pulled the fuel pressure regulator and threw it and the injector pod in the sonic cleaner, bead blasted the base of the throttle body. Wound up bead blasting the injector pod as the gasket was being stubborn even after the sonic cleaning. Threw in the new injectors (61lbs/hr) new o-rings (with just a little bearing grease), reassembled the rest of the throttle body and sensors. Digging through some left overs I found a TBI spacer from several years ago, installed it with its gaskets and hardware.
Pulled the pressure and return lines out, cut them to size with a die grinder then used our hydraulic flaring tool to put barbs on the 3/8 hard lines. The pressure line had to be cut back a bit more as the hardline line was up against the firewall. Installed fresh o-rings on the hard lines inverted flair, and installed a pressure tester tap. TBI’s are sensitive to fuel pressure, they loose the midrange if they are running out of volume.
Using the 80’s pump and lines to one side of the new filter, used green shield 3/8” hose to make a 90* sweep into the hardline… (Pic just shows the back of the filter)
Aligned the old pan hard so we would have a measurement to list for trucks without a front bumper (and possible a lighter engine.) It hadn’t been done since the new lift was installed, it was out .5”. Will be replacing my barely used panhards with the new ones we are importing. Snapped the side shots after aligning the front, I have been pressure washing the belly of this truck (about 6 times thus far) as it has had several leaks that painted the entire undercarriage.
Quick side note after driving the truck is that the early brakes are far worse than the late style brakes were…
Intake went fairly easy (we joked I should have bought a lottery ticket), I got it to what you see in the picture in less than one day (not normal for me).
Spectre aluminum intake hood, to a silicone 45* reducer 4-3.5”, late model 80 air box, had to trim the tin around the mouth to make a suitable clamping surface. Need to get some clamps this week…
