EFI swap in 1st GEN Truck

crash · Jun 23, 2009

I got the new vent hose and roughed in the ARB hose (had a spare to use). But you can see how I like to run the line. Its been my belief that if you run the line with something else it will aid in protecting it. I prefer to run it with a brake hose like I have done here. With this setup I have yet to have a failure on the number of rigs I have done.

Something else I have done for a long time--never run your line tight from the diff to the control valve assembly. if you ever have a break or anything of that nature--you won't have anything to make an easy repair. So what I have done is leave some loops up under the rig near the diff. It will pay off..

Looks like shit as usual

Now for an interesting part. I dug thru my stash of of EFI stuff and was able to find enough things to pre-wire the motor while I wait for the needed parts. So I pulled off the upper intake and threw in the fuel rail when I found something interesting.

Here is between the lower and upper plenum--thats as far as I can get it on with the fuel rail in place.

And here is whats causing it. The coolant fitting for the throttle body is making contact with the fuel rail. At this point I was puzzled and made the assumption there must be something different between the plenums also.

With the correct plenum its a perfect fit.

So I looked them over and I could see why this is happening. The eraly plenum dives down before the throttle body where the second gen does not..

So this tells me--we are simply going to have to run the second gen intake and plenum.

Good--then you can drag your ass a little north and we can wheel

Ok with the parts I had laying around, I was able to get the engine 100% wired up. I will try to get the other intake stuff cleaned up and thrown into the parts washer today so that will be ready to throw on.

Thanks for odie I was able to get an igniter. Got it mounted up (due to PS res I had to turn it from the stock mount) and plug wired in. I also had to wire an early style plug onto the ignitier.

Also got the new plugs/ plug wires thrown on. So besides swapping the lower intake the motor is as done as I can get it..

The 4th is past and so is the party--so time for an update. I got all the ARB stuff I needed thanks to my buddy chris at ARB...

So I decided to get the carrier fixed up-and let me tell you what. This was by far the hardest one I have done. Typicly what I see when the pinion goes into the carrier its a suttle rubbing against the carrier. With this one that was not the case--the pinion hit it pretty hard and mushroomed the carrier into the 4 crosspin retaining pins. Luckily the 2 smaller pin sit down into the carrier and I was able to drill the holes out and get them out.

The other 2---ya they were a pain.

I tried to grind the top to remove some of the mushroomed material and they would not come out. I finally had to drill below the end of the pin and force it upward enough to grab it

And now we have a perfect working carrier...

As soon as I got a ring/pinion I can get the rear finished up..

I also got stuff to finish the vent for the fuel cell. Since most rollover valves from what I have seen--only close when fully upside down--I went and put an easily accessable shut of valve in the vent in case of a rollover to the side.

And then ran hose and looped it around the air tank--pretty straight forward (looping it helps to prevent fuel leakage on slosh of the fuel--will sit in the hose and evaperate).

SO since I had the needed ARB good I would finish getting the lines ran. The front came with the hardline conversion kit. So I ran the line with the front vent line as I typicly do.

And ran it down the brake line--leaving extra looped for just in case.

I chose to run the lines thru the back side of the tool box. The only option running it thru the bottom was in front of the battery which might cause an issue of damaged lines if the battery has to come out.

And again leaving some extra at the pump--for just in case..

I removed the shiney lower intake and unfortunatly the gasket tore where it had sealer on it. At this point I still don't have the parts I need--but I didd get a bunch of small stuff I needed like hoses and such. So I decided to go ahead and bolt the intake all up to see what I might be missing and what I might need in the way of small stuff..

SO found out a couple small items I still need/will grab tommorow. But I also got all new radiator hoses and threw them on to make sure they fit. The one big different from the first/second gen truck in the coolant system--is how the temp control valve is due to where the coolant hoses are routed. To fix this I still retained the later model coolant hose pipes and got a 5/8" hose with a preformed 90--as you can see it worked perfectly..

Ok I am knocking thru this as fast as I can so it can be ready for the weekend of the 25th..

So for the fuel feed I was origionally was going to run a chev canister fuel filter--but I chose to go with earls adapter at the stock fuel filter. It turned out to be a nice simple/clean setup.

And I got the rest of the fuel lines done.

I went and grabbed a new o2 sensor. Its been a long time since I had even touched a 22re o2 sensor and I didn't relize the sensor unscrews from the 2 bolt mounting flange. So I got a weld in bung.

The exhaust had been sitting outside and waiting to be used, so I grabbed it and threw it in the rig and as I suspected--the new rear sock location is going to be in the way of the exhaust. So I ended up cutting every weld on the system and reconifuring it along with welding the bung in. So I am going to shorten the wiring for the o2 sensor and the wiring will be all done at that point.

the o2 location

I mocked up and tacked the exhaust, removed and welded it up. I relocated the exhaust hanger and made a bracket off the rear crossmember for it.

So my next step was to get the rear of the rig sitting on its tires--was making good progress. So I finally got the upper shock mounts made and buzzed into place.

So the rear springs are inboarded and origionally the shockes were mounted inside the springs--which made them pretty inboarded also--and taking away from there effectivness. Which with inboarding your springs from my experiance you end up with alot more body roll and need the shocks to be as effective as possable. So I chose to run the shocks on the outside of the springs and as verticle as I could get them without any interference from the springs. This si what I came up with.

So moving right along I got the new ring/pinion/master install kit on friday and had everything prepped and ready to throw the third together.

Here is where I hit a BUMMER. I found that the new cylinder cap on the ARB must be an updated version because the OD of the bearing surface and the seal housing assembly are larger than the one I took off. So I will have to get ahold of chris on monday at ARB and see about getting a couple more parts--was really hoping to have the rear done..

Might just be the angle but those lines look a bit too close to the muffler, even more so in the bottom picture??

Ya--that angle gives the picture no depth perception. The muffler is actually forward of the lines off the diff..
