Build Rockcod’s final ride, Morty the Forty

[cruisermatt]

there’s a schrader valve on the crossover pipe where you can use a mechanical test gauge. Personally I do not trust glass fuel pressure gauges with EFI on a wheeling rig. Especially when pointed right at an exhaust manifold.

If you want to be really trick you can use the Evap pressure sensor wiring off the ECU pins that you probably aren’t using for your swap and put a sensor here and rescale the table in HP tuners have fuel pressure readout on your OBD2 reader

Put that glass pressure gauge in the cab so you can see it.

Matt,

I took your advice and simplified/modified the adaptors for the injectors. Cut the middle plugs and soldered them back together, 8 less connections to worry about.
I had already ordered a new factory regulator because the old one was leaking. So I slapped that one on.

Thanks again!

 

[clrussell]

Good call.
LS is stupid simple and stupid reliable from GM. No need to over complicate it and change that.

 

[rockcod]

Well, you pretty much summed me up right there, simple and stupid!!

 

[rockcod]

I was on a roll and went ahead and bypassed the aftermarket regulator. I already had a length of hose that was the correct length and (2) 90* fittings handy, getting pretty good at make AN fittings now.

 

[rockcod]

Ok, I’ve deleted VATS, rear O2’s, EGR and EVAP stuff related to the factory fuel tank. I keep getting 2 recurring codes, P0405 and P0452 but the MIL does not come on. When I go into the ECU, it shows both of those have been de-selected. Why is the ECU still looking for them? What am I missing?

 

[rockcod]

The fact that the reader shows the status as “yellow”, is that why my MIL does not come on?

 

[rockcod]

Battery mounted, fuel lines run, engine wired and fired, I am now moving on to tackle the hydro assist steering. Having laid everything out to get an idea where everything goes and what else I need to make it all work together, I quickly figured out I need to finish the driver side tube fender for attachment points and figure out hose lengths. I am thinking I will mount the reservoir and cooler to the fender tubes. I’m making progress, albeit slow, it’s still progress and the parts inventory is getting smaller and that equates to more room in the garage!!!

 

[rockcod]

Found the mounting spot for the reservoir, in order to make it fit, a little bodywork was in order
The vent is mounted to firewall next to the clutch master.

 

[peesalot]

Is that vent PSC ?

 

[rockcod]

Yes

 

[cruisermatt]

not to keep hassling you, but I had a lot of issues with pumps running dry with the same PSC reservoir when I had it mounted in the corner like that since the hose would essentially make a "hill" when off-road. I moved it to the engine (alternator bracket) dirrectly over the pump and haven't had a problem in years since. Redline makes a nice bracket to do it for the stock Alt/PS bracket, are you not running it for clearance to your steering shaft?

 

[peesalot]

x2 what Matt said, that feeder hose to pump need to point down to pump, level or close to level may cause starvation as Matt has experienced.

 

[rockcod]

I am not running the factory bracket, not sure if that will work for my application, I’m using GOAT Built brackets . I appreciate the info!

 

[rockcod]

Today I had a little time and welded the tabs to the tie rod clamp from ruff stuff. Tomorrow it will get bolted on and I will be working out the stationary mount on the axle. Thankful to be doing something other than wiring!

 

[rockcod]

Mounted the power steering cooler, in the only place it would fit. Ran the low pressure lines and supply line from the reservoir to the pump. I know the reservoir is not a straight down shot, again I am limited on space under the height of the hood.

I took the ram to Bernell hydraulics in Rancho to have a tube stop installed, then I can determine where I am going to weld it to the axle housing and run the high pressure lines.

 

[rockcod]

After running around all morning, I was finally able to source 3 fittings I needed to make the high pressure hoses. Unfortunately, the ram is not done so I was only able to make the hose from the pump to the box. Progress is progress and that’s 1 less hose I have to make!

 

[rockcod]

Trying to finishing up the tube fenders today, I was making good progress until I ran out of shielding gas. I’m getting a gel injection in my knee on Monday so I will have to wait until Tuesday to pick up the new tank of gas…….hopefully.

 

[rockcod]

I had modified a bushing to fit the sensor that came with my temp gauge. It probably would have worked but the more I thought about it, the wall thickness was pretty thin and would probably crack and leak over time.

I went to the Auto Meter website and found they sell a bushing and a “probe-less” sensor for the LS head with the correct ohm rating for the gauge.

Now I’m wondering how accurate the temp reading will be since it is recessed so far in the bushing and not having moving coolant passing over it. Once I get the steering hydraulics ironed out I will get the motor up to temp and compare the gauge reading to the IR gun.
