Here's what is likely a simple question but talking it through with my wife isn't giving me the feedback I'm after...

For my carb fan I'm running it to a Spdt switch so I can run it manually (one of the on switch) and then auto (the other on switch). The auto side will be connected to a time delay circuit were it runs for a point of time once power (via the ACC) circuit is switched off...so it runs for 5 minutes when each time the ignition is cycled. I've got this part.

Here's the kicker. I'm running the circuit off a relay in my aux panel which is then provided power via another relay connected to the ACC circuit. This works fine for the manual on function detailed above and the trigger for the auto function...however once I turn the car off there is no power to the aux panel for the fan to run for the 5 minutes.

So...do I just remove this particular relay from the AUX panel (which is ACC switched) and connect power directly to battery via an inline fuse? This should work as long as my time delay relay trigger wire is connected to the IGN circuit somewhere...but then what about my manual on function?

I'm thinking that it may be easier to just use a normal spst switch and not try to have manual functionality for the carb fan. The switch would function like a kill switch for the fan. If it's on then the fan runs after each ignition cycle but if the switch is off then regardless if the timedelay gadget performs its function each ignition cycle it doesn't matter as the relay wouldn't get power.
 
Ordered a couple sheet metal plugs from this place earlier in the week. Rubber Parts Body / Sheet Metal Plugs - from RubberTheRightWay.com

These are for 1.5" holes, which are the ones in the 40 tub below the fuel fill spout. They're NLA from Toyota but these work great! I'm running 1/4" fuel hose from the tank expansion port to a charcoal canister mounted in the engine bay. Used a metal plug punch to cut out a hole for the hose.







Also wired / installed interior led tape lights and a backup lamp.



 
2 strips of those lights are going to be bright.
I did the exact same thing with my old 40 but only used one strip and I thought it was too bright.

I was hoping that wasn't the case. I tested them on a battery and they were bright but so hard to tell...

I can always clip one and use the other one somewhere else...maybe as an under hood light?

Under the hood would be perfect. That is exactly what I am using them for.
 
You don't need a manual on switch for the carb fan. Hook up the timer circuit to feed off of battery power and let it run for 5 minutes after each shutdown.
 
Picked this up from Fred earlier...couldn't resist going gear reduction.

I need to stop reading threads on this site...

Bravo. One of the best items I included when building the SBC now in the 40.

Edit for a question .... what are your exhaust plans? Nice and quiet or more noise?

I was leaning toward the setup I had in the last 40. Flowmaster can't remember the series...same that @mtweller has. Not loud but manly.
 
I like the charcoal canister idea on the fuel overflow tube. My 40 has a pretty pungent smell every time I fill.

It's pretty much a need with this setup. Stock, the 40 tank for this year vented into some crazy gadget thing in the bench seat and then a separate expansion tank in the rear fender...then back into the intake.

The new oem tank for this style only has two ports, 1) for the fill and 2) for the vent / burp while filling. The oem gas cap is not vented so it's either run with tons a pressure, drill a small hole into the cap (venting to atmosphere) or run a charcoal canister (which helps with the fume / smell).

You can run a GM style canister if you can't find a used oem one..they are disco now.

Flowmaster 40 series - as luck would have it :)
 
flashing some spline with a double C. 1st class sweetness right there. .
 
Picked this guy up earlier today, $3,700...not a bad upgrade from what I had before for just 2200 bucs net.

20' flat with 2' dove. (2) 5,200 Dexter axles, removable fenders. Trailer weighs ~3,000 lbs per the tag. Pulls nice but unloaded it is more noticable behind me vs my 18' 7k lb trailer. Not so much from a weight perspective but bounce. Need to make sure the coupler is adjusted appropriately. Should get a chance to test it out loaded in a couple weeks once my truck is ready for exhaust work.



 
Just found this thread yesterday and spent some time getting caught up. All your work looks great and your attention to detail is top notch! Keep up the great work!

PS nice tow rig, is it an LBZ?

Thanks! It's been a learning experience for sure...never done anything this comprehensive before. I'm already planning my next project too!

Yeah, the tow rig is an lbz, late 2006 build date. I'm owned it since 2008 and have contemplated selling it multiple times to 'cash out' based on its high demand from brodozer flatbills. Not worth it though based on how expensive new trucks are and this ones only got 115k easy miles.
 
I think it has to do with the emissions regulations for newer trucks. Even my LLY is worth a pretty penny. Here in Colorado, a clapped out 2nd gen dodge is worth its weight in gold.

What’s your next project?
