EVAP System

[QUOTE=crxguy52;1640114]I’m ok with a few additional pounds of unnecessary wiring to save myself tens of hours of work, not to mention debug time if I get it wrong.[/QUOTE]

Welp, that didn’t last long… I’ll include details of what all I removed in my (large and growing) wiring post.

I think I’ve removed just about everything I can from the car – now I can finally start building new things. I’d like to wait until Thanksgiving to order a mount kit (V8R usually has a sale on Thanksgiving day) and I’m taking a TIG course through my local community college starting in Jan, so I’ll probably hold off on the welding until then. That leaves wiring and fuel, so I’ve been focusing on those.

I got lucky with the fuel system – a friend of mine had a spare V8R kit he sold me for $50 (sans fuel pump and a few fittings). Considering the push-on to AN fuel fittings and c5 fuel filter \ pressure regulator are $17 apiece \ $39 and V8R’s kit is somehow almost $500 I couldn’t pass it up. I’m going to order a DW200 with Miata install kit and figure out the rest as I go. @gooflophaze and @rdb138 both said in their build threads that they’d run the fuel lines down the driver’s side if they had to do it again, so that’s what I’m planning on doing.

I did some digging on the evap system, and I think I got lucky with an 00+ car. @rdb had a ton of hoses to deal with for the tank vent, but it looks like that’s confined to the 99 model year – the 00 and 02 have much different layouts. I’d prefer the car not to smell like gas so I’m going to leave the stock charcoal canister \ air filter \ evaporative chamber system in place and just block off the (1/4″) port that would normally go to the engine. From what I can tell, the evap system normally vents to atmosphere through the charcoal canister when the canister drain cut valve (CDCV) is unpowered, so simply leaving it unpowered should allow the tank to “breathe” as if the car was off. I tested this by taking the charcoal canister out and making sure there was flow in both directions (in and out of the tank) through both the charcoal canister and CDCV \ air filter \ evap chamber. Seems simple enough, what could go wrong?
