It's in the officially unofficial official MRLS thread.

 

So I managed to reproduce the "miss" I was feeling at MRLS on the street. I'm down to maybe ~2g in the tank, and I can get it to "miss" on highway on ramps if I get crazy and HULK-SMASH the throttle. I'm guessing that I've found the same fuel return issue that so many others are seeing when they pull the internal regulator on an NB in favor of an external vac referenced regulator. With no data to back up my claims, I've decided to order parts in an attempt to fix it.

This adapter installs in the boss where the old regulator lived in the tank

- Listed as "For Toyota Starlet , AE86 and 2JZ Supra" This is the one @codrus told me to buy, so I assume its correct.

This is the adapter that changes it from -6AN to a 3/8" hose barb:

- Mine ended up being anno black

And this is the Gates submersible fuel hose that goes inside the tank:

- It needs to be listed as submersible. The external jacket and some of the internal structure of standard fuel line is NOT rated for long term submersion in a fuel tank. You have been warned.

The packages ended up looking like thus:



And once its all stuck together....


So now I just need to pull the pump hangar assembly, bolt it up, cut the hose to length, add a zip tie to keep it from wandering around, reassemble and give it a rip. Here's hoping!

Unfortunately its become cold and rainy out here, so HULK-SMASH throttle activities are going to be curtailed for the time being, but I'll figure something out.

 

In lieu of the adapters, 30 seconds with a hacksaw will give you something to slip some 5/16" hose over. It's not under pressure.

 

Oh I know. For the majority of people following along at home that would be the easy button, and probably the "right" way to do it. But why do it "right" when I can throw $30 worth of parts at something?

Unfortunately I need that flange intact. For reasons.

 

That return set-up will do it.

But, please, put the COP’s on, at least. Or buy my ‘99 coil packs for back-ups and add to your parts bin.

 

I have 3 NB1 coil packs, how many more would you like to sell me?

 

You need at least 69 more. And never install any of them.
In fact, I firmly believe you should switch to 1.6 ignition and batch fueling.
I'd suggest carburation, but that's too much work.

 

Get rid of the coil packs, cut a hole in the firewall, install a distributor.

Carburator? Pshhh. You just need a tube going from the tank to the intake mani. No regulators or anything like that. Thats how you break stuff.

 

Miata is currently shod in 195s on stock 15x6 and loaded to the hilt with various extra Miata parts while I'm preparing for the 5h drive to NorCal. WHAT COULD POSSIBLY GO WRONG?!

 

Swing by for a pit stop if you want.

 

 

Absolutely! I'm just down the road from T-Hill now. Not as class as I was to MRLS, but still pretty darn close.
Thanks Carlos, but we stuck to I-5 this time. I appreciate the offer and the wife and I will have to take you up on that another time

NB made it just fine to NorCal without explodificating, so at least that's one thing I can check off the list

 

Wait, did you move?

 

yes. he couldn't stand living so far away from me

 

Nah, he just wanted a better Sheriff.

But who's going to grow my lettuce now?

 

Yep! New jerb and everything! I'm a fat cat government employee now
This is true, we met up yesterday and I received stolen property acquired more Subaru parts
I've been in NorCal for 3 weeks and I've already bought a gun and started growing a beard. No State of Jefferson tattoo though.
You should try growing it yourself, its not terribly difficult. The challenge is scale.

 

Stop by anytime, it's more fun around here in the summertime anyway.

 

I was going to say "only one?" but then I remembered the one-per-30-days rule applies even there. Lame.
