The Purple Camaro

[fastazz81]

I had 1 in my circle track car at times , never had to lift in the corners. Pass a couple cars in the corners try to hold them off on the straight aways.
I offered it to bent, he chose this 406 crap instead.

 

[Bent77]

Adjusted the WOT AFR to 12.3
went to 10% accel pump

 

[Babaganoosh]

We need to have a phone call about afr, I don’t understand it completely. I mean I know what the numbers are but how can you tell if it likes it? Are you commanding that afr or is it running at that?

I’m commanding it. It’s rich, and that’s fine until I get it sorted

Missed my track date yesterday

Todays project is tuning and digging into why this fuel system isn’t 58 psi. Pump says it will feed 650 at sea level

Pretty sure this is ~525/525 ish

How’s the battery?

In Moab a few years ago that was my problem, an old optima would cause the pump to loose pressure. Fixed it by 2 battery’s and 2 30 amp legs from my solid state relay to the pump.

 

[Bent77]

14.1 above idle
However, I will take your idea to amp check it. Maybe it needs a bigger lead. Thanks

My pump has never been quieter, it was tricky for me to figure it out cause it would almost heat soak and loose it. I ran the last day with 6 gallons of water and 5 bags of ice. Every time the group stopped it got water on the tank.

Well after an hour of jockying around, I have a working fuel gauge again

Now for this box full of fittings, lines, and fuel regulator

 

[Bent77]

My learning for today

Pretty sure I had the gauge wiring come loose of the back of the gauge. Was wired correct at the back. Works now

Replaced the regulator and drilled out the passage through the sender plate up to .270” from .230”

Parker stainless 1/4”npt/-6AN fittings are larger inside than fraggola, earls, and aeroquips aluminum versions

Bought enough crap to feed it -8AN but haven’t yet changed it or the pump.
Pump is a Walbro gss340, and should feed Efi up to 630hp

Worth nothing that a -6AN line is .330” inside, and the PTFE line is .320” inside

 

[Bent77]

Forget to add, sits on 60 psi now

My local Parker store only carries JIC fittings (not AN), I would think the size should be the same but I wonder if the difference is the different styles of fittings or maybe it’s related to the materials?

Just curious. I’ve mixed JIC and AN fittings for years without issue even though the flare angles are different.

I have noticed that the gold (anodized?) JIC fittings build up a white crust inside after long use that I haven’t seen in my Fragola, Russell, etc fittings. I’m guessing it’s a reaction between the coating and gasoline?

Might be a reaction

These are definitely AN flare. My guess is they are just different, but the material should make them stronger even with a thinner wall

JIC and AN are both 37 degree flare.

Mark, I don't think you need -8 line, -6 is plenty with higher EFI pressures.

 

[Chickntrk]

Isn’t one of them 45 degree flare? Or ani thinking of something else?

 

[ktmoutfront]

Your normal brake lines are 45*.

 

[folkenheath]

Also the flared plumbing parts at the hardware store are 45 degree.

 

[6872xtc]

There are 45* and 37* fittings, yes. Parker says that their fittings will seal on either.
I have only had to use 45* fittings specifically, in a few instances myself, but the biggest priority here, IMO, is the ID of the hose and fittings.
I have seen some hydraulic applications where they didn't seem to worry much about a restriction caused by a fitting, I assume because they were using higher pressure.
I would think that this system would show more influence from smaller factors.

As far as the white corrosion and rust happening on fittings as @nvrenuf talked about, I have seen it on hydraulic lines which were exposed to a lot of moisture on the outside. (Mixer trucks and equipment) I don't know what would reduce it much, but I have used anti-seize on the threads occasionally to try and help. Possibly a placebo effect there, however.

drilling the trough plate at the tank to .270" is a 15% increase

Additionally, I've had a few other people besides @folkenheath and @Fastereddie say the -6 should feed it.
I'll start actually running harder and watching the fuel pressure
