It appears that the upgrade forces a login and many, many of you have forgotten your passwords and didn't set up any reminders. Contact me directly through helpmelogin@dodgecharger.com and I'll help sort it out.

^ You're still using a distributor so wouldn't it just go to coil negative?

Yes the stock tach would go to coil negative, but I was hoping there was a way to upgrade the guts so it runs of the Pro Flo ecu. The tach is not exactly accurate.

I gotta think there's a tach output somewhere on the Pro-Flo? If not I'd think one of the MSD tach adapters would do the job (8910 or 8913)

I see. I sent mine to Redline gauge works and the modernized the internals.  Uses the tach output from Holley efi.

(I also used an output to dual purpose the hood turn signals into a shift light)

Smart!

I will contact Redline and see what they have. Thanks

Is there a decent tool to add AN flares to my existing fuel lines without removing them? Gast tank and exhaust are out of the way so I have good access.

I never had much luck with these bar flare tools on brake lines but I guess double flare is trickier. I'll give it a shot. Thanks!

How about compression fitting adapters? If you have stainless I doubt it will flare, too brittle.  :scratchchin:

I'm using the stock steel lines. Both 3/8 for feed and return, although they shouldn't be the same size but hopefully it works. I assumed AN fittings would be best but I'm open to suggestions. I need flexible line to go from the stock steel fuel lines to the fittings on the fuel pump which are 1/4 NPT, and from the lines to the Pro-Flo 4 regulator which are -6AN.

I believe they make compression to AN adapters

That is correct. I used an LS fuel line setup and the compression to AN adapter is no sweat. Hot Rod Fuel has them.

Dino

Perfect! No need to flare then, I like that. Thanks guys!

It is crazy to think I parked this car in 2016 to go back to school. I have since started a new career, got divorced, and moved twice. I was going through the boxes of parts just a few days ago, looking at invoices from 10 years ago. The modern upgrades I installed are now vintage!  :lol:
Damn good to be back at it though!
