So I got the 1050 mounted, but it leaked and wouldn't give any gas. Not a big surprise, a used carb, unrebuilt, you don't expect to work right off, it was a quick and dirty long shot, I admit it.
Meanwhile, I got busy installing a fuel pump, the much-recommended Walbro GSL-392, and a Holley regulator. For some reason the builder installed the fuel tank, which looks like a stock A-body tank, except it's dropped in the top in a cutout where the spare well would be, and it's backwards. Not by accident, some effort was made to make the fuel filler work this way. I can only imagine it's so upon acceleration the fuel sloshing backwards will go toward the inlet & sender rather than away?
Anyway, there had been a fuel system in there, but it had been pulled out at some point, leaving just the single aluminum 3/8" line with slightly mangled ends.
I'm making an effort to plan carefully and keep my goals in mind. The ultimate goal for this car is a recreation of a period street racer, built with mopar parts as much as possible. It's not my goal to make it go faster, or do modern upgrades beyond a certain point. Also, the goal right now is to get it rolling under its own power so I can get it up on a lift - then I'll replace the line, but for now I'll work with what's there.
I installed the fuel pump on the rear crossrail, directly behind the license plate - kind of a strange place and probably not the ultimate safety feature, but it's close to the tank inlet, and is good enough for now. The regulator is a generic Holley installed deadhead fashion on the front fenderwell, using screw holes that were already there - same part was probably there before.
For now I have a rubber hose from the regulator to the fuel rail, with a nasty clear plastic inline fuel filter - I like running those for the first couple of tanks to keep an eye on whether there's crud coming from the tank. Then I'll replace it with a braided line.
Anyway, I had a decision to make when the 1050 wasn't working. The tempting thing to do was to yank it off and swap one of the other Dominators I have without rebuilding it, like the 1150, and see if I get lucky. The wiser thing, I reasoned, was to take a core AVS and rebuild it with a kit I have on hand, and mount it on the tunnel ram without the adapter plate. That would be a far more 'known' situation, with a carb probably far closer to streetable and far closer to what you's expect to run well on this motor. Better to be sensible.

Nah!
Off with the 1050, on with the 1150. The marine fittings really helped make the changeover quick. The 1150 had been the main carb, there others were backups. Fingers crossed!
And she started RIGHT up, and runs REALLY well. The progressive linkage opens very smoothly, no flat spots or surging.
