Here is the petcock;

that looks great, and i like the idea of the quick connect. Looks like I know what im getting for christmas.
Or what I did recently:
Vacuum flow control in the run position and it has Prime to fill up the carbs. You lose the goofy E-Reserve function.

I have used the Pingel 9050-AV Inline Vacuum Valve with the 229-8-6 90 degree 3/8" fitting mounted in the adapter plate for several years. I also use a Pingel inline filter. This eliminates the PITA of shutting off the petcock every time you stop. Flows more than enough fuel for FCR's.
Right, it wouldnt need to be a petcock, just an inline on/off valve i can route for accessibility. All sorts of room behind the carbs with those UNI's. So, adapter plate, fitting, valve, a filter, quick connects, im into over-engineered solutions

We gotta have beer some time... We can discuss our FJ related Rube Goldberg's.
right now my fuel line exits the petcock straight down the middle of the left bank UNI filter, in between it and the carb bodies. It was a squeeze but a lil lube and it fit right in. then the t fitting below the pod filter. Theres probably a good foot of hose under the filters, kind of coiled. For no good reason.

Extra fuel line on a G/F system??? Keep the RPMs low....
really, why? I had it in the upper register today and it acted fine. 8.5k in third gave me tunnel vision for a bit :)

Full tank, Ok, low tank, less pressure to feed the carbs. If you can keep your Kookaloo in the full to half tank zone than all is good. No Kookaloo (short bursts will work) in the low tank/pressure range with a G/F bike running on F/P carbs...
ah. ill keep that in mind, what does f/p mean?

G/F = Gravity Feed, F/P = Fuel Pump...
ah, but these are gravity frd carbs that had been converted to fuel pump by making the fuel lines smaller. which i have since reversed, making them gravity feed again. I think. The float valves were gravity feed size, the mains were 113 tho... air pilots 155, thing runs OK, may need the needles one clip down and the idle screws adjusted. seems to be a bit of a stumble at 0-1/4 throttle.

Oh... never mind, as you were. Sorry to bother you.... remember to contribute and attend a rally when you can... Still want to have that beer with you...
:drinks:
Man, im looking forward to next years east coast rally. And if im ever out west again, i will give you a buzz. I figure the extra fuel line gives me more reserve go juice... and next time i sync my carbs im just gonna put the tank up on sawhorses, which beats my 2 liter homemade fuel air bomb waiting to happen. :bomb: :bomb:

2 Liter??? Carb sync in 1/2 liter or less.. Get with the program... Some claim to sync with only fuel in the bowls...
uh yeah, and they fixed the 2nd gear issue with one hand tied behind... :crazy:

Get her sorted out and riding good, then lets talk rides... PCH, the 2, lots of really good SoCal stuff here.
eeehhhhh.... yeah. good word
I have never had a problem with half tank/poor feed. Maybe somebody's vent is not working. You can get CPC fuel fittings really cheap if you search online.....God I was pissed after over paying for years. They are there in any configuration for short money. Dual shut off, single shut off, 45 degree, 180 degree etc, etc, etc

That's why that vacuum Pingel unit works. I've tried more ways than you can imagine.

I'm currently using a set of pump carbs in a gravity feed installation on my '85 with a CPC dual shutoff connector and haven't had any problems with fuel delivery. Don't remember how low I let the tank get, but I recall running with less than a half tank with no problems several times.

Those quick disconnects seem real cool.
Any news on the vacuum operated Pingel petcock?
/Nat
East coast, i dunno. Nc, deals gap. Any fj activity there next year?
Randy, whats the center to center measurement for your adapter plate? I want to move to your set up eventually, but im going to have to come up with a lower budget solution in the meantime

Did you get that info?
46mm 7 bucks on partsnmore.com but im gonna wait a bit. I like the solenoid idea, So, adapter plate-barbed fitting -tubing-solenoid-tubing-carbs.
So, i went ahead and ordered some parts. One adapter plate for the tank, an inline filter, inline shut off valve, some 3/8 npt to 5/15 barbed fittings. Im going to play with the routing a bit, try to mount the filter where i can see it withlut removing the tank and the valve where i can get to it without taking off the side cover. The solenoid looks like a good idea too, maybe later... I like the idea of having an on/off switch for the fuel.
