Difference between petcocks.

[Buffy1]

Had hydroloc this morning on my 99 Interstate first time in 14 yrs., not too bad. Looking at new petcocks does anyone know the difference between Interstate and Std/ tourer petcocks. Found some new ones on ebay for around $75. However they have part number 16950-MZO-033. Interstate calls for 16950-MBY-033 little more expensive.
  I know I could go with pingle. However, already have chrome covers for fuel shutoff and hate to leave a hole. Maybe I would need hole to reach pingle not sure.
 Any light on the difference would be appreciated.

Just my opinion but I would get away from that crappy stock petcock. The only way a pingle will fail is if you forget to turn it off and if you get hydrolock then you have a needle letting fuel past. Just finished fixing a hydrolocked motor sunday and I tossed the petcock and installed a pingle. Yes it leaves a hole but the extra security it provides is well worth leaving a piece of chrome off.

I don't really understand the part number differences.  The function is precisely the same on either model.

If by hydroloc you meant hydrolock there is more than a petcock failure is required for that to happen.

If the vacuum process failed you can repair it by rebuilding the petcock.  You will still need to address the carb issue.  If you want to remove the vacuum function exposure the stock petcock can easily be converted to to a non-vacuum petcock easily. If that's done an electric (Dan Marc) fuel switch should be added.

yea throw that oem one away and dont go with another oem,,the first one only lasted 14 years. just cant trust them.

Yes, I meant hydrolock. Guess if I had went to skhool I would have known that. Maybe the stock petcock failed after the first day of production and I just now had a chunk of dirt in the carb holding the needle open today, who knows. By the way, after I backed it down the driveway in 5th gear and expelled all the gas. I let it sit till this afternoon and fired it right up and took a ride. Brought back home and turned off the gas a mile away from the house and never ran out, let it sit in garage and idle for 5 min. and still didn't run out of gas. So, the petcock is definitely trash now won't shutoff manually or with the absence of vacuum.  Maybe just get a solenoid shut off valve and be done with it. Not tearing into the carbs quite yet as it seemed OK on the ride today.

My question is..."Which Pingle operates the same as the OEM"  I want a manual w/o vacuum but I want to use all 6.9 gallons and I want the reserve to operate properly.
The last one I installed only let me use maybe 5 gallons of the available fuel.

It sounds like the peacock manual switch is not shutting off but that doesn't mean the vacuum switching is not working. To test that you would need to see if gas flows out with no vacuum. Either way I think a Dan Marc valve with or without a pingle would be a smart move.

I went with a Pingle and left the chrome cover, took off the selector nob and covered it with Lowes plug.
I can reach under the cover to get to the Pingle without a problem.

That looks very good

... turned off the gas a mile away from the house and never ran out, let it sit in garage and idle for 5 min. and still didn't run out of gas. So, the petcock is definitely trash ... 

Bad test.

Mine (all three) will take about two miles to bleed the fuel from the carb bowls when moving.  Idling it will run a long, long time.

The failure of the petcock is more likely not shutting off at lack of vacuum.  I really never have understood correcting that problem by replacing a petcock that doesn't shut off with no vacuum with a petcock that has no vacuum shutoff to fail. 

You likely do need to at least rebuild the petcock and a DanMarc would be a good idea.

Flrider, what type of plug is that from lowes. I'm installing a golan valve and want to keep my cover in place. That was a great idea.

Which Pingle did you install?

Looks like a standard ol' sink plug to me?

I have the 1311-ch on both my interstate and my brothers tourer. He bought the tourer 3 weeks ago and I knew it had been hydro locked. Sounded like a can of marbles when the starter was engaged. Tore the motor out and replaced the broke gear and went through the carbs. It is now fixed and he has been riding it every day.i think it runs better than my bike so this winter im gonna go through my carbs and see whats going on with them. I have a 5th gear lug for some reason and I think it is linked to the carbs and maybe even the smog system.

I would try a Pingle again if i could make sure that all 6.9 gallons are available and the reserve works like the OEM.  Have you run the tank down to reserve with the 1311-ch installed?
Also, I would leave the chrome cover on and glue the old knob on just to eff with people.
