: Glass Holley Sight Plugs?

Does someone make actual glass fuel bowl sight plugs for 4150 Holley carbs? :confused:

The Holley plastic sight plugs, e.g., Street Avenger series, seem to start dissolving instantly. :(



It'd be great if there was a nice non-leaking, non-frosting, non-dissolving glass sight plug that you could leave installed 24/7. :thumbsup:


Hope there is a source for such.

Thanks!

Good old fashon brass plug will work fine. Unless you are taking drugs and look at the sight plug and watching gas slouching around like a tumbling washing machine and look at the window and saying "Hey man... that looks groovy.... wow!!" :cool:

I set the float levels when I first put the present carb on our L78 and that was 7-8 years ago. I've never seen much reason to be checking float levels very often. They never changed. I just use the stock Holley stuff.

The Holley that's on my 57 Chevy truck, I set the floats 9 years ago when I built the carb. Never adjusted them again, never had the brass sight plugs out.

I don't screw around with it and it doesn't screw around with me.

Ever notice that guys don't constantly screw around with the floats on Q-jets, Carters, Edelbrocks, Webers, etc, etc? If the floats on those carbs were externally adjustable guys would be screwing around with them all the time, installing glass sight plugs, getting into debates on technique, frequency of adjustment, minute differences of fuel pressure and its' effects, etc, etc. The float/needle&seat assembly is not substantially different on the externally adjustable Holleys than those other carbs. Set it, forget about it.

Heresy, I know.

Know what else? I've never owned or spent even one dime of my money on one of those MSD red brick things you see on so many firewalls. Never will. Guess I must be just a total hot rod failure......

I think I'll change the air in my tires this weekend. Get some overpriced double throwdown super trick air and install it.

If you go for the aftermarket glass or plastic sight plug buy a good fire extinguisher.

Got no idea what your talking about. Mine has never leaked, frosted or dissolved. But then again I use gas in my carb.

IS there ETHANOL in the gas in Canada? That is what is eating the sight plugs.

Right now Allstate Carb has the aluminum bowls with sight glass for
$18.99 ea. - great deal.
I got a set yesterday from AED for $30 ea and installed. They are the shiny aluminum, so dont match perfect on the zinc carbs but work well.

Here in Ontario we have alcohol. At a Shell station, on the pumps it said, zero alcohol in the premium, five percent in the mid grade and ten percent in the regular. With the loss of gas mileage with regular, premium turns out not to be as much more expensive as it first appears.

Here in central Florida, all the "normal" gas (found at gas stations) has "up to 10% ethanol" in it. Every octane.
The place on the edge of town that sells race fuel also sells gasoline with no ethanol. It's 40 or 50 cents a gallon more than the ethanol crap at the gas stations, but people with boats and classic cars are obviously buying enough of it to keep them continuing it.
10% ethanol kills gas mileage about 10%... so... I guess I'll stop before it gets political.

Float levels/ sight plugs - I'm with the people who believe you don't need to mess with them once they're set.

Both Holley and Quick Fuel have sight glass bowls, the one above is the QF design and has glass on both sides of the bowl. Since real glass is used, the fuel will not deteriorate it unlike the plastic screw in plugs.

about the only way i know of to get glass is buy new bowls-try and get the ones that are also on the drivers side-makes sense, i mean where are you when you first turn on the pump, prob on the drivers side, so cuts down on the time a carb could flood by shorting up your walk, lol
