Overall Assessment

Customers appreciate the product's convenience, highlighting its easy installation and ability to check the carburetor's float level without spilling fuel. It significantly simplifies fuel level adjustments, eliminating the need to unscrew float level screws. However, several customers found the product's material quality lacking, saying it breaks under pressure; particular criticism was aimed at the product's poor fit with side hung bowls. A few also reported issues with an oversized O-ring diameter causing distortion and sealing issues. Despite this, the product's clear vision feature and neat appearance were positively noted.

A Must Have Product

Setting the float level on a holley carb is not easy and with these site plugs it easy to see the fuel level without having fuel leaking onto your engine. I can't see any racer not having these in his or her tool box.

No Due to the part dissolving before I could get floats set

I bought two sets of these clear view sight plugs put them into two holley carburators before i could get the float set the large part of the sight plug had fallen onto intake leaving partial threads and plug in carb bowls which caused me to have to remove all four bowls get partial threads out and debris out of carb. Had to use spare bowl gaskets that was ordered for later use on same order from speedway at that time.

These did not fit the holly side hung bowls. Due to some casting. That wouldn't allow the plug to sit flat. Maybe if the head wasn't so big they might have worked. The Holley brand sight plugs don't have as big as a head on them. My carbs are 9776 side hung bowls.

They break under pressure

Don't over tighten them into the float bowls and make sure your fuel pressure isn't too high. I had mine at 5.5 PSI and they still broke.

Used while doing test and tune at the track. Broke easily. Couldn't complete setup at the track. Had to take it back to the shop, remove the bowl and take it out from there. Went back to original style.
