I'm installing a new gasket kit in a Holley NH and included is a felt piece that is to be used on the fuel line, but I don't know where it is supposed to go. Also, how is the float to be adjusted.
Gary, the felt piece is a compression seal that seals the gas line to the carb. You put this on the end to the gas line and screw the compression nut onto the carb which seals the gas line. You have to tighten it pretty good!!
The felt is for the old style line fittings. You shouldn't need it if you have new style fittings from the gas tank to the carb.
The float is adjusted to 1/4 inch above the gasket face. I hope you cleaned all the passageways out.
The felt will likely leak, you will probably need to fashion a more substantial packing.
Jack, Where do you take the 1/4 Inch measurement?
Just set the float parallel with the carb body, and it'll work fine.
I've used the original type felts on many gas lines and have never seen one leak. Just get the nuts good and snug.
I use these, no leaks and they don't have to be as tight as felt.
Gary, I've been told that to make the felt packing for the gas line seal, you need to use 1 1/2 of them in each cap. Haven't tried it yet myself.
I've had felt in mine for years with no problems. Wouldn't hesitate to use it again.
