depends on the size of the gas line and the pressure of the gas being delivered. More info is needed....
A natural gas line varies depending on the home. It may be a bigger gas line to cover a bigger home. Where as a smaller home would have a shorter and smaller gas line.
Gas line size is dependent on how long the line is, how many elbows and bends in the line, and what the line is serving, Leading to, does it carry enough gas pressure to serve appliance/appliances.
5/16 inch
depends on the delivery pressure of the gas....
400,000 btu's minimum ...pat What Pat is not considering is the size of your gas meter or the gas line to the equipment pad if there is one. If you are starting from scratch you still need to know the gas meter size and the length and diameter of the gas run. Absolutely critical to heater installations. Because of the existing gas line and meter you may be limited as to the size or BTU of the heater. k
First off where is it? If it is in line then you can cut that section off and replace it with rubber fuel line of equal size.
That depends on whether or not the connection to the new line is going to be the same size as the existing or if it is going to be a maximum of 1/2 the existing line size.
read the pool heaters manual.
Either 5/16 or 3/8.... Depending on engine size.
The diameter of the discharge line leaving the ac compressor would be smaller than the suction line, because the compressed gas in the discharge line is more dense.
I'm pretty sure the brake line is 3/16" and the fuel line is 1/4". I'm doing a complete brake line replacement on my 01 Z24 right now.
