Hi,
Adjusting gas pressure should only be done by an hvac tech and is not recommended for DIY.
Gas Valve # 7956 - 336P can be seen and ordered here by paging down :

Will most likely also need Mounting Bracket # 7705 - 5101.
After adding gas valve to cart, type mounting bracket p/n into search window.
The gas valve is the correct replacement, but will not look like the old one and may or may not have same piping configurations.
Thanks,
Robert
