I will even make it easier for you. The Parker part number is 10M22C80MXS. The thds are M22 into a -10AN line. Hard to see but the red thing is a shut off valve so I can cut the fuel when changing the pre-filter before the pump.
The real stressful part is trying to break free that plug. Since the sheetmetal is thin, you need to take care. Load it up with penetrating oil and hit it with a impact wrench on a low setting. Keep hitting until it starts to turn.
