I have a 1630 FEL on my B7200D. I need to replace the hoses because they are falling apart. Does anyone have a list of lengths for the hoses? I could remove the hoses and measure them to get accurate length but i would like to only take things apart once. Are the fittings just standard 3/8" NPT? I can order single wire or dual wire hoses. What would be better? The dual wire has a high pressure rating but should i use the single wire because it would be more flexible?
