I had a leak on the low pressure line of the AC system on this truck. I had to order a hose assembly which has both low and high pressure lines. My question is? Do I have to replace the accumulator too since it was left open while replacing the lines. It took me about an hour to replace both lines and thats how long the connection was left off the canister. Thanks for your help.

Thanks for your advice. I went ahead and replaced both the accumulator and the orifice since I had the grill off anyway. I than evacuated the system and than checked for leaks. No leaks at all. Recharged with 32 oz of R134 and the trucks AC temperature is 40 degrees. All looks good.
