82 Aspencade.The rear shocks are slowly leaking down,think the O rings on the fittings are bad.Tighten down the hose from the pump to the rear and slowed it quite a bit.What size O rings does it take for these air hoses.??
I think # 25 is what you may be looking for. I believe there's five of them. You can probably find a standard 0-ring versus the metric that will be a lot cheaper and found localy, just take one of your old ones with you. I get mine at the local hardware store. Here's the part # and size for OEM https://www.partzilla.com/parts/search/H ... parts.html
