ordered second batch of parker fittings
Placed my order for the second batch of parker fittings. These will go into the regulated return system in the engine bay.
Found out since the last order that the trouble is the Viton seals in the VibraLok fittings. Easiest to circumvent this is to order the VibraLok fittings with the “standard” Buna N sleeve and the Viton sleeves separate. Exchanging the sleeves makes the VLV series, which is not stocked anywhere.
