I will be going to the boat and want to pick up two 90 degree barb connectors for my spin on fuel filter on the boat as I am re-routing the filter. It currently has straight barbed connectors and using them puts a slight kink in the fuel line. I need to know the threaded size for the connector. I think the threaded size is the same for the ones I have looked at Walmart even though the one on my boat is a different brand. Does 3/8 sound right? It is a base (don't know the brand) that takes a volvo part number spin on filter. Thanks for any ideas as I would like to get them advance without having to make a second trip to the store.
