its a fuel inlet filter. necessity? no. good to have? sure if you dont have a good filter inline... its just hard to get to/clean/inspect.
I was curious because the new hard line I bought doesn't have the same shape on the inlet that it sets in.
Pics would be helpfulYou need to make sure that the thread/fitting design is correct or you could end up with a leak (fire!).
I believe it 's also a restriction you don't want, especially if you're running a filter. ( my 2 cents for the day )At least the price is right. LOL !Sent from my iPhone using SoCalJetBoats mobile app
