Noticed a fuel leak which I thought was the crappy fuel lines between the injectors. Just swapped them out for new Goodyear hose but running the engine the leak actually appears to come from the plate which eventually fixes to the LDA.
I'm assuming its a seal on the bolt which screws into the cast part of the fuel system.
Knicking a photo from a previous post its the bit circled in black;

Any ideas what needs to be done fix?
