Replacing a petrol fuel filter on a 94 Corolla. The replacement filter came with three new copper washers two for the top and one smaller size which is presumably for the bottom connection, (since there was not one in there, when we took the original filter off ?).
When its all reassembled, it leaks from the bottom connection. Is this because there should not be a washer in there ? or that there should be a washer and we need to buy some kind of sealant to put in on the threads ? Thanks for advice.
