Hi. My name is ***** ***** I would appreciate the opportunity to help with your question.

Expert:  Steve replied 1 month ago.

are these the fittings at the tank or the throttle body?

tell me everything you can.

The O ring fittings above flare fitting on the tank side were changed. This may have solved the leak at front fitting, the rear fitting still leaks below the flare when you give it a little wiggle. Ordered new lines from goodridge. Challenge now is fastening lines at the other end, throttle body/fuel pump?
Expert:  Steve replied 1 month ago.

the part the fuel line connects to goes into another part, the check valve body, which may also be a source of a leak.

see the image on this link:


those parts are all 17 years old. I would change everything between the tank and the throttle body.

here is an image for the throttle body end:
