I have a '95 Accord LX, need to know the fitting size/thread for the fuel-feed pipe,
it's actually the fitting that attaches to the bottom of the fuel-filter, what is the size and thread of that fitting? thanks guys.

 

I don't know the size of the thread but you will need a 14mm flare wrench to get it off.

 

Thanks, it is a 14mm flare nut.
I believe the fitting thread going to the fuel filter inlet is M14x1.5 , but how about on the other end of the line? (going to the fuel tank connector pipe?)

 

The big bolt on top is a 17mm bolt. I don't know about going towards the fuel tank as I haven't had to replace anything that direction yet.
