Is that the line that has the flare connections on the top front of the bowl???
I just found mine to be cracked and leaking fuel all over. I tried to piece it together with a barbed connection and also a piect of 1/4 copper. I couldnt get either fix to hold. too much pressure.....Im wondering where you can get those premade hoses with the aeroquip tag on them. If this is the hose your talking about...you may need a replacement how to ge it working again. Im still looking for a replacement. Was thinking of getting some copper and bending and flaring it into place.
