Insects in fuel pipe vent

[Jacqueline]

I have a 1992 Sea Ray Sundancer 290, twin petrol engines.

Can anyone help me with advice on how to unblock the air vent that serves the fuel pipe? I had this problem last year, there was an insect nest or something in the pipe that leads from the fuel overflow on the hull of the boat, to the ingoing fuel pipe.

The problem is that is takes forever to fill up the fuel tank because the pump keeps switching itself off due to the blocked air vent pipe.

The service guys came and unblocked the pipe last year and it was fine after that, but some more insects have caused another blockage over the winter. I do not want to pay for the service guys to come to do something that is probably quite easy to do myself.


I need to know:

1) How to access the pipe
2) How to identify the pipe
3) How to remove it
4) How to clean it
5) How to reattach it securely

Any advice from anyone who has experienced this problem would be gratefully received.

Thanks in advance!

Find your fuel tank.
Your bug issue hose. The vent hose is 5/8" ID. The 2nd to biggest hose on the tank.
Your fuel feed hose to engine is 3/8"
Fuel tank filler is 1 1/2"
All connected with hose clamps.

Disconnect vent hose at fuel tank. Blow out with compressed air.
Replace the stainless vent pipe/fitting the goes through your hull with one that has a screen.
They screw on. Problem solved forever.
If going that route. Just buy new vent hose. get the lenght measurement from the old hose.
