I need to replace my fuel lines and look for a possible gas leak in my starboard tank. Do I need to remove the floor inside the cabin or cut the deck in the cockpit to gain access?

Phil,

Before you do anything drastic, consider looking around with an endoscope like tool or hiring that job out to a pro.

My 2010 has a very large cutout piece under the starboard sink/cabinet big enough to remove the tank without any deck cutting at all (also remove the starboard gunnel insert 8 screws to get at the tank fixtures).

I have read that all fuel hose manufacturers advise replacing all fuel hoses at 10 years from mfg date.

Iím surprised itís not 3 years or 5 years, arenít you? Sorry for the cynicism.

Good luck!
John

Consider a DEPSTECH endoscope from Amazon

$39.99 and uses iPad or smartphone for display. Has saved me a small fortune the past few years

That will help when I look for leaks, but not for changing the fuel lines.

I received an email from Tom Anderson at Northwest Marine Industries. He said I only have to remove the gunnel pockets without cutting the deck. Phew!

Sometimes a problem leads to a solution to many problems. We've had issues with gas fumes ever since we bought our Tomcat ten years ago. Most of the time we would fill up or whenever we went fifteen knots we were inundated with fumes. We had to drive with all of the windows open and deck plates off.

Last month we filled up in Marina del Rey. While filling up the starboard tank, the bilge pump came on. We rarely have any water in the bilge so this seemed out of the ordinary. I didn't notice any more fumes than we usually get. I guess I'm just used to the smell.

We made a few local trips and were shocked at how fast the fuel bars were dropping. They showed less than half a tank when we should have still been around six or seven bars.

On one of our last outings, the starboard motor quit as if it was out of gas. We made it back in on the port motor. I put five gallons in the starboard tank and the fumes were worse than ever. We went out again a couple of days later and the starboard motor ran out again after a mile. The primer bulb wouldn't get hard, so I changed the bulb and both water separators. The bulb still wouldn't get hard so I thought there might be a leak in the tank or crack in the fuel lines.

This morning I looked under the gunwale and noticed the gas filler hose was disconnected from the fill inlet. I tried to re-install it but it was too short. I had to loosen the clamp on the tank end of the hose, lift it up an inch or so and finally have enough hose to clamp to the upper inlet. I was able to clamp each end but will need to replace the hose with one a couple of inches longer.

I went to the fuel dock and filled both tanks. This time there were no new fumes. It took a disconnected hose last month to solve ten years worth of problems.

I will also say that you were incredibly fortunate that there was no spark in the wiring or some appliance which wold have ignited fumes...!!

Glad you found a "simple" problem.

That was a huge concern as we have two dehumidifiers, an air dryer, refrigerator, water heater, and a battery charger inside the pilothouse. We unplugged everything but the battery charger last month when the fumes got worse.

The bilge smelled fine this evening. We removed the cushions and carpet to air them out at home, opened the window in the head, and removed the deck plates. It's a little gassy in the pilothouse tonight but I'll check again tomorrow. I have a longer fill hose on the way.
