Anyway to access the FRONT of a fuel tank on a 27?
 

I have fumes... I think the fumes are coming from this Area. I wonder if a hose or something is damaged on the front of the tank. If so, I'd be sh&t out of luck. right? when the boat was built, it looks the they put packing around the opening where the fuel filler and breather come out of the bilge. Was this to help keep fumes out of the cabin? It looks to have worked it's way out of the opening completey.

Anybody with knoledge on this would be greatly appreciated

my 29 has a fuel door under the back seat that gives access to the fuel gauge sender and thats about. I would think you would be looking at tearing the boat apart in this case. Try looking for a tank sealer.

If you remove the port side mirror in the cabin, you should be able to get access to the filler and vent hoses.

Sounds Like It Might Need A Tank. Hopefully It's Just A Hose.

Can you remove the tank by pulling the motor and cutting a hole on the rear bulk head? Slide it out the back? Or do you have to cut a hole in the floor\\?. I would like to find a better way to access the front of the tank if possible. If anyone has done it, please let me know

You have to cut the cockpit floor out to remove the tank.

like i said look around for a sealing compound like a BAR-S leak for a radiator(not sayin that would work just an example). Be worth a try before ripping your floor up and probably paying thousands to do it.

Thanks ! but if it is damaged. Stop leak will not hold it together. Because It was stonger than stop leak to begin with. It's probly cracked from ocean racing

Thanks Reggie !!!! Have you heard of this before in a 27? Do you think the tank might be cracked? Thanks for the info

Yes I've heard of that before, especially in boats built before 99-00. We did quite of few of them. Fiberglass is flexible where the aluminum tank is rigid. What yr is your boat?

92. It used to race class 3 at Longbeach. It only makes fumes when I'm goin over 50 . not when trailering, not when parked, not when goin slow , not rocking back and fourth parked. It doesn't leak a drop. really notice it at WOT. We have never smelled any fuel in the engine bay ever.

I'm thinking the fumes are not goin into the engine bay when goin over 50. Am I Wrong?



I opened up the air intakes and air exits on the side of the boat to get more air. Because I got a hunderd or two more rpms out of runnin w the hatch open

Take a small drill bit & poke a hole right on the floor through the firewall bulkhead. Go slow as to not hit the tank. That will tell you if there's fuel below the tank.

Thanks I'll try it. Can't be too bad removing the floor. Could make a nice access pannel w chrome trim , then throw some carpet.

have you tried pressurizing it when the tank is empty?

I have not. I did fill it one time last year.. As I drove away from the pump it sprayed fuel for about 10 seconds.. BIG TIME Pressure spray, laid a trail for a while when leaving the gas station.

This is really weird..

As soon as you go about 50 . you semell fuel fumes. ( rough water or smooth glass)

Anything under 50 No fumes . No matter how many waves you hit

AS soon as I run that front tank out of fuel and switch to the rear tanks. I get no fumes at any speed. Imediatly

If the tank was leaking, wouldn't I still smell fuel right after I switch tanks? I can't figure it out. It never leaked any fuel when it sit's either.

I repacked the opening w the filler hose and breather hose as well as the gap on the drivers side ( between the floor and the fuel tank compartment) with plastic and insulation and that seemed to cut the fumes down a bit. so it must be coming from a hose on top of the fuel tank in the front ? :eek:
