Access to forward fuel fill hose??

[bobk]

Does anyone know how to access the compartment that the forward fuel fill hose and vent line run through on a series I 48MY?

We suspect the fill hose is leaking and since it is not original, it has been changed one before, but neither I nor a good local mechanic can see how to get to it. Each end is accessable, but it runs down under the electrical panels and galley floor level to the tank. I have the various drawings that Hatteras was able to supply, but they provide no clues.

Alternatively does anyone know if these hoses were strapped down? Perhaps a new one can just be pulled through???

The filler hoses on our 53 are all strapped down so I ASSUME it was the same on all Hatts. As you noted, it makes it extremely difficult to replace some of the hoses. I'm trying to replace a deck fill for the forward waste tank and have yet to figure out how to do it - there's no slack in the hose to pull it up more than about 1/2" and no way that I've yet found to reach all the attachment straps...

My fill hose is also strapped down however it is somewhat accessible on my 41 c however I've replaced several Bildge discharge an a water fill hoses that were strapped and not accessible. It leads me to believe that alot of the mechanical stuff was done before the interior was done without thought of the next guy. It seems I'm always the next guy.
Good luck Jim

Good one!

Why not have the next guy be the next guy??? OBUBBA for change NOW!! ws

This is likely the centerline fuel tank...regardless, you know where the deck fill cap is....on my 1972 YF (an early version of your model) that fill was on the port catwalk, forward of the port wing door...

You have to get under the catwalk from the inside... adjacent to that deck fill plate.....likely the aft part of your salon, by removing the plywood side panel(s)....You may or may not be able to access the fill hose within the engine room....My fill hose connected to the top of the centerline fuel tank at the aft end of the engine room, flush with the engine room floor.

An alternative approach might be to remove the deck fill plate from the catwalk, and if you have access to the fill hose in the engine room and can be sure it's free there,and at the tank, you might be able to pull that hose up thru the catwalk....tie a cord to the bottom end so you can help guide the new hose and route it the same way....if that's what you decide to do.

Our boats seem to be quite different. The fill is on the starboard side foward of the saloon. It runs through but below the 6" space that houses the 12V and AC electrical panels, then goes below the dinette sole. Access to the fill fitting is easy as is the hose at the tank. What I'm looking for is access to the lower part of the hose run. I'm sure it has been changed out once before, but it is not obvious how. Maybe Roger will see this and comment.

On my 1966 41 convertible the fuel fills run from the gunwale to the fill. Thats about as similar as the last comparison is't it Bob?

Roger is your best bet short of Hatteras having drawings. Do you have the drawings for your boat? I got mine a while back and they do have a lot of helpful information in them.

If your fuel fills are anything like mine ('69 45C), the fill hose (2") was double clamped to the filler cap and bonded there, and ran straight down about 4' to a 90 degree fitting where it was double clamped in the ER. When I replaced mine, I removed the clamps in the ER, unbolted the filler cap, and pulled the entire assembly up through the deck. Nothing was holding the hose for that 4' vertical run.

I'm hoping Roger will see the thread and reply.

I do have all the drawings for the boat that Hatteras was able to supply.

I'm hoping mine will be that simple. The 2" hose drops almost 8' then has to go horizontally about 5' and finally forward at a 45degree angle to the tank fitting. If there are no clamps, it will be a breeze.

Whew!! Dodged one bullet. The mech found a way to look at the fill hose, including a bore scope. The area had saw dust from the original build, but it was dry with no sign of fuel. So the hose and vent line are good.

Now the question is how am I getting fuel on the starboard battery shelf. This all started after the starboard transmission was rebuilt at Harbortown and has been intermitent since. Seems like if the foward tank is filled I find a leak... upwards of a gallon which I have collected by draining the shelf into a bucket. This shelf is not fastened to anything where there might ba a fuel source. The fuel supply and return lines run inboard of the stringers that the shelf is mounted on. More puzzling is I only use the forward tank to supply the port engine. It doesn't happen when the forward tank is half full. Nor does it happen when running on the aft tank only.

Any ideas? What could have been disturbed on the engine that could have sprayed fuel on the shelf but no where else? And as much as half a gallon? I have collected that much overnight from the flat shelf.

Bob you got the fill checked how about the vent line?

No Idea about your boat just thinking out loud
Good luck see you in Mystic

How about something stoopid like a leaking Hobbs switch or part of the secondatu filter system? Climbing around working on gears, you have a tendency to kick or grab stuff and nor even realize it... ws

 

[Boatsb]

Bob if you can send a picture or two I will run it past Dennis and Ken. They may have some insight.

Dennis did see the leak the very first time it ever occured. It was evident when I did the ER inspection after he fixed the gear. No idea what was going on. My initial thought was he might have up ended a can of fuel that I keep in the area for priming. But that possibility has absolutely been eliminated. When it happens, the amount that drains is really perplexing.... 2-4 quarts.

I have also run this past Bruce Morrison (lots of pictures and dialogue) but his only thought was refuted yesterday.

No such thing as a stoopid question Bill. I had looked carefully at the Hobbs switch and secondary filter and can find no evidence of fuel. they would certainly be in the right area to be suspects.

When I get the leaking output shaft and seal repaired (yep, same trans that went TU last November), my mech is going to try to throttle the return line to see if some increased pressure will show up something.

Theres always the flourescent dye and blacklight trick... thatll give you instantaneous results. Do one tank or racor at a time. Just a thought... ws

When we went thru the factory in May 2010 you could see where interiors were being built to be dropped into the hulls.Robby
