Gas line filler

[Dubbies]

Hey guys, I'm new to boating and I got this gas filler for the boat. I'd like to install one since I got a larger tank for it.

This one came with the boat, the guy never put it on. It has some sort of build up on the inside. What is it? Is it safe to use? Is there a good way to clean it?

I don't mind buying a new one... Just figured I'd save money if this one is OK.

I take it that by gas, you refer to petrol?

If you plan to change your tank(s) layout, try to get it right. Safety first (location (weight distribution), lines, hoses, fittings, valves, vents, fillers, water separators, filters etc.).
A Google for boat petrol tank installation requirements will give you inspiration.

Clean fuel is a prerequisite for engine(s) to work. Anything getting in contact with fuel must be clean.


The fillers themselves need to be fitted to prevent (rain-)water from entering the tank, so proper sealing is mandatory. Same goes for vents.

Is that a portable outboard tank in the background of that piccie? What sort of boat and engine? Be very careful messing with petrol installations.

It is just oxidised crud in the alloy. Likely from the filler nozzle banging against the side wall and exposing fresh alloy, which then gets contaminated, with dirt and stains. I would not worry about it, clean up if you wish, fit and use, save yourself some dosh. Try hot soapy water and a green scouring pad. If that fails, hot soapy water and wire wool. Wash well in clean water to remove wore wool strands.

I forget that people call gas petrol over there. Sorry, I'm from Canada where we are stupid can use weird words








I'm putting in this bigger marine fuel tank. I believe all I need to do is run an inch and a half fuel line into the tank, run a vent to the side wall and hook up the fuel line to the motor but that's all the same as the one in the existing tank so that'll work.

It was just taken out of the guys boat a month ago. Very clean.

I'd run a bonding wire between filler, tank, and motor, you don't want static sparks when filling, but as long as filler diameter matches tank filler diameter and the linking hose is up to fuel then go for it.

If you ever need a survey or if there are local regulations it is better to use marine fuel hose.
SAE J 1527
+1 for ensuring the filler cap has a good waterproof seal. Contrary to various Youtube videos, engines do not run well on water

Awesome thanks man. I got my 1.5 inch tubing already. Just need one for the vent now. I'd assume I need the same fuel line for it. Hard to find the right size, 4 places locally are sold out so far.

What's a bonding wire? Is that like a ground wire?

Exactly that, just a wire(multistrand flexible, tinned if you're going on salt water) joining all the metal components together.

 

[Dubbies]

Ah cool. Great tip thanks.

Yah it will never be in salt water. What do I connect it to?

 

[penfold]

Depends on the boat's set up but between the fuel filler and the tank at a minimum.

All metal components of filling system should be grounded to a fitting which makes contact with the water.

There are 2 American Boat and Yacht Council (ABYC) standards which apply in the USA to gasoline systems (H24 and H25)
In the UK The best guidance is probably to be found in chapters 2 and 5 of the Boat Safety Scheme.

I dont know what guidance or statutory requirements may apply in Canada.

This is a relevant extract from the Boat Safety Scheme

Petrol fuel system electrical bonding.​

This section addresses the hazards related to static charges and petrol vapours. The build-up of static charge, from fuel flowing through the filling pipe could result in sparks, which in turn could ignite petrol vapour​

Are all metallic components in the petrol filling and tank system electrically bonded to earth? Check all petrol filling and tank systems for the presence of electrical bonding. Where petrol filling lines have non-conducting sections, an electrica bond between all metallic parts, e.g. tank, filling point and any intermediate hose connectors, must be fitted. Where the deck and hull are non-conducting, or where the filling point is non-conducting, all metallic petrol tanks, and all metallic petrol filling components, must be electrically bonded to an earth point in direct electrical contact with the surrounding water.​

Staic electricity build up can be a real danger. Hence codes require bonding wire fuel filler to tank to engine or power negative. Sorry to harp back to aircraft (petrol) it is mandatory practice for the fuel delivery truck to ground the truck to earth points around the tarmac and to the aircraft. The aircraft will have a tab near the filler where the filler nozzle is grounded to the aircraft by a wire before the filler cap is opened. Hence any spark from static is dissipated before opening the fule tank filler. So perhaps a few ideas there. ol'will

 

[Dubbies]

So do I just connect a wire to the prongs on the black thing on the rank and attach it to the bottom of the boat? Or the wooden floor?

Any other ways?

 

[penfold]

The flat black circle is the fuel gauge sender. You could use one of the 5 fasteners holding the sender in or clamp the wire terminal(the wire should have a crimp terminal on the end) to the filler pipe stub with a hose clamp.

 

[Dubbies]

So where I fill the fuel to the tank? Doesn't it have to be to the boat as well?

 

[Dubbies]

Also, I have two tanks... I'm going to use the second one here...





I don't know what it's called but that tells you how much gas is in the tank, correct? Shpuld I take that one off the first tank and add it to the black one there? And then just fingers crossed it works?

 

[ChromeDome]

Many AMF Crestliner models are aluminium which changes the game a bit re. bonding/earthing/grounding.

If alu it needs to be considered, IMO

 

[snowbird30ds]

If you connect from filler to one of the 5 screws on that sender then from there to the body of the motor any static should be discharged through to the water.
I have a 12v transfer pump for shifting diesel and often hear static crackling when in use, not such a problem with diesel but a different story with petrol, and if the tank is full of air (well that is why you fill it after all) it's a much bigger bang.
