1979 V-22 Outrage—Slow Fueling

Postby Spc337 » Thu Jul 12, 2018 6:35 pm

I've recently purchased a 1979 V-22 Outrage in very good condition. Our maiden voyage was great, everything was smooth as expected. My one concern is the fuel filler seems like it has a blockage as it can only accept a trickle.

I've checked the vent line and it seems clear. Now I know the usual suspicion is the tank and hoses, but both were professionally replaced: the tank in 2007 and hoses in 2016. Looking at the hoses behind the starboard cover and they seem great (Marine Fuel Hose on the Filler and Goodyear rubber on the vent line). I can hear, via the starboard outside vent cap, the fuel entering the tank slowly.

Before I have to get too extreme, what steps can I take to diagnose the problem to isolate the cause?

Would someone scope the filler hose to see if there is a kink or some other obstruction below the deck?

Should I blow air through the vent line to make sure it is escaping—but given I hear fuel, I'm sure that is clear.

I did blow on [the vent line], and [found it] had zero resistance.

Any thoughts?

What is the static trim on the boat when you are trying to add fuel to the fuel tank via the on-deck fuel filler port?

What are the date marks on all fuel hoses?

Do the hoses clearly state they are alcohol resistant?

Do the hoses clearly state their USCG rating designation as A1, A2, B1, or B2?

Since the tank was replaced in 2007 and the hoses in 2016, I would venture a guess that the fill hose is too long and either the slope isn't constant or there's a belly in the line. If there's a kink, it's too sharp of a bend where it goes under the deck. Consider adding a 90 degree elbow at the bend.

Marine A2 - compatible with Alcohol blended fuels. I didn't see the date but I believe it is less than 2 years old and looks in good shape. Even the bend doesn't look kinked.

I was filling the boat while on the trailer so a slight incline but suspect the same as if in the water.

ROGER on “slight incline”—but what way?

For proper fuel flow into the tank the trim on the boat must be down by the stern.

If the trim is down by the bow then fuel remains in the forward part of the tank and tends to block the vent line and slow the flow of new fuel.

I could understand how that could happen. On the trailer it looks to be stern down. However, my tank has maybe 20 gals currently so it would have to be an extreme trim forward to interfere in my opinion. If this was happen towards the end of the fill, I would see how this could happen.

Ok, so the [cause of the slow fueling] has been found,?and it is indeed a collapsed fuel filler hose. Seems the A2 is the correct hose and I can’t find A1 in 1.5-inch size. I did get A1 to replace the vent line and will install that with the new filler line.

Getting the old hose off was a pain but eventually got it done. The tubes from the tank have a light corrosion powder on them, and I’m assuming I need to clean them before putting the new hose on. Hence my questions:

—how should I clean the tank pipes?

—what is the best method to get the new hoses on?

—can I use some grease?

What everI use I want to make sure it doesn’t leave the pipe slick to the point the hoses can come off.

—where does the grounding wire attach?

I’m assuming to a screw on the filler cap on the gunwale.


Thanks

When I replaced those two hoses on my Revenge I used a little bit of grease on the tank intake and the 90 degree fitting. Made [fitting the hose to the tank pipe] easier.

A little bit of light sanding will clean up that corrosion.

My boat had a green [bonding] wire attached to one of the nuts and machine screws that hold on the fuel filler inlet.

A little soapy water should work to help slide hose on fitting

Alcohol will make a rubber hose much easier to slide over a fuel line fitting. And a day later it all evaporates away.

Well, I was able to get both hoses under the floor and to the access area. Both the vent and fuel hoses slid on to the aluminium tank easily with nothing needed to lubricate. This worries me a bit but the new hoses are the same ID as the previous hoses. Double clamped both so i’ll Check for leaks when I fill for the first time.

Argh! The hardest part was getting all three screws on the fuel fill fitting on the gunwale as the the hose made it near 8mpossible to get the nuts on.. after much effort, i was off to get fuel. This time, nothing backed up, admirable! Once the tank was full I checked for leaks and my concern was unfortunately validated. Leaking at the tank inlet. I have two hose clamps on, the same ones as before, the same hose size and brand too and cranked the clamps very tight. I scoped the hose when I got home and you can see a slight gap between the tank barbed fitting and the hose.

I can’t tell if that is because the clamp isn’t close to the end of the tank fitting or something else is different.

I’m wondering if there is a sealant I can use? Or maybe I should try T-clamps?

Wrap the fill pipe on the tank with an alcohol and fuel resistant wrap just enough to bridge the gap. Check with marine store for proper material.

I’ve put on some T-bolt clamps and will test it again in the morning. I tried to use my torque wrench (30lbs) but I got nervous as it seem extremely tight without hitting the limit on the wrench.

This hose will never budge. But does it leak???
