Default Siphon Fuel

Hi there.

Any suggestions how to siphon the fuel from my tank.

Got a bit of a sludge problem apparently.

Any advice will be appreciated.

Regards

sludge problem? What kind of engine?

It sounds like the issues seen with the Cool Fuel modules. They painted the inside of the cool fuel module. Gasoline would turn the paint to a sludge that starts to clog the injectors.

What age vessel? There was another issue with older pre-ethanol fuel that would cause the lining of the fuel lines to de-scale and cause clogging issues.

algae is a diesel issue. Is this gas or diesel??

Thanks for your reply.

I should add more information when i ask questions.

The 2200SC is 1993 model.

Is 1 5.7 litre Chevy with a Edelbrock carburettor.

It has a 100 litre under floor aluminium fuel tank.

i sent the carby away to be serviced. I have checked the fuel pumps and wiring.

It starts fine, but just runs out of juice.

The latest theory is sludge blocking the fuel intake.

So before I give up totally and put the whole boating experience behind me, I want to try and clean this fuel tank out and see what happens.

Thanks for any advice in advance.

How long does it run before losing power? A clogged fuel tank vent can cause this. Next time it occurs open the fuel fill cap and if you hear a air sound your vent is clogged.

Hi, I bought a cheap 12v fuel pump and fuel hose from Amazon and used this to empty approx 170L of petrol from my tank.
I put some long wires on it so the connections to the battery were outside.
Obviously you need to be extremely careful with petrol fumes.

Sorry for the late reply, I am in post surgery recovery and the boat has not been on the top of my list.

Originally the boat would get on the plane for up to 30 seconds, then it would just slowly sink back into the water. It would do this a few times before I would have to limp home with my tail between my legs.

I sent the carby away to be serviced and took most of the fuel out. Don't ask me how.

So the next time I took the boat out, it ran like it had never before. It wanted to go, but I kept it at 3000 revs with a smile on my face.
After 5 minutes it back fired and sat down in the water.

Same deal. I could get it on the plane for 30 seconds, before it wouldn't.
Limped back home with my tail between my legs again.

So while I have been recovering, I put some fuel doctor in that tank.

I am going to take it out this Sunday with an alternative fuel tank as well, to weather it's my tank.

Wish me luck, because I am tired of looking at it in my front yard.

Regards everyone.

This may be a bad ignition coil or ignition sensor. Both run well until they heat up then degrade.
