So, I finally got to the fuel system since I knew my motor was now functional.

Got home and uncoiled my hose, "snap" it cracked right at the connection to the tank.
It looks like an easy fix... any ideas as to where I can find replacement hoses?

Then I popped off the cap and looked inside... Dear god... it was a rust pool... Not sure if this is salvageable or not...
Do I need to buy a new tank?

I thought the fitting connection to the motor looked ok...
I don't see any issues here... anyone else disagree?

Dump the old fuel from the tank, now pour in a hand full of 1/4" nuts and shake the tank. The fuel line can be found on ebay if the tank turns out ok. You could also convert the motor to a modern single line fuel system if the tank is shot.
 
No way I would mess with that tank, In the garbage and buy a new plastic one, fuel line and all before it screws up the motor too.

With an old 2 line system it's not as easy as just buying a new tank and single system fuel line.
 
That was my thought too... unless I am missing some type of "conversion kit" I don't know of an easy way to do this.

As a side note, I noticed rust on the bottom of the tank as well... it seems like with rust on the bottom of the inside, and outside... it is just one wrong poke to puncture the can and loss of fuel.

I think I may be in need of a new one...

Damn it...

He will need a fuel pump from an early '60's 7.5 HP motor. It will bolt on to the older motor in the same spot where the dual fuel lines go. It will cost about the same as an other tank and hose in good condition. You can get rebuild kits for the old tanks
 
would be easiest/cheapest to install a briggs diaphragm pump (less than $20 and about 30 minutes - ok, maybe an hour).

"upgrading" these old motors to single line (non pressurized) tank is simple.

you could also hit that tank with the bolt method to remove the majority of the rust. follow that up with a good period of electrolysis and it would more than likely be good to go.
concerns about particulates making it to the fuel system would be very low due to the use of an inline filter (everyone uses an inline filter don't they?).

'55 25hp Johnson with fuel pump...


'55 10hp Johnson with fuel pump...
 
Well I am glad to report, I took the tank down to the marine shop. This guy is great. An old salty sum bitch who knows his stuff... been building motors since he was 8.. Father taught him everything he knows...

Said the tank is very salvagable and the gunk I see on the bottom inside the tank is mostly gunk from crappy gas, and bad mixture of oil.

Said to try the pea gravel method with some hot water and soap... take off the top housing unit and get in and clean it out real good.

Even go buy some Evaporust to do the inside and outside to clean it up.

Trim the hoses about 6" on each end to get to the softer rubber and put the fittings on.

The only thing I need is a new gasket and a paint job.

This is great news... I am all for some hard work to save money.
 
Why would the hose 6 inches away be in better shape? Keep us updated on how this works out. Better get that inline filter as 1 poster suggested.

I would replace the old fuel hose with a new alcohol resistant one, along with all the fuel lines on the motor.
 
six inches was just an "estimate" due to gas sitting on the hose near the tank and drying out the rubber...

It wasn't a perfect method, but 6", seemed like enough to get to softer material...

I totally disassembled the tank this evening with a report when it is put back together.
 
Go on Ebay and buy a 25' roll of hose. Costs about $25, last time I did it, last fall. Nitrile hose, very good stuff.

The old hose is only a problem waiting to happen. Will probably be okay for a while, but replace it when you can.

Very hot water, a 50 pack of nuts and a shot of Super clean does wonders for the inside of a gas tank! I guess gravel would work, too, but not so keen on that idea. Might have trouble getting all of it out. If you miss a nut, you will hear it, and it won't hurt anything or get sucked up.
