Carb fuel connection

[Ken B]

I do NOT need this now but it drove me nuts for a day trying to put something together.

I wanted to use a 1 gallon gas tank and gravity feed the carb from it. I am restarting an engine that has not run in 19 years. I have not drained
and clean the tanks so just to get this running I need to attach the tank direct to the carb and gravity feed it. The problem I have is I was not
able to come up with the appropriate 3/8" reverse flare fitting and adapters or elbow that would clear the thermostat housing to connect the tank hose
to.

What have other people been using?

Today, I stopped by the local auto parts store for ideas. The guy that makes hydraulic hoses made me up what I needed out of 3/8" tube and bent me a
close bend on a machine that they have there. I could not do that bend with my hand bender. Total cost was $0.00.

Yes, I know I could have used a hose and input to the mechanical fuel fuel pump but this coach does not have an operational one and the steel line
back towards the tanks is damaged.

Yes, I also know about the possibility of fire so I have 3 fire extinguishers (2 AR-AFFF and 1 CO2) within 2 feet of the open hatch plus 2 more
outside with the fender liners removed.

I just want to know what other people have done.

Well, unless the carb started off DRY 19 years ago, it probably is going to spew fuel and not mix it well if at all if it doesn't spew from a stuck
float. I would grab a functioning carb off the shelf or K-ball one from a working machine and use that to move the coach because it's likely you will
have to take the existing one off or apart anyway. Such a simple swap probably takes less time that the fuel hookup and opens up the possibility of
using a carb with a different fuel connection. It's all temporary anyway, and would be a lot safer with a carb you know works.

That does not solve my problem. The fuel tanks and lines have not been cleaned yet so a temporary source of fuel is still necessary for what ever
carb I use. I have already removed and inspected the carb for deposits and etc. So I will be reusing it until I determine if a more extensive
rebuild is necessary.

All I was asking about is what fitting on the front of the carb are people using to clear the thermostat housing and possibly where do they get it.

I have not tried the one I had made yet as I still have several vacuum hoses to replace and have to reinstall the plugs.

Ken,

15 or 20 years ago I was visiting a friend who ran a marina. He had a stack
of boat gas tanks that were replaced on a recall. He said there
was nothing wrong with them, so I mooched one. Holds over six gallons. Has
a quick coupler, so I attached a filter and a low pressure
fuel pump and a length of hose. I used a fairly long cord for power with
alligator clips to connect to the battery or whatever. I also have
a short piece of 3/8" tube from the junkyard for the carb if needed. I have
gotten a lot of use in many applications.

Thanks Gary. That is what I was looking for. What people have done. I have access to a boat tank but the one I'm using is only 1 gallon probably
off of a lawn mower or snow blower, and much easier to work with. I like the shut off valve on the bottom of it too.

If I get it to the point of driving it any distance off of the airport then I'll get the mechanical pump going and put a 5 gallon tank on the front
bumper. Cleaning the main tanks is a spring project. Too cold now to be laying on the ground and doing that stuff.

Thanks again

Ken

Ken, I did not reinstall the filter can, but instead used an adapter from
the large filter-can threads to an AN-6 flare. Then, I used a hose with a
right-angle AN-6 flare fitting. I have an inline filter in an AN-6 metal
body in the aircraft hose just upstream from that point. The hoses are
rated at high enough temperature for that application.

Rick "or you could buy a metal line for a mechanical fuel pump from JimK
and cut off the flare and bend at the carb end, etc." Denney
