ok you guys figured out my voltage regulator problem now lets see if u can figure out this one! i have a F-250 with a 7.5L year 84 to be exact i just rebuilt the carberator on it and while i was taking it off i broke two of the steel rusted hoses which both go into the engine. so i got the carb back on and now i have to figure how to get these two hoses fixed.

I took the plate off which had the hoses that came out of it. i relized that the two hoses were just a loop of gas that comes out of the carb runs around in the engine and goes back into the carb. I think it has something to do with heating the fuel. which ive never heard of b4 but i think it has something to do with being more efficient. I can't find this part would any of you know where i could something as rare as this? Ive tried everywhere rockauto.com, napa, motorcraft, carquest etc... but noone knows what im talking about.

Do any of you guys think it would be a problem just to attach the two hoses coming out of the carb together and just forget about it running through the engine or do you think it would run bad? i know if its in there ther must be a reason for it!

Thanks

Do you have dual tanks? I have a 86 F250 with 2 into 1 gas lines one for each tank then they merge into 1 line going to the carb.Do you havea fuel pump on your engine? Mine has the fuel pumps inside each gas tank.

 

Are you sure they aren't smog lines of some sort? The only place the fuel lines should enter the motor would be if you have a mechanical fuel pump. I know on my truck, 85 F-250 with a 460. I have 2 fuel lines that run up the side of the motor, and then join into 1 line just before the carb. One line is for supply and the other for return. If they are truly just fuel lines, you could just replace the broken part with some rubber line for now, or you could get creative and buy a cheap tube bender and some metal tube.

 

460's had an option called HOT FUEL. maybe it has something to do with that.

 

sounds like the heated air intake and clean air tube for the choke to me. Do these just go into the manifold to the left of the carb (standing in front of the truck) ? If this is what it is just make some new tubes out of brake line with the correct fittings its just a type of choke stove for the auto. choke and basiclly pulls clean air from under the air cleaner runs it through a hollow area in intake manifold above the exhaust crossover into the choke housing to heat the thermostatic coil in the choke to help open your choke

.scroll down to the VERY BOTTOM and tell me if you see these hoses illutsrated.

 

the images on autozone didn't help much since it was a 460 and they didnt have that engine listed. All i know is that it has something to do with heating either the gas or air i dunno why but all i know is that i need to fix it and the problem with fixing it is the metal tubes coming off the plate and connecting to the carb broke so i might just have to solder them back together or sometihgn i think that what im gonna end up doin. I was just wondering if anyone knew where i could get such a thing.

adn yes plow pusher they go into the manifold just to the left of the carb i know that they have something to do with heating and when i broke them i know no gas came out.

 

where do they hookup on the carb? Need some specific information

 

on the left side near the top. i just rebuilt it i think they come out above the automatic choke. but its too dark outside to go check now so ill have to letcha know in the morning for sure.

 

The basic principle of these engines is to have the Fuel COLD... not hot.

I am aware of a quick heat up of the engine by running coolant through a Carb Plate that is mounted under the carb though.

But you said the hoses were a loop of gasoline

Quote:I took the plate off which had the hoses that came out of it. i relized that the two hoses were just a loop of gas that comes out of the carb runs around in the engine and goes back into the carb.

That to me is part of an Emissions system.

I also thought the Un-used (or overload) fuel was sent back to the fuel tank.

 

i thought that they were what carried the gas to heat the gas. My dad though so and so did the mechanic that looked at it but i still dont really care what it does i just wanna find somewhere that would sell such a crazy part lik this and then ill be on my way otherwise i might be just soldiring the old metal hoese back on. I did have the carb apart and didn't think to look at it you might be right though they could be for heating the choke up. My dad though it might be gas because he though that if u heat up gas the engine will run more efficient and when you have a 460 you need it as efficient as you can get it!

Plowpusher's response is totally correct. The tube(s) supplies heated air for the choke. On these 460's the electric portion of the choke is an "assist" to get the choke "off" quicker but, the primary choke operation is controlled by the heated air from the intake manifold tube(s). On my truck, both metal tubes rusted through right at the mounting plate. I removed the whole assembly (I think I had to remove the carburetor to get it out), cut away about 1/2" of the (rusted portion) tubes and brazed them back on--works great. P.S. Local dealer's parts department said "obselete, no longer available".

 

Motormite makes a Universal choke Tube kit. It's located in the HELP section of most auto stores. They have the fittings and everything you need.

 

I agree about the choke housing warm air hose BUT
we were given this.

"Terminology is everything"

I have never seen a "loop of gas" hose

Perhaps an illustration of all the hoses connected on an engine will help.

I have all the emission diagrams..can you post the info from the white valve cover label for engine Ident ?
