fuel line question

I'm sure I'll feel stupid when I get the answer but what is the gold colored part between the fuel line and the carb? I found I was dripping fuel there last night so I took both parts off, carefully reassembled them and when I started it up, it was spraying gas. Obviously one or both of these parts needs replaced/upgraded. Just need some input to do it properly.

Looks like your fuel filter and it looks like your line is cross threaded causing your leak

So you can either get a new fuel line and filter or get one of the older type filters that have a nipple on the end and cut the nut off the line and connect the line and filter with a piece of hose

I just bent up a new line using my original as a template. I added a barb and a small piece of hose at the end to make fuel filter replacement easier. The small filters at the carb are notorious for plugging up without notice so carrying a spare is a good idea.

If you ask for a fuel filter for a late 70's Ford it will have a nipple on the end where yours is threaded

Yo R,
Consider adding a flare nut wrench set to your toolbox.
Use it on brake line fittings too.


As suggested; Sone parts stores carry this carburetor fuel line inlet with barbs for the fuel rated hose. Can add filter here.

See my partially recovered Bronco web site ...Will need to clean up dead links & add many more new links some day. Thanks to Mr. Schwim!
THANKS to ALL WHO SERVE!

I wound up buying a filter for a '77 which has the nipple for the fuel line, and I spliced in a small section of rubber tube. It looked good in the driveway, drove it about 30 miinutes and checked again. Dripping fuel again. I tightened everything up and it held at idle again. I'll know today if I got it or not. Planning on getting a new carb, hopefully soon. Thanks for the help everyone.

Yo,
Does the carb have this Brass Fuel Inlet Fittingthat scews into the body & the line screws into its other end?

CUD4755 - Carburetors Unlimited

Most never use Teflon® tape on the fitting due to possible break-down of the tape and entry into jets/orifices. Apply some thread sealant to the threads - such as Permatex® High Performance Thread Sealant.

I'll have to look again but I don't remember seeing a fitting. I think it screws straight into the carb. Yeah I knew not to use the thread tape but if it's got a drip, I need to use something until I can replace everything. It's my daily driver and my budget just doesn't allow me to replace everything right now. Especially with me working on the suspension/steering and needing new tires.

Just think, if it leaks fuel and starts a fire, you won't have to worry about working on the suspension. FIX THE FUEL LEAK PROPERLY, not a place to go cheap.

Yo racerx72,
Try a self taping over-sized inlet fitting by Dorman.

Dorman HELP! Online - Search
Sample pic.


The gasoline resistant thread sealant comes in different sizes, from about $6.00 & up at most parts stores.
I believe some storehave even smaller tubes for a time use.

Did mine with a piece of 5/16 off the pump in steel, then on the other end a flare to barb fitting with a small piece of high pressure injection hose to the filter. I used high pressure clamps to hold the rubber line, overkill yes but I do not have to worry about leaks.


I also used a little teflon tape on the threads for the filter, just on the outside as to not let any buggers get into the carb seat.

Thumbs up

Got it all sealed and tightened up and no leaks yesterday. I'll check again tonight to be sure. Thanks for all the help everyone!
