Went down to NAPA to pick up a fuel filter for my '77 Bronco, went home to install it can't figure out where it is? Either I have the wrong filter or previous owner took it out. I installed a Wix see through filter before it goes into the carburetor. Here are pictures of the carburetor, please make sure I have the right fuel filter and please locate where it goes please. Thanks!

screws into the base of the carb where the fuel hose attaches to it.

Should I go ahead and install to it? Since I already have the Wix in line see through filter do I really need it or would I be double protecting myself or restricting fuel flow? Should I put some teflon or gasket stuff around the threads before I install it? I'm working on why my Bronco is cutting out while I accelerate, figured I'd start with the fuel filter and do a process of elimination. Thanks!

I'd install it since you already bought it. One more thing you KNOW is good.

I would use the teflon tape myself. Might not be necessary but......

Avoid the teflon tape. It tends to string out and the strings will mess with the carb (needle and seat, jets, air bleeds, etc.)
The trouble is the teflon does NOT disolve, so you will never get rid of it. Better choice is a very light coating of teflon paste.

If it were me I would also use the see through clear filter.

Yes, the filter would be redundant (which isn't a bad thing since it is so cheap) but you get the added benefit of being able see if you are getting fuel up to the carb.

These things are notorious for vapor locking which is when the fuel gets so hot it starts to boil / vaporize causing the engine to starve for gas.

The filter you bought screws into the front of the carb where someone has threaded in a barbed nipple. Actually, I prefer to replace the little screw-in filter with an in-line filter using that barbed nipple as in your second photo. No, doubling up filters isn't a good idea. It makes trouble shooting difficult. Just carry the spare in your tool bag.

This is what I ended up doing. Next time I'll eliminate the fuel filter that goes right into the carburetor. Well that didn't fix the engine cutting out while accelerating problem. The problem still persist, so the fix continues.

Mine didn't have a filter on it when I bought it. I just recently had to replace the fuel pump so I went ahead and installed a filter

Don't eliminate the factory filter.

Did you check to see if there's another added one somewhere between the tank and the pump? Maybe near the valve?

Try to describe your hesitation better.

That's a pretty dirty and neglected looking carb.
Could be the accelerator pump or power valve.

I would say don't bother with it i saw that you have an inline filter before the carb anyway. So stick with that and take the other back. those screw ins have a bad habit of stripping or breaking off in the carb and then you are in a hot mess. so it is not necessary.

The stock 302 engine with stock carburetor idles fine but when I accelerate the engine slightly cuts in and out. It smooths out when I hit about 45 mph and up. Figure I'd start out with the obvious and start the eliminating process. Where is the accelerator pump or power valve. What can I do to clean up that carburetor? I know it looks dirty but not that dirty when I take the air cleaner out and look into the carburetor. Thanks!
