Inline fuel filter install

Installed the Carter YF after having it professionally rebuilt. I also installed a new fuel line from the fuel pump to the carb, but knew not to fire it up without first installing an inline fuel filter. Question is where is the proper place to put it? Previously mine was just before the carb. Others have advised against that location and suggest putting it along the frame somewhere. I looked at the fuel line coming up to the fuel pump and thought putting it about 12 inches before the pump might work. What do you guys suggest?

Also, must I flare/double flare the cut ends of the fuel line or can I leave them straight?

Thanks!

I put mine coming right out of the tank. Used the short fuel lines hoses and clamps that came with filter (WIX 33022) and an adapter that screws into the tank outlet. Haven't had any problems to date. Note that I have one (Fram G3596) on my carb inlet also.

Same here

I have one under the tank at the rubber flex fuel hose, and I added one at the carb inlet when I was having a flooding issue

The one under the tank is just a barb fitting
The one at the carb is double inverted flare so I had to make a new line to the carb

You could place the filter where your picture shows, it just might be difficult to turn wrenches at the location and you might have to somehow valve your tank for filter changes depending on how your tank feeds, under tank/top feed

Dads50 advice is the right way, did this on his recommendation. This cleans the fuel coming out of the tank, and cleans it again just before it goes into the carb. This may be overkill, but it is a cheap way to eliminate trouble.

If you look at the beginning of Lonnies video he shows some docs showing of the durex filters being installed at the carb

Not sure why someone would advise you against that location

The tank filter protects the fuel pump from debris from the tank. I too run both filters. A picture is worth a thousand words and yes, it needs to be changed.

Okay, I took Dads50 advice and went to buy the WIX 33081 inline filter at Auto Zone. They cross referenced it to a Duralast brand they had in stock. Only problem I see is that the female end is too big for my fuel line to attach to, so I’ll have to go back to buy a brass adapter. Im also going to buy another adapter that has a barb end to put on the gas tank fuel petcock so I can attach another plastic filter there using a short piece of rubber fuel line.

BTW, are the metal filters reusable? This one was $5.99 plus tax.

Thanks for the help!

If you decide to use that filter you'll have to plumb it. Just get the correct male adapter for your size fuel line. You can see my adapter in the pic above.

Fuel filter should be changed during routine maintenance. The plastic clears ones are nice because you can see the debris in it.

At the carb or under tank ,or both is up to you. Important to add at least one due to the junk that get pumped into your tank at the gas station.

General Purpose
I recommend for any of our trucks:

Wix 33033 before the fuel pump. Just one is suffice. Use short hoses with hose clamps and abandon any petcocks/valves.

So......Hose from tank to fuel line on right side frame rail, fuel line down inside of frame rail to near pump (install 33033 inside frame rail with good access), slide fuel line flare nut back if pre-flared line is used, slip 33033 rubber hose on line, then 33033, then hose to pump inlet barb. Hard line from pump outlet to carb. Carry extra hose with you. Less leaks with hose clamps than a bunch of threaded fittings and petcock valves.

Those "can" type filters are not reuseable if you mean: do they have a cartridge. You do not want a replaceable cartridge type.

You do not have to flare the line for a hose. A flare does not do much to seal, it's not designed like a barbed fitting. It stretches the hose unnecessarily. If already flared, it's OK.

The goal for gas line is to reduce the number of connections/leak paths as much as possible. It's no place to obsess over originality. The engineers got it wrong back then with fuel lines and wiring. Albeit they only had the technology and understanding of the day.
