fuel filter with return line - what oem application

I know mid 60's Pontiacs with AC had them. Restoration repos are available @ $35.00 (Not)

Amc's had them but the return line comes out the top and not going to work so good.

Any other manufacturer use them?
Got an application or part # for them ?

 

i think a fuel filter from a jeep around 1985 or so has a 3/8 inlet and outlet and a 5/16 return.

 

Thanks for the pic that's the type for those that don't know.

Yep, that's an amc jeep and the return is on the carb side or up.

 

Years ago I picked up a '69 Kingswood wagon with a BBC and AC. It had a 3 port filter for inverted flare threads, can't remember what size though. Might give it a try.

Bump for the night crew input

 

Drunk man beat me to it. Basically any dodge pickup with a 318 or 360 carbureted will have it like that.

 

My 88 Wranger has that type. The #s are:

Wix -- 33040
Delco -- GF423
Motorcraft -- FG13

 

73 plymouth Cuda 340 should have a metal inline filter with a return port.

 

At least two were used in the Chevrolet line up:
AC# GF99 -

Corvair turbocharged: late 63 - 66
​

AC# GF432 -

Big Block full-sized: 67 - 69
Big Block Corvette: 68 - 69
Big Block Chevelle: 69
Big Block and 350 Nova: 69 -70
​

The difference between them is the GF432 main fuel line fittings are flare tube and the GF99 pipe.

 

Ditto, 60's Poncho w/ factory a/c. The idea was to prevent vapor lock, by allowing the vapor to be vented back to the tank. My 64 Bonneville had one.

Ps; The filters were mounted vertical, with the "double" side up.

Really?
Crap

 

Mine in the Wrangler is mounted horizontal. You just have to make sure that the return line is at 12 o'clock and it works just fine.

 

Ford trucks with 460's came with what Ford called the "hot fuel option" it uses a return line from the filter also. I can tell you that I run this set up on my 460's, sure stops vapor lock. I have never worried about clocking the return line.

 

Might not be what you're looking for but 409's had a sediment bowl type filter with a return line on it.

 

I have a return line on the carb goin on a Y fitting b4 the fuel filter. On a 70 Ford.
Always wondered what its for, as i ran it without for some time and seemed to make no diffrence whatsoever.

 

Thanks guys!

 

Why is the return line on the carb side a problem? AMC did it that way so fuel on the higher pressure side (a little higher before going through filter) wouldn't return to carb "early". There was no control valve -- fuel returned if it "dead headed" at the carb.

 

No major issues, aesthetics mostly minor routing ass ache

 

Well, there might be a problem with too much returning with the return on the "in" side, especially if the filter starts to get clogged.

 

My 1983 Dodge van with 318 engine has the return line fuel filter.

 

Yep,
i was thinking it would be made similar to the late model units but this is much simpler
