alternative to fuel vapor separator

[myk]

Your pump has a screw-on fitting?  Gah!  Why do they keep selling/showing me something different?  Anyway, looking at my ultra-cramped Camaro's engine compartment gave me an idea that is ugly but will keep the kinks out: I am going to try routing the vapor separator and line along under the motor, then inner-fender and then up and over to the 'carb.

I'm gonna' feel really stupid if I find that my high speed surging was caused by that kinked fuel line and not the pump, 'carb, ignition and everything else I've been messing with over the past week...

Here's a big ol' bump for you. Just stumbled across this thread.

The vapor outlet has an oriface in it.

Anyway, yes there is a much cheaper alternative. There is a WIX/Napa filter available that will work. Unfortunately, I'll have to do some digging to find the p/n.

It does not look like the factory one though. It does not have a mounting bracket. It is bare metal. Also, the vapor port is on the outlet (top) end, opposite the originals/repops.

VERY interesting thread... din't know about this. THANKS! Now I see this, I think a buddy of mine got a problem with vapors and gas didn't arrived to carb so engine just died continuouslly!

Son of a Bitch!  I don't think I even have that on my car, I'll have to check!  Funny how many "mechanics" don't check these small things!

You know, it's a funny thing.  I was readying over the shop manual last night and read about the vapor separator.  In the first paragraph, is says it's used on the 440 hp and 426 motors.  Does this mean it's not required in a build, as my car isn't a HP?  Just a 440...

this fuel separator was the key to a problem i had when racing a sixpak superbee years ago.....everything went well during the quarter mile, til about 3/4's way down the 1320 the motor would starve for gas....turned out that i was using a regular two legged str8 thru filter....once i changed and put in the proper piece, the three legged separator, it solved the problem. consistant 12.0's.

I know this is a very old thread but I had a question on this post. I have been having vapor lock problems everytime I drive the car and went to napa today and purchased the #3054 vapor seperator above. My question is where is the 1/4 vapor line suppose to go out too?

[471_Magnum]

Connects to the return line. Only 440 and hemi cars were equipped with the return line.

[MoparMotel]

With my car being a 383 that explains why I couldn't find the return line 

Thank you

[471_Magnum]

I'd be looking other places for your vapor lock issue.

Is your filter before or after the pump? Should be after.

Do you have an insulator under the carb? 5/16" insulator is pretty much a necessity.

[MoparMotel]

Filter is after the pump- no insulator just doubled up on gaskets when installing carb.

So although I have the 440 and the rest of the drivetrain out of a squad car, I don't know if I have a return line.  Where is it and how do I recognize it?

[y3chargerrt]

It runs on the frame rail right next to the fuel line.

It runs on the frame rail right next to the fuel line.

I'll have to crawl under the car and see if I have a return line.  If not I can imagine it's not that hard to add?

Thanks Ron!

Awww nuts, guess I don't have one of them seperator thingymajigs....

Man...where's all this oil coming from??
