    Vapor Return lines

    All my stock factory 440 GTXs with automatics came with the separator, in '68, '69, and '70. This includes both the two A/C and three non A/C cars. The base 440 for station wagons, Imperials, and the Chrysler New Yorker was a different animal. I never had a vapor lock problem with my stock '66...

    Removing Fuel Pump on GTX

    What I've done, is bump the starter, and check the position. When it's at the innermost position, you will be able to move your fingers around in the access area. If you are working alone, the grease is essential to getting the darn thing to stay in place. If dry, it will try to fall out...

    Removing Fuel Pump on GTX

    If you have access to a lift, it's easier to get the pump in and out of a Hemi GTX from the bottom. A bit less wiggle room in these than the 440 cars. Changed the pump in mine without removing the alternator, but no way would that have happened working from above. Previous advice on push rod...

    Correct fuel pump for ‘68 Coronet R/T?

    I used the Mega Parts separator for my two installs. The pieces I ordered had the correct restriction on the return outlet. Good point to check though, don't want a surprise if vendor starts procuring the part from another source. I think a lot of cars lost their originals when OEM parts...

    Correct fuel pump for ‘68 Coronet R/T?

    I've got a reference book (Charger, RR, & Super Bee Restoration Guide, by Paul Herd, 1994) says the 68-69 HP 440s all got the vapor separator and return line, the lower performance 440s (station wagon, base New Yorker) didn't. This seems consistent with the fact the HP versions got other...

    Correct fuel pump for ‘68 Coronet R/T?

    Baby Blue, my unrestored '68 GTX, 440 automatic, came new with a vapor separator and return line. Car was a December Lynch Road build. My stock numbers matching Hemi GTX was restored with the return line, but no vapor separator, same with my fifth GTX, a '69 numbers matching 440, late build...

    Carter M4845 fuel pump.

    I had a similar situation with a pump for my Hemi GTX two years ago. It looked correct, but the fuel outlet was also not right. I got lucky, the owner of the shop that was doing the install and I worked together to cobble up some NAPA parts store fittings to make it work, but there was no way...

    Vapor lock 440 6-pack issue

    When I owned Baby Blue, the car was set up with all the features you described, and started like modern day fuel injection under all conditions with modern day fuel. Car still had the factory vapor separator hooked up, carb spacer, insulated fuel lines away from exhaust, 40 year old Holley...

    Lead gas additive

    Baby Blue (my never restored, never overhauled former '68 GTX) ran 68,000 miles on leaded premium back in the day, then switched to Amoco 93 octane unleaded pump gas in 1974 when my friend Bob acquired her. I did the same, later switching to other brands as unleaded became the mainstream fuel...

    Vapor lock 440 6-pack issue

    I went through the same thing with my last two stock GTXs, a 440 4bbl, and my Hemi. The return line was in place, hooking up a factory style separator cured the problem.

    A Closer Look at the Carb Setup with Questions

    My '68 GTX with the original Hemi and carbs was set up by a previous owner who rebuilt Hemi carbs professionally, Dick Katter, in Woodbridge, Va. He bypassed the port on the back of the manifold as well, and replaced the factory choke with a manual valve. He owned the car for 31 years, and...

    I need some carb therapy... 69 GTX

    My experience with my former '68 GTX, Baby Blue, may help, or just stir the pot. This car was pretty unique, in that it was almost completely stock, numbers matching, with the exception of the carb and fuel pump, from back in the 1970s. I owned it twice, 1983-91, and again 2013 until last...

    Vapor Lock Remedy/ Advice

    Chrysler introduced the vapor separator can and return line on the the '68 440 hipo engines and the hemi. Never had a problem with my first three stock GTXs. The last two had the can removed, and the return line blocked off. Both had vapor lock problems. Hooked up a can and reconnected the...

    Looking for advice

    Good point about the check valve. Had the same problem as the OP with my 440 Track Pak GTX with original Carter AVS when I first got it, new stock Carter fuel pump installed, and from then on, started just like your Superbird. Ran it on pump gas for four years until I sold it last spring. I...

    Vapor Lock Remedy/ Advice

    I use the Lucas anti-ethanol stuff plus Stabil. Don't know if it works, but like you, I haven't had any problems.

    Vapor Lock Remedy/ Advice

    Another thought, trying to keep things simple, how old is the current fuel pump in your car? The ethanol may have messed it up. I installed new fuel pump when i did the vapor separator, i was concerned high ethanol gas car had used in Iowa had compromised it. Problem solved, but i can’t say for...

    Vapor Lock Remedy/ Advice

    Baby Blue has the spacer, electric fuel pump, factory vapor separator, insulation around all fuel lines within a foot of the engine block, but still has the the intake manifold hot spot. Car starts as reliably as my Lexus in hot weather. Modern gas has not been an issue, no question in my mind...

    Vapor Lock Remedy/ Advice

    I had (have) the same problem with stock GTXs that had the factory vapor separator removed, and the return line plugged off. This became common when the supply of factory vapor separators dried up. I kept an inventory of NOS separators from back in the day. Put a separator back in the the Track...

    Carter AVS Four Barrel casting numbers

    I've tried to have my cake and eat it too. I have a date code correct NOS Carter AVS, that I carry in the trunk of my '68 GTX when I show it. I run the car with a Holley Street Avenger, which drives better than the original Carter did.
