I'd like to know if they're the same as an AFB too.

The original AFB uses a smaller diameter pump than the AVS.

I've got spare plungers for the Eddy carbs. I'll have to measure the AVS to see if it's the same size bore. The AVS accelerator pump does not work. The passages are clear (aerosol test) and the plunger seems pliable. I think sitting for 12 years didn't do the carb any favors.

What about the ball check valve in the driver side bottom of the bowl and the one in the bottom of the pump ?

Edelbrock used to sell plungers separately. I bought a couple for some 500's I used to have.

Are the accelerator pumps for the new Thunder Series AVS the same as the old mopar AVS's? I've got a 4401S if it makes any difference.
So you need the pump for the 4401s? If so just buy the kit, they are available, usually needs to be ordered, from any good parts store.

I went through the same thing in my AVS. Sometimes you just don't get the shot. Really no reason for it. Worked fine most of the time.
I want my fair share

There are three different pumps,one for the AVS and two for the AFB.AVS is larger in diameter,AFB uses two different length pumps,AVS on right,AFB's on left.The AFB pumps have a check valve in the bottom of the pump,the AVS does not.If you have the correct pump,the pump length adjustment is correct,the connecting link is not installed backwards,the check valve in the driver side bowl to pump well is good,correct fuel level and the needle under the discharge nozzle is in place you should have no problem regardless of what pump you use if it is in good condition.I have been playing with these thing for 40 + years and can honestly say I have never had a pump problem if all the above are correct.I have went as far as soaking dried up leather pumps in oil and reusing them with no problems.

I know the Edelbrock rebuild kit(#1477) does NOT come with a new pump. It has to be purchased separately. O'Reilly auto parts has them in stock for $15. The new pumps are supposed to be ethanol compatible. I know it is different than the old edelbrock pumps I took out of 4 carbs. Just throwing this out for people wondering.

I put the Edelbrock pump into my AVS on my '69 GTX (from Bee1971 and superwrench's info in the linked thread ) but had to shorten it and drill a new hole for the wire clip. The Edelbrock pump was as long or tall as the one in the center in Bill's photo and the original AVS was shorter like the one on the right in the photo. Took just a little modification but it works......about 20 bucks from Summit or get the local Advance Auto Parts to match Summit's price, Advance's price was about $10 more.
