No output specs on the AC pump but the original equipped Carters were 3 1/2 to 5 psi. Quantity was 1 qt in 60 seconds at 500RPM.

I used a rather "earthly" attempt previously. I disconnected the hose at the bowl and cranked the car quite a bit, while watching the hose from beneath the hood while I cranked. I could see from the driver's seat while cranking. Nothing.

So, maybe it is a volume issue.

Do you guys agree that the only two things remaining are the hose to the bowl and the pump, itself?

As far as the eccentric, the picture I took is probably the best look I'll ever get of it, so I don't know that comparing to anything will help.

I need a new signature:

"Learning how cars run, one component at a time."

If you cranked the engine with the outlet hose open and nothing came out, the usual suspects are:

-bad pump
-bad inlet suction hose
-air leak in the steel fuel line to the tank
-broken or clogged suction line in the tank.

OK. The Airtex 3450 is looking pretty good about now.

I notice that one of the ports is shown to be at about the 11 O'clock position. My outlet port is there. This is where the steel hose connects.

I can't tell where the second port is on the AT 3450. But my inlet hose is rubber, so if needed I could easily reposition or replace it.

Here is the link to the picture:

Can you tell from it that the port shown is, in fact, the outlet? I am merely wanting to avoid having to re-do metal hosing.

You can see my existing get-up 2 pages back where I submitted a photo of it.

Thanks for all your patience and assistance. I am just trying to insure an easy job so I can be done with it. I don't know what a re-build costs, but for $60, new is fine with me.

I had to work on some other things the past few days and am getting back to this. I am getting the Bosch pump and will post results. $18.30.

I, for one will be watching & waiting. If it's the NAPA pump, you might want to ask them how old it is and how does it react to alcohol. Hopefully better than their carb kits.

It turns out NAPA says the pump is not available, either at its warehouse or through the mfg. So, I ordered the Airtex 3450.

Very interesting. I wonder if they are picking up on the fact that selling pre-E-10 fuel components is leading to unhappy customers.

Here's the Summit link to the DUAL action 56 T'bird fuel pump.

Whats da word???, Thunderbird. What's da price???? forty-fo twiced.

THose of us with vaccuum wipers mite want to consider the Summit dual action. I would be most likely to assume that since it's Summit it will be modern fuel friendly.

I now have the Airtex pump and am wondering which of the 2 ports is the inlet and which is the outlet. If I had to guess, I'd say the one at 11:00 is the inlet, and the one at 12:00 is the outlet. I'd like to be sure, though.
