Fuel Pump
Question, the 289-302-351W fuel pumps are basically on the same application wise. But was there any difference between carburation? Like did they have a different one for 4V equipped engines?
Something I started thinking about last night in bed wondering if there was a difference. I honestly don't believe there is since there isn't in the timing cover housing between engines.
Im inclined to believe that the same fuel pump was used on any 289-302-351W be it 2V or 4V equipped. But want to make sure first.

Now if you find there is no such thing and the stock pump just cant keep up, I don't really see this happening, you can go with a USA made pump that will.
Welcome to RobbMc Performance Products
I am not using his fuel pump but do have 2 of his starters. If you have headers in any thing and is a PITA to get the large stock starter in/out you will not have that issue with his.

In terms of flow and pressure they are all the same. Actual physical dimensions in terms of mounting and pump arm operation are identical. The only differences will be fitting location orientation and number.

I will check into it a bit more later today. Im having to do a few other things to get ordered first for this weekend.
But I have a '78 351W but its a 2V and it has the same fuel pump as my '82 302 has. But I will hit up like rock auto or maybe I will check out my ford parts and illustration guide and see the fuel pump section and see if it shows the same part number between 2V and 4V.

well looking at the parts and illustration guide real quick this is what I see.
E3TZ-9350-E and its listed as fitting 80/87 255 to 351W.
E5TZ-9350-D and this only listing is for 85/87 E/F250-350 351W over 8400# GVW.
Those are the only two pumps for 289-302-351W small block engines listed. So I assume they are the same fuel pump reguardless of 2V or 4V but I do want to do some digging on the E5TZ-9350-D as being a E/F250-350 with a 351W it might be a 4V optioned engine.

Well then it looks like I can just reuse my old fuel pump and be fine then. Was doing some thinking Friday at work and was thinking if I needed to upgrade the fuel pump. But im not running a 4V bigger than Ford ever ran.

The stock mech fuel pump will support carbs up to 1000 CFM once start nearing that mark then an upgrade may be needed. So no you do not need to upgrade the pump.

I'm running a stock mechanical pump with my 600 CFM Holley, and it works fine. Besides the block, crank, and rods, the fuel pump was one of the only other items I re-used in my rebuild. When I bought the truck last year, it had a brand new pump on it, so I figured I might as well re-use it. I'm certain it's just one of the cheapo ones from Napa or the like.
