In tank fuel injection pump domensions.

[blubuckaroo]

I'm planning on using an in tank fuel injection pump for my project.
I can't find the dimension of the pump assembly that protrudes above the tank from any of the manufacturers.
From where I stand, this is the most important dimension to be sure the assembly will fit.
Am I missing something here??:?

I would think if you are modding a tank you would actually want the pump and connections in hand.

More precisely, the parts change over time so whatever measurement someone gives you might not be what you need tomorrow.

So if you havent call the manufacturer and ask.

And in case it's something that someone here already has in-hand and can provide dimensions, you need to specify which one you are intending to use. They're all quite different between the ones that are retrofits for original tanks, or if they're part of a kit for an aftermarket tank.

In the case of the retrofit, some of them are quite tall. In the case of the aftermarket tanks, most of them are super low-profile at the flange, but the different ones could have the feed and return and vent pipes sticking up at different heights. Aero is one that has a thin metal flange, but with tubes that stick up about 1.5" or so.
And some tanks are recessed in that area for just the clearance issues you're speaking of.
If it's a factory retrofit, you'll need to state the brand. Like the difference between an Aeromotive and a Holley, or Tanks Inc. vs someone else's.

This for the Bronco, or the Falcon (or whatever your other project is)?

All good points. I should have the pump in hand before pulling the trigger and having a tank fabricated.
I'm drawing up a custom tank for my Ranchero project, but the same issue would come up with a Bronco application. The in-tank pumps drop in from the top, and have sort of a hub assembly with connections that sits above the tank, right against the Bronco's floor.

Cool. Since you're having a tank fabricated for the application, you might be able to make the top of the tank where the unit would fit slightly recessed to keep the goodies off of the bottom of the vehicle.
Kills two birds too. More clearance for the electric and tubing bits, and adds the air space for expansion and resistance to over-filling that a lot of tanks lack.

As long as it does not cut too deeply into the gas space and cuts your capacity down too far, that might be the way to go no matter what other aspects are being taken into account. How big of a tank can you fit in there? Seems like my buddy's '64 (or whatever year it is) has a pretty good sized tank in his.

It looks like a good place for both the tank and battery. That way the spare tire can go under the bed where it belonged all along. The big obstacle is there is a driveline tunnel right in the middle where the tank will go. My plan is for a tank that will cross the tunnel but be shallower on the passenger side. It will hold 13-14 gallons.

I used an off the shelf Chevrolet in tank pump assembly and I had to cut it down short by about 2 inches. Kind of a pain, but not too bad.

i have the in tank returnless pump, i got if from rock auto for a decent price. I have an aero tank with a recess in the top to accommodate the pump.
