Has anyone fitted one of those non peanut style late model sportster tanks on a dyna frame (street bob 2007) 

Thinking more this look

Fuzzy pic but to me it looks like a stock tank on a Shovel FXE.

I fitted that same tank to my Dyna carb model , I had a few old shovel FXE kick start only model. They are not a Sportster tank most are Shovel big twin tank, but they did haves roadster ( sportster ) model that used one, just the sportster that used that tank had the peacock on right side shovel big twin had it on left side.  Could use external electric fuel pump, the tank not hard to fit to a dyna , just all made for carb

Big problem with the dyna is the back bone of the frame is a horrible looking big square tube with a ton of wiring along it, the tanks cover a lot of nasties.

Early 70's Superglides and Fat Bobs used this tank, from memory they held 3.3 litres, same as a king Sportster tank. They're not easy to find.

Mr Mow I fitted a shovel super glide kick start model [small battery model ] shovel tank to a twin cam dyna carb model no problem as that tank has a big wide tunnel for frime clearance

Thanks for then replies. I think I will go on a hunt for an old superglide tank and external fuel pump.

what state are you in? 

In line 12v fuel pumps are usually available from speed shops, try and get a small variable unit with a range at least between 55/62 psi (I think). Don’t wire it through the ignition switch but via the exiting wiring to the fuel pump thus keeping the EFI fuel cutoff relay intact.
