Default Engine swap : `91 EFI into `83 F150

Good morning community!
Need a little help & advice: My stepson is going to buy a `83 F150 as a `kit`,
this Truck had the 300 cui straight six and the now-owner started implanting a 351 from a `91 BRONCO donor car, as well as interior parts like dash, instrument cluster and I think other interior parts, too.....
Now my question an doubts: As far as I know, the `83 has a mechanical fuel pump other than this EFI 351, which runs with an electric in-tank unit,now, how hard is it to install the tank from the Bronco under the truck`s bed and wire up the fuel pump harness, as well as the ECU harness to get this thing running???
Will the `91 dash just slip in on the existing `83 dash brackets or do we have to custom tailor anything e.g. the windshield bend..?
Reason I`m asking is: The whole combo is about 250 mls from us and I don`t want to go there just for wasting time, next thing, we`re here in Germany, so missing parts that are not easy to get from any of the known vendors are quite impossible to get, since Chevys and Dodges are way more common over here, don`t ask me why!
Anybody who knows anything please let me know everything so we will not run into a lot of trouble ending up with a huge mess....
Any help greatly appreciated!!!

Thanks a lot in advance and have a nice weekend eveybody!

F150/Bronco went through a major body style change in '87. Many F150's had dual tanks....... Don't think Bronco ever had dual tanks?

I would go to online sites such as:

Look up the same parts for both '91 and '83 and see if the part numbers, dimensions or whatever info they give, match.
Also you can look at web sites for auto-parts stores such as Napa, Autozone etc.
1986 F150 XL - Short Bed - 5.0 (302) EFI - AOD - 4x4 - 31x10.5x15 - ARB Air Locker - Flowmaster dual out
(OBD1 code reading and fuel system info)
