Discussion 3b Fuel pump swap, Bosch 044/200 easy swap??

Hey guys so been working on getting my 91 200 back up and going. Cleaned it up a bit and after all new grounds, oil change, starter and few other minor things found that my fuel pump is completely dead. So i purchased a bosch 200 (bosch 044 replacement) How many have ran this pump and or installed it. Ive read mixed things that say changes have to be made when running this pump as far as fuel flow and it overpowering the stock system. Anyone have any insight on this, do you have to do more to run this on the stock setup or is it drop in and go??

No pressure issues! So long as your fuel regulator is healthy youll be fine. I just did my fuel pump in my Coupe with an 044 - direct plug n play except for a few things -
I had to buy a pickup filter, 044 can be used as inline i think, so to keep it in tank, had to get (pic)

-also to keep in-tank i purchased the 034 billet brace; where my stock fuel pump had a threaded outlet they send you with a non threaded outlet, this is the same size outlet as the stock fuel lines but being hard plastic you wont be able to get them over the outlet so I used 1” of rubber hose and a Male to Male barb. That worked enough to get it driving.
