That system is called a pressure system and while not cheap parts are available and they work well.The motor can be adapted to use a standard OMC diaphram pump I believe it has been discussed here and you may be able to find it using you edit button at the top of your page.
Do search using key words.Most likely your pump
simply doesn`t have the beef to push it into the carb.You may want to get a service manual and check the pump system set up.Sometimes you can find them at the library.
