Remove marine bulb style hand pump?

Installed the auxillary fuel pump and it works greats. My question: I also have a marine style bulb hand pump installed, when I bypassed the stock hand primer pump last year. Should I remove it? Can it handle the pressure the auxillary pump produces? The bulb pump seems pretty plump but it's holding, no leaks. Will it eventually burst or can I just leave it alone for now? I'm planning on a 700 mile road trip next weekend and would like to wait to replace it if I can. I've ran about 150 miles since I've installed the auxillary fuel pump and no problems. Thanks, Keith
