Fuel Pump upgrades??

[1990m3]

My car intermittently won't start at this point. Seems to start fine when cold, but not always when warm. Fuel pump works intermittently I think so I am pondering the idea of a new fuel pump.

Do any other e30's have larger capacity fuel pumps than the one in my '91 318is? Should I just get the same one or should I go for a fuel pump from an m3 or 325? Haven't had a chance to cross reference the part #'s yet, but I just want to make sure I don't spend the money on a new pump when it turns out there may be a better alternative out there.

Thanks

i'd like to know this too. my pump died not so long ago (about a month after the s50 swap) and i replaced with bosch unit for a regular e30m20

stock pump is fine. no need for anything else. i'd just get a new replacement

I'm trying to save $75 buck here...anyone know if the other e30 fuel pumps will work? I might pull the one out of my m3 tonight and check it out. Hmmmmm

i replaced the pass side pump with a unit from a 1990 325is and it worked fine. i have a 1991 318is.
