Volvo B18 - B20 - B30 - 544 - 122s - 140's - P1800 Swedish Mechanical Fuel Pump 1963

My Peirburg stamped steel mechanical fuel pump on my 1963 544 developed a big fuel leak from the bottom after sitting not cranked for about 3 months.

I have temporarily installed an electric fuel pump next to the mechanical fuel pump and it runs fine.

I prefer the mechanical fuel pump. Many vendors don't list as fitting the 544, but do list for the 122 and 1800. Being a B18 engine the pumps for the 122 and 1800 should fit ?

Has anyone had good service from the cast bodied pumps like this ?

Any particular brand ? There are many choices on eBay but maybe they are all made by one company ?

    I have no experience with the pumps you reference from eBay.
    They do look like ones I purchased decades ago which I believe were "Worldparts".
    However, that was before the proliferation of "Made in China" parts.

    When I did purchase these pumps that looked like the ones you posted, I had to install a fuel pressure regulator to get the pressure to the carbs. down to 2 psi.
    They were putting out 8 psi which is too much for the stock SU carbs.

    If you are using an electric pump, that's fine. But you should check the pressure it's putting out. SUs in a "factory" application don't really need more than 2-3 psi.
