the facet pumps may last 25 days.The airtex type solenoid pumps last longer,I bought my 12psi from NAPA made for diesel,they last a year.FASS used to make a veggie pump,and they sell rebuild kits,but they are over $500.I used larger fuel line coming from veggie tank to heat exchanger,I also bout injector fuel line heaters,and wired a thermo on it,so it would turn off when coolant was hot.
