when Tracy asks me why I'm using check valves,
maybe I'm missing a big point [not again!]. I thought it was std practice
to run redundant electric fuel pumps in parallel. I was going to use check
valves to keep the flow going the right direction. some facet pumps have
built-in check valves,[40148] but I have yet to locate anyone who sells
them. I am using a Weber carb, so only need low-pressure pumps. I
had actually bought a "red pump" like Lynn suggested, but two of them weigh like
10 lbs. I was hoping 2 facet cube pumps would work for me. a bosch
68758 also may work, but I can't find all the specs for it.[pressure?,
volume?]
so is the redundancy
overkill?
