fp280z Posted September 9, 2005 Share Posted September 9, 2005 Anyone mount their Carter rotary fuel pump (4070) inverted? As in upside-down? I believe that the manufacturer advises against it but I think I've read some posts saying it was ok. Since my fuel cell hangs kind of low, the only way I could get good flow to the pump was to mount it upside-down. Otherwise, the bottom of it would have to be way too low. So, anyone do this with satisfactory results? What are the drawbacks? Reduced pump life? Pressure regulation issues? Safety issues? BTW, this is on an trailered autocross car that never sees the street so it has to be reliable but it's never run for long periods at a time. Thanks. -Rick http://www.io.com/~rickm/fp280z Quote Link to comment Share on other sites More sharing options...
