Since everyone seems to be on fuel issues, not so strange with these, anyone know what the output volume should be.
I have read one pint in thirty seconds and one quart in thirty seconds.
Kind of a wide range.

 

Good luck getting answers

 

The spec for a 4.3L CSFI pump is 22 grams per second @14.2 VDC, (1320 grams per minute). Gasoline, (depending on Winter or Summer blend) is ~6.2 pounds per gallon. Doing the math works out to roughly 2 quarts per minute, or a pint in 30 seconds, which has been the "rule of thumb" for many years.

Edit: added calculation

 

The best I can find is somewhere ~1 gal/minute.

 

Actually, 1 gal a minute may be right. Just put a new pump and the return line was broke. Truck was running for 2-3 minutes and lost almost a quarter tank in the grass
