Exceeds OEM volume. These pumps go through rigorous bench testing and if they do not meet the minimum 5gpm they are torn back down and gone through again.Typically these pumps will produce 5.1-5.6 gpm which is usually enough volume to sustain 230/100 hybrid injectors. One year warranty is provided as well.
**The 94.5-95 trucks have a different front engine cover, and also have the anti-drain back in the pump**
**NOTE: WE HAVE THE OBS AND E99 HPOP FITTED WITH A 17* SWASH PLATE TOO FOR SLIGHTLY MORE VOLUME LIKE THE L99-03 SUPERDUTY TRUCKS.**
