Anyone know what the stock fuel rate the 6.5 lift pumps pump at?

There should be a label above the rad. that lists the fuel rate. On my truck it says about 61mm3. Max. fuel rate with a chip is around 84mm3? Correct me if i'm wrong. Leo

I just checked my lift pump the other day and it was at 7 PSI with the truck idling. I don't know the spec. for volume of fuel.

Walbro FRB-5 is one I decided to go with but I'm fueling for heavily modded engine, most folks be just as well suited with one Heath sells, a derivative of the pump intended for the 93 6.5s with a mech IP.
