Normal or a problem?
I recently installed a fuel pressure gauge and when I pumped up the pressure with the lift pump I noticed a hissing from the front of the injection pump area after pressure built up.
Is this a leak that I need to trace or maybe overflow valve engaging or ??????
Truck starts and runs fine. No drops or spikes in fuel pressure. Sits for a few days and still holds prime.
I question this because I lag a little more than I think I should getting to boost. Is this right or needs to be fixed?
Thanks in advance!
