Tork Tek Adjustable Overflow Valve OFV030
The TorkTek adjustable overflow valve is a major improvement over the non-adjustable, wear-prone factory overflow valve.
The OFV030 resembles a stock overflow valve but the seat depth is different, the ball diameter is not stock, the inlet hole is enlarged and the exit holes are now six total to smooth out fuel pressure and prevent pressure spikes.
This is a good upgrade to pair with the Power Driven Diesel Predator lift pump or if you have a conversion with electric lift pump supplying mechanical pump on Cummins engine
The OFV030 is fully adjustable from 20 to 40 PSI.
