Fuel Pressure Warning Light - The number one killer of the Dodge 24 valve injection pump is supply pump failure. In our truck shop time after time we have found trucks with low or no fuel pressue and the driver had no clue. So we came up with this, a low fuel pressure warning light. Easy to mount anywhere you want, this pump saver has warned many a driver his supply pump has failed. Thus the supply pump is replaced instead of the supply pump and injection pump!
Works on both 24 valve and 12 valve cummins
