Tig-welded 6061 aluminum material provides more efficient cooling properties

The magnet captures ferrous particles for extra fluid protection

increase EGT’s

It eliminates potential low fuel rail pressure DTC codes P1093 or P0087 (low fuel rail pressure during power enrichment) that are caused by an insufficient pressure relief valve (PRV) spring pressure

Both pumps work together

2002-2004 GM 6.6L Duramax 6mm 5-ply Silicone Hose #4 (d) PRI Tig-welded 6061 aluminum material providesEach PPE Performance Silicone Hose is strengthened with 5 plies of Nomex reinforced fibers making them very tough. Fluorocarbon lining offers better lubricity (slippery and resistant to chemicals) and the silicone rubber construction ensures they can withstand constant boost pressures and temperatures from 76 degrees all the way to +437 degrees Fahrenheit. PPE silicone will maintain structural integrity even when subject to high boost pressures
