sccaracer@tampabay.rr.com Report post Posted June 30, 2010 I must replace the plastic cooling system fill/catch tank on my 1999 Newmar Dutch Star with 300 Cat. My concern is that the new replacement tank comes with a cap of different design (old cap won't fit new tank) and is a different pressure (old cap 13lbs. new cap 15lbs) Is this difference likely to create any problems for me?
