Gentleman, there is a fuel hose replacement that meets and exceeds Chemical Resistance
including Bio Diesel B-20. Information for correct hose ( 451TC/ST ) , Cost per hose made
at Parker Hannifin Hydraulic Dealer With tax $ 44.00. How this came about, Rayne LA. Rally
in April had several people request hose replacement after inspection of there motorhomes.
At local Cat Dealer 20 miles away employees did not ever hear of special fuel line that would
work with Bio Diesel and could not help us. Note. I have paper work from 3 Cat dealer that
had made up our fuel hoses. 2 days later and lot of homework we found a Parker Hannifin
Hydraulic hose shop and had 5 fuel hoses made for $ 44.00 ea. Parker Hannifin is one of the
leading fluid power company's in North America. Leaving thought Roy Mueller changed out his hydraulic fuel hose on 1996 Beaver that was Parker brand and kind enough to cut open the
Hose for cross section inspection and the hydraulic look just like new. I carry this hose for
diesel seminar classes I put on along with Gates Global hoses that failed for show and tell to
members. Dave Atherton Retired Cat Mechanic
