I was wondering if any of the local parts stores (NAPA, O'Reilly etc...) would carry the diesel rated hoses. I need to replace my lines ASAP, as there are leaking diesel all over and I am now without a truck. Also, if these places do sell the lines, will they be good for running bio or SVO in?

 

Your best bet is to get your hoses from a diesel shop if you can. Cat, Cummins, etc. or contact a hose manufacturer like Goodyear for distributors. A Napa that supplies parts to trucks and industrial customers may have it too.

 

I think Larry B's sells it buy the foot also.

 

Try looking at a marine supply store, I bought Coastguard approved diesel fuel line . It is rated to last better than DOT approved. Price is comparable to DOT approved. I paid $1.09 per foot, for 3/8", and $1.29 per foot for 1/2" Both were rated for #125 psi.
Just my $.02.

 

Any Parker store would have line that would hold diesel. Bring your wallet though, I spent $200.00 on line and fittings alone.

 

If you want to shop online, McMaster-Carr has several types of suitable hose.
