Listed here is a USED Volvo Penta Fuel Hose.  This is a Genuine OEM Volvo Penta part NOT a cheap Chinese aftermarket replacement.  The part number for this hose is 3862635 and lists for $255.49 new from dealer.  All have some minor wear, staining, pitting, scuffing, etc. consistent with parts of their age.  They have some wear from use on outer hose casing but not through the outer protective braiding (please see pictures).  Not guaranteeing operation of the threaded ends o ring.  Worked fine upon disassembly but should be replaced per service manual.  O ring part # in case you want to get one from your local dealer is 3850424 or one can possibly be sent for an extra cost if in stock.  This is the hoses that connects the VST fuel pump assembly to the fuel rail.  This is the SMALLER hose.  Normally it fits the starboard stern fitting on the Vapor Separating Tank and the lower smaller terminal on the fuel rail on many MPI V engine configurations from the late 1990s well into the 2000s.  May be used on other engine platforms, sizes, years, locations, and configurations over the years as well. It measures in at approximately 34 1/2" from end to end.  It is a USCG Type A1 SAE J1527 Teleflex marine compliant hose.  I ALSO HAVE SOME LONGER ONES IN CASE THIS DOSENT FIT YOUR ENGINE.  Those can be measured upon request and a price given if one of those is desired.  Two of these hoses came from a pair of 2006 5.7 Osxi-E engine that came from a freshwater Orlando chain of lakes and had never seen salt water. Cant remember where the other two came from but were from a similar engine. One of the hoses you see pictured are one of the actual hoses you will receive with nothing extra.  If you prefer one over the other please feel free to contact me and I will do the best I can to accommodate you.  Fuel lines are stored in a climate controlled parts room to prevent deterioration.  If you have any questions or need help with compatibility please feel free to contact me before purchasing and I will help you to the best of my abilities.  Thank you for your interest.  Steve MMSLLC :)
