Fuel return hose 1500 mm 649/51778 JCB, aftermarket

For the JCB machines: fuel return hose 1500 mm 649/51778, an aftermarket part. According to the product card, this is a 1500 mm return hose.

The hose is chosen by part number according to length, inside diameter and end fittings, and the length on the card is set for its location. An over-long hose kinks and restricts flow, while a short one is stretched and pulls off its fitting. When the hose is changed, renew the clamps too and make sure it does not touch sharp edges or hot parts. Never fit a hose meant for another purpose in place of a fuel hose, as fuel dissolves such hoses from the inside.
