To install the new fitting, it is held in place in a vise with the help of a Vise Jaw Protector to prevent it from scratching. The hose is then installed with a push-and-twist action until it is seated all the way onto the outside of the hose. The inner part of the fitting is then lubricated and pushed into the hose and then tightened to the other piece.

How to fix a leaking fuel line?

If you have a leaking fuel line connector, the first and preferred option is to replace either the fuel line connector or the line that contains it. This will make replacement the easiest and most trouble-free connection. If this is not an option, safely disconnect the leaking connector and inspect it for the reason it is leaking. If it contains a seal that needs to be replaced, locate and repair the connection with a new one. Inspection will usually reveal why the connector is leaking. It is not recommended to use sealants or products that patch up a leak as these will not work for very long and could get into the fuel system and clog it or break, causing a potential fire hazard while driving. Race car fuel lines may be an option to upgrade and replace the existing line. If you have a leaking hard line in between connectors, a brass compression fitting can be used to connect the break after cutting and cleaning it.

What is on top of a fuel cell?

On top of a fuel cell are fittings that are available for many different applications. In every case, one of the fittings must act as a vent to relieve pressure as fuel exits the fuel cell. The vent can also be combined with the roll-over valve, which prevents fuel from leaking out of the fuel cell, should the vehicle end up inverted. However, when the vehicle is upright, the check ball in the roll over vent is in the open position, allowing the fuel cell to breathe. If the vehicle fuel system requires a return back to the fuel cell (such as when used with a high pressure fuel pump), the other fitting is used for the returning fuel for recirculation. Any unused fittings on top of the fuel cell should be capped.
