Fuel Line Fittings & Hose Connectors

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. JEGS offers a large number of fuel lines and fittings.

There are many different styles of automotive fuel line connectors for your car, truck, suv, or race vehicle. If the version you have is for a high pressure fuel injection hose then it should connects to a hardline, installation is fairly easy. You push the fuel line adapter on the end of the hose onto the hard line until an audible click is heard. The connection is completed. If you are using AN fittings, the hose end connector attaches to the stainless braided or nylon hose differently. The fitting is held carefully 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. Care must be taken to ensure that when assembling, the fuel line fitting doesn't "walk" off of the hose. Once the hose end is tightly connected, it can then be installed onto a matching fitting of a component by using aluminum AN fitting wrenches to prevent scratching. A large variety of JEGS AN fittings are available to meet your needs.

There are many different types of fuel line connectors. If the connector you are trying to remove is a quick release design made from plastic, from a high pressure fuel injection hose, a fuel disconnect tool is required. It works by simply pushing the tool in between the connector and the line, which releases the lock. The connector then will release from the line. If you are working with AN fittings. The connector is removed from the end of the hose differently. Aluminum wrenches are used to separate the fitting as it is two pieces. The inner part of the fitting will be released by a pull and twist motion. The outer part of the fitting comes off of the hose with the same type of method.

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.
