Just about to install a new Edelbrock carb on my Volvo and the original fuel line from the fuel pump will not work. Has anyone used a flexible line in place of the steel line?
Thanks,
Speed

coast gaurd says it needs to be a reinforced steel braid hose. also if it going to a slide on fitting it needs to be barbed.

thanks fkboatman i found some braided hose that should work. i also found a small solid piece that comes out from the carb and goes under the linkage and then use the braided stuff from there to the pump.

thanks for your help.

In reality, USCG regulations on pressurized fuel lines are based on their ability to withstand burning and vapor penetration. Non-pressurized line, tank to pump, is available and will have USCG approved printed on it. As far as I know, no aftermarket stainless braided hose meets the regulations for pressurized.
If you're concerned about USCG regs, because of liability issues, stick with a mechanical pump and hard line.

The flexible fuel line may be hose, "USCG Type A1" or "USCG Type B1," depending on compliance with the criteria of 183.558.

Do a search. This topic has been covered hundred of times.
Like said above to be compliant it must be stamped on the hose. Also think about insurance adjuster if you have a claim.

I found this one but a little pricey

i think if the hose is USCG Type A1 it is ok
here is what i found on this web site

FEDERAL LAW
183.558 - Hoses and connections
(a) Each hose used between the fuel pump and the carburetor must be "USCG Type A1" hose.
FEDERAL LAW183.560 - Hoses clamps: InstallationEach hose clamp on a hose from the fuel tank to the fuel inlet connection on the engine, a hose between the fuel pump and the carburetor, or a vent line musta) be used with hose designed for clamps.

This requirement does not apply to a tube used to detect fuel pump diaphragm failure.
Hoses may or may not be designed to be clamped, particularly wire or the mesh reinforced hoses. The proof of whether or not a hose is satisfactory is that the hose connection does not leak when subjected to the "Static Pressure Test for Fuel Systems" as required by 183.542.
TO COMPLY WITH THE LAW· Have you selected hose for your boat’s fuel system that can work with hose clamps such that connections will not leak when subjected to the "Static Pressure Test for Fuel Systems" (183.542)?



FEDERAL LAW183.560 - Hoses clamps: InstallationEach hose clamp on a hose from the fuel tank to the fuel inlet connection on the engine, a hose between the fuel pump and the carburetor, or a vent line mustc) Be beyond the bead, flare, or over the serrations of the mating spud, pipe, or hose fitting; and (see 183.560)

This requirement does not apply to a tube used to detect fuel pump diaphragm failure.
Any hose to be used with hose clamps and installed in:
(a) the fuel tank vent line;
(b) the fuel line between the fuel pump and the carburetor; or
(c) the fuel distribution line between the fuel tank and the fuel inlet connection at the engine (this connection is often at the fuel pump)
is required to be assembled with the hose clamp:
(a) at least one-quarter inch from the end of the hose, and
(b) beyond a bead or flare, or
(c) over serrations or annular grooves (183.530).
NOTE:
Wire types of hose clamps are not acceptable.
FIGURE 27 - Examples of Satisfactory Installations
TO COMPLY WITH THE LAW· Is the hose clamp beyond a bead or flare, or installed over the serrations or annular groves, depending upon the design of the hose barb fitting?



FEDERAL LAW183.560 - Hoses clamps: InstallationEach hose clamp on a hose from the fuel tank to the fuel inlet connection on the engine, a hose between the fuel pump and the carburetor, or a vent line mustd) Not depend solely on the spring tension of the clamp for compressive force.

This requirement does not apply to a tube used to detect fuel pump diaphragm failure.
Hose clamps are available that use different means for securing the hose to the hose fitting, pipe or spud.
(a) Mechanical Tightening: This type employs a screw or bolt to apply pressure to the connection. A screwdriver, pliers or wrench is used to adjust the hose clamp depending on the adjustment configuration. These clamps are reusable.
NOTE:
Wire type hose clamps are not acceptable.
(b) Deformation of the Clamp Material: This type usually depends on the use of a special tool for installation. The clamp material is bent or formed in such a manner as to apply pressure to the hose thereby securing the hose connection. Generally this type of clamp is not reusable and may be difficult to tighten in the event of a leak. This style of clamp requires a specific tool for correct application. Since technicians in the field will not have access to these tools, these clamps should not be used on connections where routine disconnection for servicing may be required.
(c) Spring Type: This type is prohibited. The compressive force depends on the clamp material and there is no positive mechanical type of fastening.
