Fuel line from duel feed holley
 

What is the best way to adapt the fuel line kit below for a dual feed holley to the stock mechanical fuel pump on a 454 mag (3/8 hard line). Is there an adapter fitting? It would have to be a JIC to 3/8" brake line type fitting. The local NAPA was not helpful. Thanks.

An fittings have the same degree flare as brake lines or they make -AN compression fittings but I don't recommend doing that. You will need a flare tool -AN nuts and Ferrells for hard line.

Actually, AN fittings have a 37 degree flare and a standard SAE flare is 45 degrees. There is a specific flare tool for each.

if you want to use AN stuff, take it all the way from the carb to the pump. Don't try to splice it together.

Your right don't know what I was thinking I have a completely different set for doing AN stuff.

That's how I did it on the Mustang.

The fuel line adapter (#11 in pic below) I believe is just 1/4" NPT going into the pump. Fuel line side, if i remember right, is 3/8" flare.

Easy enough to make something up. Hard line, AN Braided, AN Pushlock (my fav choice for low psi fuel), or etc.

If your Napa is like mine, they don't even know what a damn carburetor is. LOL.

Thanks for the responses. Since we already have the an style duel feed with pressure gauge would like to use it.

SM, so I would take the flare fitting out of the pump and replace with a pipe to an style adapter. Then get a length of an hose with the correct ends. Wlso the length of hose would need to be the right length. If I had the parts in front of me I could make it work but I dont.

Just seems complicated to hook up a simple carb

Like everything else, only complicated when you do something for the first time and have no local parts help. So, when you are done, it will be easy the next time...if there is ever a next time.

As a tech help, typically getting a 90* pipe to AN coming out of your fuel pump is a help...vs a straight fitting. This way your line goes up vs out and then have to bend to go up.

What size AN and if male or female from your Carb duel feed line set-up ?

What you need is a 90 degree AN adapter at the pump. Your pump is prob either 3/8 NPT, or 1/4NPT. Plus a 90 -8 hose end, and hose

or 1/4 NPT

Then for the connector at the fuel log

and the hose

SB, MILD thanks for the info that is very helpful. Yes we need a 90 at the pump outlet as it goes straight toward the engine mount. One more question, is a tool needed to install end fittings on the hose?
Thanks again
