fuel vapor return line genius idea!

The sending unit on my 66 Barracuda tank has two out lets. A3/8 for fuel to the pump and 5/16 for a return I guess. Is the 5/16 for a return or not, as I,m trying to install one to avoid a vapor lock/ fuel boil issue. Any help appreciated. Tim

This question is for those of you that are running a supercharger. I got all the right ignition parts i need. I have a Holley blue fuel pump. I am having trouble finding the right fuel regulator. Alot of them come with a return line port inwhich i dont need. They all also come with a vacuum...

...canister), I'm thinking to modify the extra line from the vapor capture "tube" in the trunk to the engine bay to turn it into a fuel return line so I can use a return-style regulator. I occasionally have minor issues with fuel percolation and I know using a return-type fuel system would help...

Hi all My 198 slant starts very easily and fast when hot, but when it has been shut off for a couple of days, I have to crank several times to get it back to life. The time required for the mechanical pump to refill the fuel line and the carb bowl. I planned to install an electric fuel pump...

I'm trying to figure out the best way to feed a healthy 383 I'm getting ready to install into my '75 Duster. I currently have a 5/16" fuel line, which is just not going to cut it, especially since I plan on adding a 75-100 shot of nitrous at some point in the future. I was thinking about...

I think that's a vapor return not open.

Not half. But it will bleed off some. That is, as long as you use a bypass regulator for the return orifice, OR use a fuel filter with a metered orifice return nipple. If you simply plumb in a straight return, then yeah, your fuel pressure will drop dramatically.

I'd look into something like this - fuel line return bulkhead fitting. No brazing needed, just need to drill a 9/16" hole in the sender face.

If you were ever to go to the drag strip they may not allow the fuel line going up the fire wall like that. Just an FYI to anyone routing fuel lines. Of course, if yo never go to the track it doesn't matter.

If you're running an electric fuel pump, you could tap a block off plate and drain it into the fuel pump mount. Heck, now that I think about it, the factory used a hollow bolt on the fuel pump for the return line on the police package oil coolers- so you could probably do that even if you're...

I currently run a Tanks inc EFI tank with the "corvette" style filter/regulator, which is a dead head system. I plan to change over to the return a return style system, which will require an additional line to the tank, a new regulator and filter.

Basically it is a return line , or vent...Like Fred said, you can put an extension hose on it and a filter and just keep it in the back of the car....

Considering getting a new unit as opposed to drilling holes for a return line. I see quite a few options over pages of looking. Might just try a bulkhead fitting, too. Any recommendations for a known GOOD unit? 'Good' would include a sender that works with the OEM gauge, a float that might...

Hello all, I’m still new to this and learning as I go. I believe with the 90+ degree days and heat index at 105 the last couple days in Miami and foreseeable future , I am certainly experiencing vapor lock conditions. After searching these forums and YouTube, I’m still confused in terms of...

For clarification's sake, there was never a SOLID FUEL return system on our Mopars. There was, however vapor return. I'm getting ready to run a return line on my truck, Gladys. I'm just going to run right beside the existing fuel line from the tank right to the engine bay.

I up-sized an existing return line nipple on the factory sending unit by using a step drill and a 3/8's steel line silver soldered together. Finding real silver solder took a minute though. The electrical pass-through fitting is from Radium Engineering. This sending unit can be fitted with...

Note that I am in AZ. I run a Holley 770 on my magnum. 3/8 lines up and back for a return system with both lines routed up the corner of the firewall and inner fender insulated then across to attach to a flipped backwards dual fuel feed hard line. My return T is right before the hard line that...

Thanks for posting this! I like that option!

...extra vent port on it but others have just used a tee fitting to connect to if they had just one vent port on fuel tank. Use a 1/4" fuel return line from Fuel/Vapor separator back to Fuel tank vent connection. REFERENCE: https://www.moparaction.com/2016/03/16/vaporware/...

Do you have a full bypass return or a deadhead return set-up? See here for more info. https://www.vaporworx.com/resources/fds/1-fuel-delivery-101/

I had the problem on Gladys where the fuel in the line between the carburetor and pump would drain back through the fuel pump towards the tank. I solved it way back then with a Dorman one way check valve. I've since replaced that fuel pump and redone some of the fuel system forward of the pump...

in process of getting my 67 up and running again. gas tank is full with 10+ year old gas so was planning on dropping and maybe just replacing the tank instead of trying to clean it... came upon the aftermarket setups with a fuel pump inside the tank for efi applications.. would this work on a...

I would look at your fuel rail. If it has a return port and a FPR (doubt it does) than I would use the one with a return port. Pretty sure your factory setup was returnless. I know the later cars, even the Hellcats were. I know some swear by a return style fuel system when getting into big...

When I got my '74 Duster, the factory tank was gone, along with the spare tire well. Slab of sheetmetal on the trunk floor and a fuel cell on it... I wasn't a fan. I got lucky, found a very nice trunk floor, tank, and 5/16" pickup/sender from a '73 Valiant and stuck them in. There are no ports...

I was considering swapping from a carb setup to a Sniper setup, which (I believe) requires a return line. Seems like a good way to kill maybe more than two birds with one stone.

Vapor lock would be my first guess, too. Ii have had that exact same problem from the fuel line running too close to the header tubes. I wrapped that section of line with thermal insulation tape and problem went away.

I used the Bouchillon Bracket to mount 2 return springs: Fuel line connecting 4 inlets is next before I am done. I am gonna shelf this thing until I get other stuff done.

I have a 1972 Plymouth Duster and am trying to replace the vapor return line. Mine is 2 piece, 5/16" OD and all pre-bent manufacturers seem to say the line should be 1/4". I see listing of 5/16" for 1971 and wondering if that is the line my car has for some reason. For mine the line routes...

67 A bodies have a tube on the top of the filler neck that goes to a U shaped hard line tube that follows the filler neck down through the trunk floor and terminates open to the atmosphere inside the rear driver's side frame rail. The extra tube on the sender is for later years return line from...
