Search results for query: fuel return line

I used a model very similar to the ones shown in the link posted just above this post. I never went back and posted pictures for this response, so here they are. Sorry for the delay.

We did something similar to this when I raced outlaw karts with cr500 engines. We would put a carb jet in the return line otherwise it would starve the carb for fuel and just send it all back to the tank. Interesting how stuff crosses over.

I have two Carter competition carburetors on top. I have a stock type sending unit that is 3/8 into the tank to the tank. Pickup filter. Line comes out down to the lower part of the frame where there is a red Holley fuel pump with a 100 micron filter and a 10 micron filter coming in and out of...

1984 Jeep Grand Wagoneer, 401 (.030 over), Edelbrock clone 1406 4 bbl carb, 727 auto, Selec-trac NP229, AMC 20 REAR - D44 FRONT - WT - 3.31 ratio, 4" high arc spring lift. Rolling project currently licensed, insured, and driving. No problem running with traffic on the interstate, as I was...

Stay away from a Holley or Carter pump. If you can afford a new Mallory 140 I’d use that. You can find them used on fleabag cheap sometimes. Then I would suck it up and use the Mallory 29388 bypass regulator and run a return line. I don’t do any electric fuel pump systems anymore without a...

Just what I tagged you and Matt @Mattax in last night or this AM. So it smokes terribly. It does have 13" of vacuum at idle, but on both ported and manifold vacuum ports. Guessing the throttle blades are too far open. The idle mixtures screws do nothing, even all the way in, runs fine...

Good call on the vacuum modulator. I’ve had Fords suck trans fluid up and foul plugs before. Sounds like a solid plan of attack. Keep us posted.

Is it actually a return line or a vapor line? I'm guessing it's a vapor line. My 68 A-body has 1 fuel line. The tank is vented at the fuel filler tube. My 73 Challenger has two lines. One is the feed and the other is the vapor line. The vapor line runs from the vapor separator back by the...

Yeah, I was jokin at first about the line being a reserve tank, but he's gonna need every bit of it with that pump.

And that is an old picture In the mean time I've added a new 3/8 fuel line and converted the old line to a return Even less worry about vapor lock now

Edelbrock #8089. Advance shows it in stock.

Oh Lordy, dude. You have no idea what a mess is. Your shop is a pristine operating theater compared to mine. I have to slither sideways all over to access areas of the shop. If I put on five more pounds I won't fit at all. I should go get you some photos but I'm not sure I can do so and survive...

i have a non by pass regulator on my 440 now with two carter carbs, here is the issue i left the non bypass reg in place but oppened it up to use it as a fuel block for the two carbs...i also added a by pass regulator with a return to the tank. turns out the fuel sending unit has a 1/4 return...

I would think 3/8 line would feed it plenty of fuel??

...run anymore on street-going vehicles if I can. I think after I move I will be upgrading the fuel system on the Duster to have a fuel return line with pressure regulator and an electric pump as I have a feeling once I jet up to compensate for the lower altitude the increased fuel demand will...

Okay so I would be able to tee that back into the fuel tank using a fuel sending unit with the extra fitting, this will help with my hot starts? Tried the heat insulated don’t like how it raises my carb up.

Thx . I'll pm you a picture tonight of the issue.

Just cap off the return on the sniper. The regulator that is built into the holley in tank pump is set to the proper pressure for the sniper. My car has ran perfectly on the street and track. The stock 5/16 hardline is good enough for me, I've been 11.55 in the 1/4 and didn't have a fuel...

I think you need to do a few things before getting too far along here. Its great your doing this project and want to push ahead, but a little prep will go a long way to getting to the end results quicker and safer. You'll need tachometer and notebook to go with the timing light. Use timing tape...

Where does the original post mention a return line?

73 Duster is the car. It’s going to have a number 10 fuel and return line. So I need a vent capable of that much return fuel at low engine speeds/pump demand. I’m trying to find a way to keep the vent from letting dirt into the tank and to make it safe if the car gets into a crash situation. If...

That is clean! Nice work. Any idea what the amp rating of those connectors/terminals is? I'm curious if they'd work for a large electric fan.

OK, made some good progress since my last post which was about a month go. I pretty much have the gas tank, fuel filter/regulator and associated bits and pieces in for good. Took a lot of staring at the bottom of the floor to make a decision on how to make it happen. I had been trying to avoid...

I wanna run a 1/4" Fuel-Return Line along-side the 5/16" line for Fuel-Boiling reasons... in my '65 Barracuda with a 273 2bbl manual pump. The Pickup in the Tank doesn't have the extra return nipple So, 1) Will I have to Drill into the Tank for the Return? 2) Is the Location in this Picture a...

The gear was my only concern. Couple that with a return and it could run into trouble with a stock pump.

There does come a time, but his stock block 318 with 302 heads, 625 carb and his cam isn't the time of demand. Certainly nothing wrong with upgrading it, but at his build he won't "need" it. I've had more motor and used the stock fuel pump with factory 5/16 fuel line without issue. Many...

I run a Mega Squirt 3 Pro ecu in my mpfi slant six. It has been in use since 2016 and has been reliable. The intake is a Clifford 4 bbl unit that I drilled the NOS bosses to accept the fuel injectors. The injectors that I use are Ford 460 units. There are on line FI sizing calculators that can...

Car has 2 two lines going all the way up front . I don’t know if it’s a vapor line or a return line . My tank also has 4 vents up above the rear . My A body’s I don’t think have ever had that either

The Mallory part number is 29388. Far better than that holley regulator. Any time you see a bypass regulator that has the fuel enter the regulator backwards from a dead head regulator know that that design was used because it was cheap to get to market. Holley was way behind on bypass...
