- Today we continue our "How to LS Swap" series with part 7, finishing up the fuel system. After this video the fuel system is essentially complete. I am creating this series to show that anyone can LS swap a vehicle and have a fun project. If you have any questions please leave them below!

As someone who's working on their LS swap as we speak, I do appreciate the summit links in the description, that eliminates the need to search their massive site 👍
Nice work! Let me know how it goes! Thanks for watching!
Now that I’ve googles the meaning of bespoke, I can continue watching this series. 👍
Good job, you kept something very simple, SIMPLE!
Thank you for your video. It turned out I was over thinking this kit and install. This made me realize I had installed my fuel system and regulator property. Still working on the project so havent been able to test it.
Great job!
Looks mint!
Thanks for watching!
You can also put a guage right on the regulator on that port on the front of it using a cheap adapter. That saves having to add than 2nd AN connector with a port on it. Great videos - really appreciate them!
He's trying to make people buy more parts than you need 😜
He can also remove the guage and use it for another build if he left enough hose length
My LS swap runs great with the stock GM fuel system and I get great gas mileage & horsepower, I remember just adding just one AN fitting to the fuel line. I feel like summit is trying sell something we don't need.
That's great! But I don't have any stock GM stuff to use. Thanks for watching!
Awesome great video thanks 🙏
My pleasure!
First time watching your channel. Dude! I hope you don't take this wrong but you're the Bob Ross of car how to. I just happened on your channel because I'm doing the same thing on my 55. You should butterfly your adel clamps for the fuel lines(looks better) and on the vent put a standoff or spacer where the filler tube attaches and secure it there. Good install though.
Your videos are great
I appreciate that!
@@2carpros how do I go back and watch episode 1 I’m going to do the same thing to my 55.
Only Problem is I can't have any fuel lines on my firewall.
How far from the carbs can I be with the regulator? I'm thinking of going all the way to the front then up to the front of the motor. I don't have any place to mount the regulator up by the blower. Can I put it on the frame and run a 24in long line up? What kind of pressure drop will I see on acceleration?
This is for my 57 Blown SBC 750hp dual 750s
Do you have to put some type of sealant on fittings ?
First off merry Christmas from the Mississippi Delta!
So question...why did you cap off the rail closest to the regulator and route the feed line further away? Is there a space issue behind the closer rail that we can't see or is there another reason?
Merry Christmas!
I thought it would look snazzier and it's too close to the firewall. Thanks for watching!
What is the part number on that rollover valve?
Hey Ryan - love the videos! With a return line, diagrams I have seen put the bypass regulator after the fuel rails so it's controlling the pressure in the rails as fuel is consumed, and the guage is seeing the rail pressure. Pump -> rail1 -> rail2 -> regulator. Do you get any problems running it before?
Thanks for watching! I don't see a problem running it that way, just seems a little more complicated.
As fuel is used the pressure drops so the regulator will let more in for our set up.
@@2carpros why didn’t you apply your gauge in front of the regulator
@@irvingbar4569 Because then you would only see unregulated pressure. We want to know what the pressure going into the injector is. Thanks for watching!
@@2carpros my apologies I meant on the regulator in front were it has a plug
Great video Ryan! Couple of questions: 1) I thought AN sizes were 6, 8, 10 but you have 7 and 7.5 wrenches - are those from Summit?
2) you reference another video where you make the fuel you make the fuel line?
Thanks for watching! Actually ICT makes them. They work great! Really makes putting the lines together better.
Sure, here it is, it's steam lines but they go together the same way as fuel lines. ruclips.net/video/N3AkbwntZKw/видео.html
AN (Army/Navy) is just first number of 1/16 increments. 3 =3/16”, 6= 6/16” so it’s a 3/8”, etc.
Thanks for the upload. Iam still confused about the regulator. My 350 with 650cfm and 320hp is low in pressure I think. What regulator makes sense? Bypass? Back line? Dead head? Want just have a in and out to the carb. Possible? Thanks
Yeah just have a line run from the fuel pump to the regulator, regulate down to 8 psi, run the return to the tank, then run the pressure line to the carb. All done. I'm assuming you have a pump in the tank like this setup. Thanks for watching!
Nice video made it look so easy whats the name of the clips you run the hose threw then screw it to the frame
Awesome! Thanks for watching! Those are called cushion clamps and I believe those were 3/4" in diameter.
@2carpros ok thanks
Can I route this setup for a 327. Edelbrock has a max rating of 6.5 on its AVS2. However, I live in the southwest and want to monitor PSI with weather conditions. Let me know your thoughts, thank you!
Yeah definitely! You just might want a smaller gauge capacity so the resolution of the gauge is easier to see. You also could go with a way weaker fuel pump if all you need is 6. Thanks for watching!
Are you going to hook up the vacuum line to the intake ? Does it need too if your only to be NA
Do you mean like for PCV? I go over that in a later video in this series. Thanks for watching!
Whoch video is it on?
I have a turbo diesel, where do i run my vac line to? Does it need to be a BOOST line or a vac?
bro i have 2004 ford expedition but i accidently engage my 4x4 L but now it wont g out of it i even put out my shaft also but still no change can you please help me in it

How did you set up the return line ?
Out the bottom of the regulator and to the return on the tank. Thanks for watching!
So how do you run lines with dual tanks I’m having a problem with this do I need 2 of everything?
No. You just run a send and return from the tank to the regulator and then one line out the send of the regulator to the injectors. Thanks for watching!
@@2carpros what about the 2nd smaller tank? Do I need to do anything to the tank switching unit 89 f150
brother what size fuel line are you using?
-6 an fuel line. Thanks for watching!
Why not mount the fuel pressure gauge to the regulator?
Why using a plug plus adapter to fuel rail instead of using a plug directly to the fuel rail?
Why using 90° adapter instead of using hose end elbow? 🤔
😂 😂
Because there is no 1/4 npt fitting on the regulator. It's a straight piece with a thread for a gauge literally what it's for. Thanks for watching!
Also curious…. The vacuum reference is what he’s talking about. Can I just tap this anywhere into my intake manifold?!
