How to LS Swap - Episode 7 - Fuel Pressure Regulator and Lines

[@3rd-Eden]

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 👍

[@2carpros]

Nice work! Let me know how it goes! Thanks for watching!

[@juliansdiamonds]

Absolutely beautiful job on that installation, bro !!!! Thank you so much !! I'll be doing this soon !!! 2010 camaro ss !!!

[@2carpros]

I'm glad it helped you out!

[@brucechick2937]

Good job, you kept something very simple, SIMPLE!

[@jamieK111]

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!

[@jessebb193]

He can also remove the guage and use it for another build if he left enough hose length

[@Junkyard_Dave]

Not sure what that gauge is going to read in the vacuum port

[@2carpros]

It's not to read vacuum. It's for boost reference to add pressure in relation to boost. Thanks for watching!

[@mustanglover1186]

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.

[@2carpros]

Great job!

[@briangarduno2501]

What is the part number on that rollover valve?

[@invisableobserver]

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.

[@2carpros]

That's great! But I don't have any stock GM stuff to use. Thanks for watching!

[@RandysFiftySevenChevy]

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

[@55Dag]

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.

[@Bigislandguy]

Hey, Newbie here. I recently bought a EFI conversion and I’m pluming my regulator like how you did. In- out and return with only one line on the fuel rail. I made brackets and got the regulator and filter mounted and then I seen the regulator bypass plumbing diagram in the instruction manual. My question is will I end up with the same result?

[@Bigislandguy]

Meaning will it work.

[@jaybrintnell7624]

This was awesome, thank you! I am about to install one of those in my Camaro. My only question is why did you not Mount the gauge on the front of the regulator

[@rogerbelcher2981]

I plan on doing something very similar to this on a 69 Chevelle but I plan on using the factory 3/8 stainless steel hard line for the fuel supply and ptfe hose for return. My question is to go from tank to hard line can i use a compression fitting to 6an or just use hose clamps at the hard line and an fittings at the intank pump.

[@2carpros]

I've seen people use the compression fitting to 6AN but I've never used them. In my opinion it is tough to trust since it was only ever designed to handle 8psi or so. I like to just use the 6AN from the pump all the way up so I know the fittings won't ever have a problem. Thanks for watching!

[@tojones1967tj]

Nice video made it look so easy whats the name of the clips you run the hose threw then screw it to the frame

[@2carpros]

Awesome! Thanks for watching! Those are called cushion clamps and I believe those were 3/4" in diameter.

[@tojones1967tj]

@2carpros ok thanks

[@BillyP-49Chevy]

This is my first time hooking up fuel for boost and motion race works is saying that you always put the regulator after you put the fuel to the rails. They said if you put the regulator before the fuel rails that's the last couple cylinders may not be getting the proper fuel after hitting the first five or six. They're saying each injector takes pressure and by the time it gets to the end of the rails you will have lost pressure but if you put the regulator after that it's fine. I copied you but yet I'm still so confused because everyone saying do it differently.

[@fuelbasti]

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

[@2carpros]

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!

[@bigripdeniro1952]

Do you have to put some type of sealant on fittings ?

[@jesseveazey230]

So how do you run lines with dual tanks I’m having a problem with this do I need 2 of everything?

[@2carpros]

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!

[@jesseveazey230]

@@2carpros what about the 2nd smaller tank? Do I need to do anything to the tank switching unit 89 f150

[@vgslife9640]

Great video

[@bluethunder1951]

Not what anyone on a budget would do, looks like a ton of fittings to cause potential leaks. The fuel filter could be on the regulator with a hard fitting, as could be the gauge, and having soft host from tank to regulator is dangerous for pinch points or rubbing causing leaks. Only thing I learned here was to buy from Summit.

[@520dblock3]

Wait, I'm doing my own Ls swap, I'll need a regulator to feed my LS ??

[@2carpros]

Yes. The LS injectors want 58 PSI of fuel pressure. The pumps usually put out around 90. Thanks for watching!

[@520dblock3]

@@2carpros Thank you

[@madrabbit9007]

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?

[@2carpros]

Merry Christmas! I thought it would look snazzier and it's too close to the firewall. Thanks for watching!

[@jjones7831]

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!

[@2carpros]

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!

[@jamieK111]

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?

[@2carpros]

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.

[@irvingbar4569]

@@2carpros why didn’t you apply your gauge in front of the regulator

[@2carpros]

@@irvingbar4569 Because then you would only see unregulated pressure. We want to know what the pressure going into the injector is. Thanks for watching!

Snazzy !

[@KrypticKoncept]

How did you set up the return line ?

[@2carpros]

Out the bottom of the regulator and to the return on the tank. Thanks for watching!

[@007_jg8]

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?

[@2carpros]

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. kzbin.info/www/bejne/hGSknJWto9mNgdk

[@808kahulaa]

AN (Army/Navy) is just first number of 1/16 increments. 3 =3/16”, 6= 6/16” so it’s a 3/8”, etc.

[@fasst5511]

That FP gauge under the hood is cute but worthless for any real diagnostics. You should replace it with a fitting with a schrader valve like ALL factory fuel rails have so you can connect a pressure gauge with a hose you can read outside of the engine bay. One you can see while driving. As a tuner the #1 problem I see on swaps is fuel delivery problems. You can have perfectly fine FP when idling with the hood open to see your pretty little gauge but have low fuel pressure while driving and at WOT when the fuel demand is high. I see too many times on swaps there is no way to hook up a real diagnostic FP gauge.

[@travisgallegos9363]

Bro the return makes no sense. You have a deadpan set up. What’s returning?

[@23F150RACERED]

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? 🤔 😂 😂

[@2carpros]

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!

[@Gold_Medal_31]

Also curious…. The vacuum reference is what he’s talking about. Can I just tap this anywhere into my intake manifold?!

[@rogerwilson821]

What a screw up. This way is not right , pressure gauge is mounted on the out let side not the inlet . Also the reg has a out let on the front for the pressure gauge. don't set up your fuel regulator this way your wasting your money and time.
