IS IT A FUEL PROBLEM?? 

It boggles my mind that you guys haven't reached more subscribers. These videos are well put together, polished and full of entertaining content. I look forward to see what shenanigans yall are up to next.

Y’all’s sister definitely got the the better looks between y’all!😆😆😆😆

You guys deserve at least 500k subs by now. Love the content. Editing is great, got storylines, and you’re actually fabbing good stuff. Only way is up for you fellas.

I love that your sister is in on the practical jokes, she is most definitely a Peck!

Great Video! Your sister could easily steal the show though! Great face Caleb on your pressure checking!!! Lol

Haaa with family like that keepin your skills sharpened u cant ask for more. Lookes like your eyes were gonna pop out head when u blew 20psi😂

When a vehicle has a miss always pull and look at the burn side of the "SPARK PLUGS" YOU FAMILY SET ALL OF YOU UP FOR THE WOO WOO !!!!

Wow, watching your channel I never realized the 130k subs I saw was actually 13k subs. Ooooh this channel is DOPE AF! Give it time you fellas will have a million!

Internet search: A faulty door switch (that turns the dome light on and off) frequently causes a parasitic power drain. Other causes include a trunk/tailgate release switch that is always on, a headlight switch stuck in the “on” position, aftermarket accessories such as an alarm system or CD changer, damaged wiring harnesses, and faulty relays. From experience, when installing generic / inexpensive inline fuel pumps: Most inline high-pressure fuel pumps are designed to PUSH fuel, not DRAW fuel. So, if your inline fuel-pump is mounted in a location where the fuel tank outlet is higher than your fuel pump's inlet, then you're basically starving it for fuel. The fuel tank outlet line needs to 'gravity-feed' fuel into the fuel pump. Just a thought: Basic rule-of-thumb dictates that for every 1 gram of fuel introduced into the engine, you also require 14.7 grams of air. If your fuel system's throttle body butterfly valve is suddenly snapped shut (when suddenly letting off the accelerator pedal from WOT), then it's similar to suddenly placing your hand over the entire opening of the throttle body opening. In simpler terms, you're suddenly choking the engine of the air it requires for the amount of time it takes to idle back down. Check to see if the throttle body is clean and also that it's adjusted to spec's, as far as being cracked open a little with the idle stop screw adjustment. - I've encountered this same problem on everything from an old-school naturally-apsirated engine, to the current LPG electronically-controlled forklifts we operate at work. I really hope these thoughts may help you cure your fuel starvation problems - and I really enjoyed this content you shared with us, as it made a commonly frustrating AF scenario a lot less aggravating, by watching you solve issues in a humorous manner. Between your channel and Trail Mater, they are (by far) my favorite 'off-road' content to watch. - In your verbiage: Peck Brothers Off-Road is 'The Dean' ! Ha! 👊👊👊👊👊

Loved the video!!! Can’t wait to see these jeeps rocking and rolling!! Hoping to see some big sponsorships come your way!!!

It’s pretty easy to swap to an in tank pump, especially with that cell. You can also order those vette style filters with AN fittings already on them, and get rid of the adapters.

Caleb walking around like Jessica Simpson in them cut-offs😂

Love your vids wish I had some bros like y’all keep Up the amazing content

My issues with LS engines always seems to be fuel related as well. In my experience those corvette regulators everyone uses for LS swaps don't handle high flow pumps well. Everyone drops the Walbro 455 pump in their tank but those pumps have way too much flow for the cheap corvette regulator and causes weird pressure fluctuations like you saw on your gauge because so much fuel gets returned. This channel is great, keep it going.

For the power draw, I bet you it has the typical “JK” after market radio I noticed in the video it has installed. There is other videos on this problem. The problem is, and you can trace the draw, the computer will shut down, put to sleep a factory radio, the computer can not put a after market radio to sleep. It will keep drawing power. I have the same problem in my 2008 JKU with a after market radio. If you are going to keep the after market radio, start pulling the fuse for the radio to stop the power draw.

the arrow on the return is facing the wrong way 🤣😂 you guys are great!

Caleb looked like he was about to pop an eyeball when doing the pressure gauge thing 😂

So much wastet time. I would have been a little bit pissed 😅 but on the other hand, i would have checked the sparkplug a little bit earlyer. But it's easy to say from the distance 😂 (Sorry for my english. I'm from germany) But guys, I love your Videos 👌🏻

If you use the Corvette regulators you have to use the Wix 33737. Just went through that on another that had a cheapo brand from you know who. Wix to the rescue! 60psi all day now! Great video guys and give that girl a prize! 😂

New record for Dean references

What wiring harness you guys running on the black jeep. 'Dads jeep'

Guys ya gotta start using “Odyssey” batteries , made here in USA , AND THEY ARE AWESOME ! Have them in both my jeeps the extreme series model . They are pricey just under $400 bucks but my opinion well worth it 👍

That was funny as hell ! 🇺🇸🇺🇸🇺🇸🇺🇸

It’s amazing you guys don’t scan first?

Set the reg when running you have more voltage when it’s running

What I don't understand is that if that's cheap has a miss why would you not first check the timing and the spark plugs to find out why it has one cylinder that's not firing. It has nothing to do with fuel pressure because that wouldn't cause a miss it might cause it to run sluggishly or possibly have problems starting. The only thing that causes a miss or rough idle has to do with the electronics and the electrical system which means a spark plug or the coil or even a bad plug wire.

Hey have you guys ever had to deal with torque management with a factory gm computer? I’ve got a 5.3 ls jeep that’s a dog off the line. But if you drop a head going 20 it goes absolutely bonkers. I’m getting a custom tune next month. I’m hoping that’s my problem and not a stall related issue.

the boys sister is a dean!

Your diagram is incorrect for the Vette reg/filter. The 5/16" center isn't the feed, it's the return. The 3/8" outer is the feed. Not sure if you're actually plumbed that way on the Jeeps and it's just the diagram that's wrong. Cut one open. Enjoying the series!

Ask sister kallie shelped get you 3 boys real good with your dads help

“It’s just a prank guys” The prank: Worked out great for dad, he got a bunch of new parts lol

When is the last time yall went wheeling? It's been a minute.

Y’all boys need to look into the idle air control on your dads Jeep. Idle air control is what brings it back down to idle.

If you can't tell the difference between a fuel problem, and a misfire from the sparkplug wire being taken off yous 3 might be in the wrong business lol

What is a dean?

😂😂😂

Katie is beautiful

Y’all try cleaning the injectors? Very common thing.

Never use parts geek and the hell with Amazon

Caleb looks stoned

Hello From, ❤️ 👋 🫂 ❤️ 👋 🫂

funny how the girls sound just like there brothers.

Weld a wall in the tank with a 1 in hole in it and it won’t swish back and forth

More of your sisters. Absolute smoke shows.

God I miss Utah 😐
