I have a 1995 dodge ram 3500 with the 5.9l magnum. I recently replaced the fuel pump (fuel pump link below), and metal fuel lines with .25 in nylon lines. I ran the engine for a while and everything ran fine ( the idle was rough, but it has been sitting since 2016 so that isn’t a surprise). Now its a week later - I put like 3 gallons of gas in it - and now fuel is splashing out of the throttle body. i have a good video of it linked below. I just removed the throttle body and cleaned all of the sensors off. But it still doesn’t work. What do you guys think? Thanks for helping!

You didn’t say what year it is… I’d be looking closely at the fuel injector O-rings or a cracked injector… Maybe use a mirror to hold over the throttle body and just turn the key on to see if you can see where the fuel is spraying from… EDIT: I didn’t see the fuel rail (port injection)… ---

Its a 1995, so you believe that one or multiple of the fuel injectors have gone bad. How would that cause it to splash back up? Just curious ---

Yeah I didn’t see the fuel rail the 1st time… Can you take a picture of the top of the throttle body?? But you need to look inside the throttle body (safely) to see where it is coming from… ---

The timing chain may have jumped time. If the intake valve for each injector isn’t open when the injector fires, the fuel has nowhere to go but out the throttle body. Tester ---

Remove number 1 spark plug and rotate the engine until you have compression coming out of the spark plug hole, bring your timing mark on the balancer and line it up to the front cover timing marks 0 degrees (TDC), remove the distributer cap and the rotor button should be pointed at the number 1 terminal, mark it before you remove the dist cap… ---

Remove the distributor cap. Take a breaker bar/socket and turn the engine by hand at the crank bolt and until the timing mark points to zero. Now turn the engine in the opposite direction while someone watches the rotor in the distributor. If you’re able to turn the engine 5 degrees or more before the rotor in the distributor begins to move the timing chain is stretched or has jumped time. Tester ---

Looks like you connected the fuel supply line to the purge line at the front of the throttle body. The fuel sprays when the fuel pump is actuated before the engine begins to crank. That is not a valve timing issue. That is a fuel delivery issue. If you pump enough fuel into the manifold, you will hydro lock the engine. ---

It’s a dry manifold/throttle body, it has Multiport fuel injection, no fuel at the throttle body… ![14-783_S](https://global.discourse-cdn.com/cartalk/original/3X/c/2/c274ef2346d89e7dcb5aa186db811b1fb55a40ae.jpeg) ![14-783_T](https://global.discourse-cdn.com/cartalk/original/3X/d/c/dc586a94c1f3f7a6b8959e45be5340f7a3f339b4.jpeg) ![14-783_B](https://global.discourse-cdn.com/cartalk/original/3X/3/f/3f65449d978337201cfe5c727fcf0651538ac484.jpeg) ---

I don’t believe that much fuel could make it from the fuel injectors to the top of the manifold and spray out like a fountain. The barrel manifold could hold two gallons of fuel before fuel can reach the top. Also, there shouldn’t be that much fuel primed before cranking the engine. ![20250611_080745](https://global.discourse-cdn.com/cartalk/original/3X/3/6/36b7cf002846d4ff40545d248526347814a89c63.jpeg) ---

Heres more info on how the fuel lines r ran. Maybe it is how i hooked up the blue connnector there is sitting fuel in the intake manifold. Im going to siphon that fuel out, connect the blue connector correctly, and theb go from there [![](https://global.discourse-cdn.com/cartalk/original/3X/8/6/86d39bbf795d276caf2d16e4fd2df8b2d96abaaa.jpeg "June 11, 2025") ](https://www.youtube.com/watch?v=VLFIXBDbKpc) ---

The high pressure fuel line connects to the fuel rail. ![image](https://global.discourse-cdn.com/cartalk/original/3X/8/3/8360ccbeb94830559291b6d915f32d7294a8a065.jpeg) The hose connected to the front of the throttle body should be connected to the purge solenoid to collect vapors from the EVAP canister. ---

> [@reidt.layne06\_193863](#): > > Heres more info on how the fuel lines r ran Wow. That’s wrong on top of wrong with a side of wrong. If all your fuel is coming in from that hose before you teed it off, where are you supplying fuel to the injectors? And why is there a low pressure fuel filter attached to what should be a high pressure line that’s now plumbed with low pressure hoses? This is an engine fire waiting to happen. ---

yes I was pretty wrong, I am definitely no mechanic. I siphoned the gas out of the intake manifold, and have now ran the fuel line and evap lines correctly. It all runs well and I am super grateful for your guys help. Once you all pointed out the problem, I can’t lie I felt a little dumb. But hey, it didn’t catch on fire, so I guess I am happy!

Check the engine oil level and for fuel contamination. The bottom of the intake manifold has a “belly pan” sealed with a paper gasket, gasoline can seep through the gasket, leak into the engine and dilute the engine oil. Perform an oil change. ---

OMG & Holly Cow!!!, that my friend almost made you a top 10 candidate for the Darwin Award… After I finally got around to watching your video, I about had a stroke… just wow… For safety sake, would you make another video of the current set up?? You thought you did it right the 1st time… As mentioned, you probably have fuel contamination in the oil, gas will wash out the bearings and cause catastrophic internal engine failure, change your engine oil ASAP… Not trying to sound mean or be mean…
