This is how to change the fuel pressure regulator on a Chevrolet 3400 SFI V6. Mine was leaking internally and was causing a thick fuel smell to be present in…

Great video. Would’ve never figured out the tool sizes on my own. Worked on
my 2001 impala. Thanks!!!
i have the same problem on my malibu 2001 v6 can this turn on codes in my
car
The correct size wrench for the reg. is a 24 mm, not the 1516 standard.
How do you get the wrench on the fuel pressure regulator fitting?
why are things never as simple as you think. There is no way i can operate
2 15/16 wrenches like yours in that space, Very frustrating.
Need help my throttle is in the way and I cant get the tool to the fp reg.
Same van don’t know why mines a little different. Took a pic and it looks
like mine are closer together.
it only has 1 injector?
Thank you so much for sharing this video!
Thanks A LOT!! You’re the first person to say what tools were needed and
the sizes. Even though it’s not a Monte Carlo you showed me how to do it.
Thanks :-)
Just change the fuel regulator great video man
I just grabbed it with a vicegrip on top of the torque screw mount and held
it in place from there. i only had 1 15/16ths wrench. Thank you for
posting this video it was helpful !
this is a bitch to take off personally 1995 buick century fpr is bad gonna
do it on sunday
Thanks for the great video and for being specific on the tool sizes!
It would be easier to use an angle or L-shaped connector on the pressure
gauge but I managed to use a straight connector by flexing the engine mount
to the left a little while attaching the connector.
To check fuel pressure, look behind the power steering pump on the other
side of the engine (passenger side). Even the chevy venture manual has an
incorrect drawing. It’s very difficult to connect a pressure gauge because
of the very limited space.
Crowfoot flare nut socket would good for taking that thing off if it was
seized on there from rust. I would take the line nut off first, then the
torx screw last to avoid needing 2 wrenches. That torx screw and clamp is
strong enough to hold it in place while breaking the line nut loose. I’ve
done it on an impala. Also have to floor the pedal so u have clearance for
the torx screw.
Mine was just loose so I just had to pull it out of the fuel rail and put
it back in and tighten it back up. BTW mine was not a T40 but instead was
an Allen head.
Thanks a lot that fixed my problem. You guys was a big help.
Nice video, thanks!
I just replaced mine in a 95 monte carlo LS 3.1 yesterday. Besides the
smell of rich gas, I had problems with cold start. The first time I’d start
it for the day or after it sat for a few hours. It would crank and crank
but no start. Occasionally backfiring in the engine compartment or out the
exhaust with a small puff of smoke. After changing the regulator it starts
up with no problems. There’s also the obvious signs of leaking gas around
the regulator.
2005 Venture. Had to jam a stick on the gas pedal in order to rotate the
throttle out of the way to get more room. Used two short length wrenches.
Used one wrench to undo the fuel connection. Keep the bolt in for last. Had
to slowly pry the reg out of the engine. Gently pull the fuel line up in
order to thread the nut on the new reg. PCV line very brittle. Broke mine.
Use both wrenches to tighten fitting.
This was a huge help. Thank you so much for posting this video
other than the smell of gas, what other problem would it cause to indicate
this was bad?
