GO FAST BITS FX SERIES EFI FUEL PRESSURE REGULATORS JOIN OUR EXISTING LINE OF SUCCESSFUL PRODUCTS, BUILT WITH THE SAME PRECISION, MACHINING QUALITY, AND RELIABILITY THAT IS THE FOUNDATION OF OUR REPUTATION.
From the 800Hp FX-S Street to the 1500Hp FX-R Race version, and whether you run pump petrol/gasoline, Ethanol, Methanol or Diesel, we have you covered no matter what your Fuel Pressure Regulator requirements are.
What sets us apart from the competition? Well, if you’re looking for an EFI Fuel Pressure Regulator that seals and behaves just like your factory unit but with the added reliability and high flowing capacity you require, then look no further than the FX-R.
How have we achieved this? Our engineers have spent countless hours developing a unique replaceable co-polymer valve seat. What does this mean? Conventional aftermarket performance Fuel Pressure Regulators typically utilize a metal-to-metal valve and seat which by nature will not positively hold pressure when your engine is shut down, which can make startup more difficult.
Here at Go Fast Bits, we have incorporated a softer, more compliant yet resilient material for the valve seat, which will always positively seal and hold fuel pressure on shut down, designed to give factory-like sealing and reliable startup, as well as superior fuel resistance suitable for Unleaded, Ethanol, Methanol, and Diesel fuels.
We also use a double layer diaphragm, which means we have twice the reinforcing material, and as a result the burst strength exceeds 1000psi!
The FX-R also offers multiple fuel inlet and gauge ports that allow for a wide range of fuel system setups beyond the usual inlet/outlet, including parallel fuel rail or returnless "deadhead" systems. The two gauge ports allow you to run a mechanical fuel pressure gauge AND an ECU fuel
pressure sensor if you want to.

Nice starter toys
Color: Pink, Color: Pink
Decent rubber toys. You get plenty and each one has a slightly different texture / hardness.
Our 12 week old yorkie pup especially likes the "bean" and the ring.
My issue though is that she is already starting to break the toys and I worry that she might ingest the pieces that come off. Therfore I recommend having an eye on your pup when they are playing.
The bean chewie does a good job at cleaning your dogs teeth. The toys are also easy to wash.
Overall not bad.

Choking Hazard
Color: Blue, Color: Blue
This item is not suitable for puppies. When chewed on pieces of plastic fall off the toys and can create a choking hazard for small dogs/puppies. I had to throw all of the pieces in this set in the trash.

Best small puppy toys
Color: Purple
This is one of the best puppy toy for heavy chewers. I have a 3lb chihuahua who chews as much as my Labs would. The pieces don’t fall apart in little bits and keep her busy for a little while. One of the best parts of the toy was the braided cloth attached to it. The cloth is soft and doesn’t shred like a rope toy so no swallowing bits of rope and no getting nails stuck in rope. I highly recommend these toys for you little chewers!
PS Would love to see if they make any other
toys. Their website is very tiny and has no contact info.

Cute but potentially a choking problem
Color: Pink
My 5 month old miniature poodle actually bit off the little knobs on a couple of these toys. Needless to say I took them all away from her. They are cute toys but not really safe
