Overview

The Aviation Consumer, Product of the Year. JPI’s FS-450 is our top choice because it has all the options you need for fuel management.

JPI’s newest piece of panel wizardry relegates fuel-situation questions to relics of the past. From its new home between the top row of flight instruments and the top of avionics stack, the FS-450 blinked and winked the numbers to answer all my fuel-situation questions.

Connected to our Honeywell Skymap IIIC, the FS-450 happily winked and blinked its way through its information inventory and left me as relaxed as any fat-dumb-and-happy aviator should get — minus the “dumb” part of the equation, of course. Heavy-duty information and a light-duty price; could you want more? Sure, easy installation would be nice, something JPI also covered.

Features

Fuel Used (USD):
How much fuel has been used since you last refueled. This number will always become larger as fuel is consumed. You can instead show the fuel used on a long multi-fuel stop flight and we will see later in this video how to do that.

Fuel remaining (REM):
How much total fuel remains in the aircraft. Only total fuel remaining in the aircraft is calculated.

Hours and minutes remaining (H.M.):
Based on the current fuel flow rate, displays the remaining endurance time. This parameter is most meaningful during cruise. During sea-level climb the fuel flow rate will be almost twice that of cruise and the endurance indication will be about half of actual. On the other hand, during a power reduction descent, the endurance will indicate more time than is actually available when flying at cruise power.

Fuel Required to Waypoint/ Destination (REQ):
This parameter will be displayed only if your EDM is receiving flight data from your GPS (this is a standard feature which is included with the Fuel Flow option). This will tell you how much fuel is required to get to the next waypoint or destination programmed on your GPS, based on your current fuel flow rate and present position.

Fuel Reserve (RES):
Fuel reserve when you arrive at your next waypoint. This parameter will be displayed only if your EDM is receiving flight data from your GPS (this is a standard feature which is included with the Fuel Flow option). This will tell you how much fuel reserve you can expect when you arrive at your next waypoint or destination programmed on your GPS, at the current fuel flow rate.

Excellent product with easy install! Can’t put into words how comforting it is to know exactly how much fuel is available. Everything in aviation has come a long way since 1955 when my Tripacer was certified, the FS-450 brings the fuel management into the present century!

Display on my FS450 was erratic, sometime shutting off in flight despite good wiring and volt supply . Just ordered this brand new one to avoid workshop trouble shooting on a 15 years old display . Plug and play OK . Hope this display lasts at least 15 years. I appreciate FS 450 accuracy . A real need in managing and monitoring fuel on my IO550 V35.

Purchased an additional $300 in parts, installed in about 7 hours with 2 people. Works as it it should. I have not had it installed long enough to test accuracy . I’m very happy with the FS 450 and it sure makes you lean it out!

Fast and easy to buy online with Aircraft Spruce. The Alaska store needs more staffing to be more efficient. They are always pleasant but they are slammed.

As of today I have not been able to get the FS-450 to work. After the install and it didnt work I contacted tech support who made me feel like I was some kind of ignorant moron. There suggestion was to blow through the transducer to see if the pulse wheel was spinning which it was. So what now? Well you can call the RMA department and get an RMA to send it back to be bench tested, DUH! After 15 emails back and forth with JPI RMA department I finally got the RMA and sent the transducer back. Im currently waiting a reply. Needless to say Im not impressed with JPI, especially Tech Support, and will not be doing business with them again.

Works like a charm. Accurate and reliable. A&P quoted 8 hrs for the install and paperwork. YMMV.

Best upgrade I did for the plane. When coupled to a compatible GPS it provides a great sense of fuel quantity situational awareness. Itll let the pilot know if there is enough gas to make it to the next waypoint or not. Well worth the price.

Great little instrument. This was a plug and play no fuss replacement for a Shadin instrument that wouldnt work with a new transducer. Very user friendly menus.

This thing is worth its weight in gold! Makes leaning the engine much easier and much more accurate than 50 year old fuel gauges with bouncing needles.

One of the best STC'd add on's you can put in your aircraft. Extremely accurate fuel flow monitoring unit. Working perfect in a Robinson R44RII.

Please note that this gauge will not fit in a 3-1/8 hole. the box is too big and interferes with the mounting screws of the 3-1/8 hole. 3 stars for now as its not working yet!

Push buttons fail. Only way to repair is to buy new unit. I have seen this happen on many units - same problem again and again.

I received the new FS450 out of the box with a non operative 231 Transducer. As usual, Aircraft Spruce passed the problem to me. I was forced to purchase a new transducer and wait for a bench check of the new/old unit. The non working unit showed up magically working after 2 weeks. JPI has a QC issue from my limited perspective. All works fine now but it seemed a bit much to get a new unit in operating condition.

I purchased an FS-450, when I powered it up for the first time, a portion of the display did not work. I contacted JPI, who want me to send the unit back, pay a $150 testing fee to diagnose the brand new unit and told me to expect it to take 4 weeks to get back to me. Although they said if I pay them $100 extra, they would put a rush on it. Seems like quality control issues at JPI, and definitely some serious customer service issues.

Q: Does the JPI FS 450 GRAVITY FED (P/N: 10-00134) come with a FAA FORM 8130-3?

No, these do not come standard with an 8130-3 form. These must be requested at the time of order.

Q: Does the JPI FS 450 unit include the transducer?

Yes it does as you have to select gravity fed (231) or fuel pump (201) system.

Q: I just purchased a 1966 Piper PA28-235 with no current fuel computer system installed. What else do I need to order with the JPI FS 450 for my mechanic to install the system?

Please note that the FS 450 cannot be used as a primary fuel flow in your panel (in can be used for secondary). The JPI FS 450 comes with all the parts to install the FS 450 but other parts like tubing and connections from your fuel system need to be ordered separate. We recommend you and your mechanic review the manual on our documents tab before ordering to make sure the install is efficient.

Q: What is included with the J.P. Instruments Fuel Scan FS450? Is it compatible with a Cessna 182R?

Items included are the indicator, fire sleeve, harness, transducer and pilots guide. If you want to use it with your Cessna, you will need to use the gravity fed version (10-00134).

Q: I have a Cherokee 180 and wanted to add this to augment my fuel gauges. Can I install the FS450?

The manual describes the procedure for installing the Fuel Scan FS450 as a secondary gauge including the necessary placards you must include with the installation of the gauge.

Q: Which J.P. Instruments Fuel Scan FS 450 would work on a Cessna 150M?

For a Gravity Fed Fuel aircraft such as the Cessna 150 series you would need part number 10-00134.

Q: Does the FS450G have the flow labelled in Gal/Hr on the gauge, or is the label units/hr?

The JPI Fuel Scan FS450 is programmable to either gallons, pounds or liters.

Q: I have the EI Red Cube transducer fitted. Is that compatible with the JPI FS 450?

The recommended transducers are listed for the FS450 in the installation manual by JPI. Using another manufacturer’s transducer is not recommended or tested.

Q: Is there a wiring harness available for the FS 450 transducer to indicator?

For the fuel scan FS450, part numbers 10-00135 and 10-00134, the harness is included with the instrument.
