AV gas transfer pumps, flow meters, and UL 2085 tanks – a quick guide

istock_000008983874xsmallWe have had some very good questions come in worthy of posting on our blog.  So, if you are distributing Aviation fuel (Av gas) or perhaps you are serving a small airport;  you may find yourself asking what is so special with regards to avgas pumps, flow meters, filters, and so on.

Let’s start with the basic question, what is Av gas? In simple terms, it is a super high octane fuel to power many aircrafts.

Wikipedia gets so deep into this definition so if you have the time, read on here.


Next, two very important questions?

1. Can I use any flow meter for Av gas?

2. Do I need an interior lining for a UL 142 or UL 2085 storage tank?


700_rotary_meterLet’s answer the first question:  can I use any flow meter for Avgas? No, you cannot use just any flow meter. Why? Av gas is a dryer fuel, the meter needs to be equipped special bearings – so when you call us, you need specify a SPA (Standard Petroleum + Aviation Gas).  That is truly the only difference but it needs to be specified.




Now, to the next question.  Do I need any special lining for AVgas in a UL 142 or UL 2085 listed storage tank?

The answer is, it depends. Lining a tank for AV gas is up to the end user. A liner for AV gas is not required but most customers want the option.  So we give you the options.

Last, we have been asked if a UL 142 storage tank is needed, or perhaps a UL 2085 storage?  Well, that question will be best answered by your local fire marshall or local authority, so please check with them.  We will be happy to email you spec’s and general arrangement drawings for final approval.

Either specification, the UL 142 or UL 2085, the tank interior needs to be buttwelded, sandblasted and lined for Jet Fuel.

The last part about fueling a small aircraft is to ask if your customer will be doing it overwing or underwing.  The following video demostrates an overwing refueling process.  The underwing set up creates a lot more pressure and requires a very different connection.  Make sure that is clearly specified.
