Impatient, aren't we? lol I called about 30 minutes ago and am waiting for Alma to return my call. If I don't hear anything today I'll call again every business day until I get my questions answered. I'll post the same day that I hear something.

Regards,

DD

 

OK, here's the deal.

I talked to Alma at Aerocraft and she said the fuel pressure gauge P/N 3-102-50 is 0-5 psi and it's mechanical and you don't need an isolator. I questioned the safety of that application and she gave me the phone number of the manufacturer (UMA) so I could talk to tech support.

I called UMA and talked to Ed Corse. He said planes (ever since the Wright Brothers) don't use isolators and that it's no problem. I said that may be true but I wouldn't personally recommend running a fuel line to the dashboard in a car and wait for lawsuits.

After some helpful discussion he said they could custom make an electronic 0-5 psi fuel pressure gauge (P/N 4-360-005U, 2 1/4") that would need a sender (P/N 1E3) (perfect for 12 V systems).

If they make 1 gauge just for me it would have a basic "computer generated" dial. If we want several gauges made there would be a one-time charge for a silk-screened dial.

I called Alma back to get prices (after Ed gave me "list price").

Alma said the gauge would cost $105 and the sender would cost $87. The one-time charge for a silk-screened dial would be $90 but then, since it would now be a stock item, all future purchases would still just be $105 and $87, including the silk-screened face (her prices were $10 each lower than list).

So you can order the basic gauge and sender for $105 + $87, or we can split the $90 for a silk-screened dial and the above prices still apply.

One note: the gauge does NOT have a light ( 'cause Ed said that would GREATLY increase the price due to aircraft specs).

If you choose to order from Aerocraft (1-866-659-2376) ask for Alma because she's the only one who will know what you are talking about.

I am not associated with either company. I get no commission. I make no warranties either implied or expressed about the quality, suitability, accuracy, blah, blah, blah regarding the above products.

Expensive? Yes. Worth it? You decide. I'm going to buy one.

Let me know what you think.

PS. About the "group buy price". Yes we can get one but I'm too old and pessimistic to be responsible for coordinating the damn thing but if you're feeling froggy, by all means, go ahead.

DD

 

I forgot to mention that to custom make a gauge (Ed said) it will take about 1-2 weeks. To get the first silk-screened dial would take about 3-4 weeks. Sorry I left that out.

DD

 

damn thats expensive. I think I'm going to hold out for a low-pressure diaphragm gauge. I've seen them a few places on the web and e-mailed but got no reply. I'm still looking though.

 

Ok guys, I have some info but with it being Good Friday it will be Monday before I can secure the deal.

I have been able to locate a source for highly accurate low pressure gauges suitable for fuel. These will be offered in 0-5 and 0-10 PSI versions with an accuracy of +/- 1%.

These are not commercial quality 3-2-3% gauges. These are high quality gauges. When the needle points to a mark you will know it is accurate within .05 or .1 of a PSI depending on the gauge range.

We will also have snubbers for the 0-5 guys along with the fittings for installation. We are also working out Dry-Break connections so you can remove the gauge once you have the regulator set.

More info to come on Monday. Price is not firmed up but we plan to be able to offer kits with Dry-Break under $100 and the gauges under $50.

Damn am I ever glad things are moving along

DublyDurty thanks for your research. P/N 3-102-50 (the 0-5psi gauge they have in stock) sounds like it could be good for my use, since I'm not going to permanantly mount it, just temp mount it in the engine bay for tuning.

Which actually makes bwaits' kit sound even better Open hood, snap gauge in, check pressure. Adjust regulator, unsnap gauge, shut hood. Simple, awesome.

Dude, billy if you can make this happen, I'll be top of the list.

Jon

 

bwaits,

That sounds like what I initially wanted! Some kind of "accurate" quick-disconnect in the engine bay. And cheaper than the in-cabin mount.

First no choices, now (potentially) two. Good job!

DD

 

way to go bwaits. Thats just what we need. Keep us posted, I'm almost defenitely in.

 

Good deal Billy...

 

Nordskog Digital Gauge # M8024 + Sender #NRDS8424
(0-16psi in 1lb increments).

I enjoy the idea of the RESpeed kit, too.

That's definately something I'm going to get.

 

and here billy comes to save the day. just keep us posted. im most definately in

 

Okay Billy, it's Monday now.... Where's the update!?!

 

And here we have it.........

Kit 1: 0-10 PSI, 2-1/2" gauge size. 1/4" NPT male fitting. Accuracy listed as "1% full scale ASME B40.1-Grade 1A".

Kit 2: Dry Break Kit with all needed part to fit 1/4" NPT gauge. You can use this kit to set your regulator then remove the gauge for safe keeping. You can use this kit to extend the gauge outside the engine compartment to get a visual of the gauge while you drive the car.

Kit 1: $46.50
Kit 2: $36.50


The 0-5 gauge in this model is not suitable for fuel. 0-10 with a 1% accuracy will work great for carb setups. The face is 2.5" and the pointer will be within .1 of a degree.

-billy

 

Only one question comes to mind:

Is the gauge face marked in tenths, quarters, halves, or whole psi units?

I understand the gauge is accurate to .1psi (1% of full scale) but that doesn't help if there are only marks every half psi. Then the slight inaccuracy of the gauge is compounded by the immense innacuracy of my eyes.

Also, are they short sweep or full sweep gauges?

Jon

 

Gauge face is marked for every .1 of a PSI and is a full sweep gauge.

High quality stuff.

-billy

 

What special precautions should be taken if the gauge is mounted outside? Will it need a special hood (for the gauge, not as in car hood)?

 

Do you mean "outside" as in the engine bay?

-billy

 

I'll see you come payday.

You take paypal right?

Jon

 

Outside as in outside the engine compartment so that it is visible while driving as mentioned in Kit 2.

 

That idea is used temporarily. You would not want to mount it permanently outside the car. I guess you could but........

The gauge can be permanently mounted within the engine compartment. The dry break kit just allows you to remove the "expensive" and "accurate" gauge from the elements, until needed.

I will setup a part number in my catalog. You can paypal or CC on the website. I will order my stock in a few days once I see the demand from purchases.

This is the link for the "fuel" section of our site:

Gauges will be ordered around the end of the month, once we get a feel for the volume of this thread.

-billy

 

count me in. I think you'll get plenty of demand for this. Its nice to have a smaller company that really meets our needs.

 

im in, as already stated. just let me know when you get these. i have some other things i need to get from you anyways.

 

I will be very intrested in it when I upgrade my carb

Thank you!!
