i dont know if this has been said before or not, but ive seen a lot of stuff where people are looking for 0-5 PSI fuel gauges. i found two sources:

http://www.aerocraftparts.com/ItemFo...?item=3-102-50

and

yawpower:
http://personal.riverusers.com/~yawpower/access.html

yaw power is for rx7s anyways but the first is for aviation use and i dont know if itd be usable for our automobile use. i emailed yawpower asking about the gauge.

one question i have though, that i also asked in my email to yawpower, is which would be better a gauge in the engine bay or in the car? im am probably like most of use, id rather not have fuel in the car with me incase of a fire. thats why i was thinking insolator. would a 0-15psi gauge be accurate when using an isolator tohugh or would it still be off? some dont want to use the isolator as they arent as cheap as going with just a gauge in the engine bay. id like to be able to monitor my fuel while driving though.

i have been debatinga nd looking for a while and i think ive finally found a series of gauges i like and that have all the gauges i want to run. i ant to do everything right and i think itd bother me not having all the gauges the same series. well heres a link to the gauge and all i was thinking of:

any input is greatly appreciated. thanks

 

Well, I wouldn't take a mechanical fuel pressure guage into the cabin. If you wanna do that, I'd use electrical. Of course, good luck finding a 0-5 psi electrical one.

 

thats why i was thinking about using the isolator to eliminate the fuel being in the cabin

 

Not sure how the isolator works but if it achieves the same result, go for it. One thing for sure is delicate gauges have problems staying accurate when mounted in the engine bay due to vibrations, heat and whatnot. So if you can avoid it, that's even better.

 

aws140,

I'm looking for this too and checked the same links as you did (among others).

The first link "says" 0-5 but the picture shows 0-50. I tried to call a couple of times for verification but couldn't get through.

I also sent an email a couple of weeks ago to info@yawpower.com (I think that's what it was??) and have not yet received any reply at all.

I ordered the "Sterling carb" from Carl and he said he can't find the 0-5 anywhere either. He said to at least get a 0-15 psi gauge to get you "in the ballpark".

btw. I just planned on putting the gauge in temporarily until the pressure seems to be set correctly, and then remove it. If that's wrong, somebody please let me know.

Thanks,

DD

 

An isolator uses something like a diaphragm and a stable liquid on the other end of the diaphragm (usually antifreeze). It's just something to prevent any gasoline or volitle fluids to get into the passenger compartment. If you want to run a mechanical FP gauge into the cabin, that's the only way to go.

Dubly,

I would just leave the gauge in the system. You can use it to see what your FP is if you have problems down the road. Besides, if your pump craps out on you, do you want to find out what happened the hard way?

 

Yaw's gauge may be best (I emailed him for one already this week and have yet to hear back), but I don't know if he still carries/stocks them.

He has stopped making the carbs for people so I don't know if he still sells the gauges.

whenever I have posted looking for one, I was trying to find *another* source for them than yaw, 'cause back when he was making/servining the carbs still he was said to be almost impossible to get ahold of!

I'm still trying to get one from him, haven't heard back from my email, but if anyone else finds another source, let me know.

I think the plane gauge is a typo, 'cause the gauge shows 50, but the title shows 5. *could* just be representative picture, but best to check.

Yaw is notorious (at least in my eyes) for not returning emails, and everything he sells is overpriced (once again, in my opinion). Good tech though.

Anyway, I used a 0-15 PSI under the hood and it worked fine. There are times that I wish I could have been monitoring it as I drove as well, but I never did anything about it. I always kind of like the Aussi 1st gens that run the gauges out on the cowl by the wipers too, that would be kind of cool.

yeah I emailed Yaw too. I'm guessing since he doesnt make the carbs anymore he's probably not checking that e-mail address. It's been over a week for me so I doubt he's either around or answering. I'm running out of time and might just have to settle for a 0-15psi gauge, but after reading all that info an Yaw's site, I really don't want to. If anyone has any success getting a 5psi gauge, please let me know

go there. that shows all the gauges offered on the aviaton site. i looked and the 0-50 is in all the pics of fuel pressure gauges.

lovintha7---what do you mean find out the hard way? id rather have the gauge so i can monitor my FP as i drive. i dont see how itd be a big deal versus it being under the hood.

i too am running low on time. i need to get this together before i bring my car out and i dont want to buy a 0-15 gauge when i know it wont be accurate.

 

I called the Aerocraft folks today to ask about the gauge (Part # 3-102-50). The lady I talked to (Debbie) said all their "techs" were away at a "Fly-in". The person we really need to talk to (Alma) won't be back until April 13th.

1. I want to verify that in fact it is 0-5 psi, not 0-50.
2. Can it be used in cars (not jet fuel or whatever)?
3. Is it mechanical or electric?
4. If mechanical, is the isolator included?
5. If electric is it 12v?
6. Do they offer a "group buy" price? (I'll ask the manager; Robert Williams)

Anything else I need to ask?

No that sounds pretty good.

I'm actually going to email CyberDyne to see if they can make me a digital one. They're pimp with stuff like that.

 

Keep us informed everyone, I'm after a couple also.

 

Well cyberdyne told me that I should just order their 0-16psi

BECAUSE! Its a digital display, so I always have a nice big number staring at me. It would be stupid for them to build one smaller just to take away 6-16psi

 

But how accurate is their digital gauge, will it really show 4lb as 4lb

 

Theoretically, it should

I like all of their other products

 

Did you read the article referred to earlier?

I don't know man... you go ahead, but I'm going to continue to try and find a mechanical dial gauge with a small range. I just trust it more.

Jon

 

Digital is fine, but what if you want 4-1/2 psi, does it default to whole numbers and simply round up or down?

 

i have someone who said they think they can get 0-5 gauges. ill keep everyone posted.

 

It's not 0-5, but check out http://www.nordskogperformance.net/ they have electrical pressure gauges. Just a wire running from the sender (sold separately) to the gauge. They have digital and analog style. Is anyone familiar with this type of setup? Would it be accurate enough to bother with?

Summit sells them too, for less money.

 

Go to the performance section in auto zone they have them already mounted on a T fitting for 19.99.

 

are they accurate?

 

doubtful. You get what you pay for.

It's hard to be accurate with such little pressures.

On FI cars, where you're aiming for whole numbers in the 40s, it's not hard. Whether you run 44.3psi or 44.8psi you'll never see the difference.

But a difference of .5 psi at pressures as low as we run (2-3) can make a HUGE difference.

We need it to be accurate at least within .1 psi. I need to look at the gauge and *know* for a fact that if it reads 2.4psi, it's 2.4psi exactly. That takes a precision instrument, and when you consider that the "19.99" you're paying for the gauge has to cover not only the gauge construction, but the packaging, shipping to the store, the store's markup and any advertising done by the company, you realize how much the gauge itself is actuall worth.

I'm not usually one to say "expensive means better" but when you come down to it, where can you find a company who can make a quality, calibrated precision instrument for $5 (the cost of the gauge after all the other crap is deducted)?

Jon

 

It's for carb setups, so I'd assume it's accurate enough... Not like you need it within a .10 psi incriment anyway. IMO buy the cheap gauge, spend your big money on other upgrades.

 

well it the 13th. any answers yet?
