Fuel Pressure Gauge Questions.

Ok, Im gonna need a fuel pressure gauge here soon, and I was wondering which one you all use. Im gonna need something from 0-15 PSI, preferably white face black numbers in half or quarter pound incriments. So far, the only two I see that I like are the Summit Racing Gauge (and I dont like the "Summit Racing" plastered across the face), or the Holley. The problem is that I dont know if I should get a dry gauge, or a liquid filled. I know that liquid filled dampens vibrations and prevents premature failure, yadda, yadda, yadda. The question is, is it necessary in my application? I dont have some modded cam engine with a lumpy idle etc. I just would rather buy the dry Holley gauge for $24.99 over the liquid filled for $39.99 if I can. If its gonna be a bad decision in the long run, I can get the other one, Im just wondering.

So, to shorten all that down, heres what I wanna know:

1. What gauge are you personally using?
2. Should I get a dry or liquid filled gauge?

Thanks everyone .

PS - Here are the gauges I was looking at getting (scroll up after you click the links to see the specs of the gauges):

1. Summit Racing Liquid Filled
2. Holley Dry
3. Holley Liquid Filled

Sorry I don't have much advice on the gauge, other than I would probably go liquid-filled.

I don't know if you've seen this, but it' a cool way to tap your fuel line.

Cheers

Yeah I have seen that at Summit Racing . The fuel pressure regulator Im getting has outputs for the fuel pressure gauge though, but thanks anyway .

Well, those are good points, but I will need it when I get the Weber thats coming installed... I gotta get that fuel pressure regulator to the right pressure somehow, and guessing doesnt seem to be too popular .

personally, i'd like to order the Yaw gauge... but i cant seem to get in contact with the man to order one... oh well.

right now i've got a $7 Autozone 0-15psi 1/2" gauge that's working... and it seems to almost read accurately, or at least shows me how much i'm raising/lowering the pressure... whether or not the readings are correct.

Wha?? That's not something you hear everyday about YawPower...

The liquid-filled gauge is to prevent the needle from bouncing as you try to read it....with a smooth rotary, this is not a problem....

You only need a liquid filled gauge if it sees a lot of pressure spilkes (if the gauge is mounted to a fuel rail close to the injectors)

if you are running a carb you won't have these pressure spikes to rattle the gauge apart (unless your pump has a lot of pulses and the gauge is mounted near the pump)

my vote, get the dry gauge and pocket the extra $

TJ, don't waste your $$$ on those crappy 0-15 psi, "look at me Im a cool super tuner gauges". they are inaccurate as hell. You dont need to have one under the hood all the time do you?. If your serious about tuning your fuel pressure get a REAL gauge. Make a setup that allows you to remove and install the gauge for testing. As always PM me for pics Go search mazspeed. I posted a link to surplus gauges that blow those summit pieces'o' junk away. Accurate, huge faces, easier to read graduations. Oh and i didnt mention......cheap. Like $7. If I didnt have a yaw gauge I'd get one of em. Hell for the price I might get one anyway!
