Just wondering, I have heard some stories of them breaking and was unsure if they were true or not.

 

Anyone have any comments on it ?

 

I have had my B&M FPR and my gauge for about 2 years now. No problems so far...

 

never had problems with them. only time I have seen them fail is when they are run in combo with a FMU

 

I have heard of people having issues under boost..is it because of the FMU?

 

yeah with the FMU fuel pressure rises above 100psi and this ***** up the B&M gauge. another for the fmu

 

Mine broke on me. I was running an FMU.

 

So fmu will basically ruin it, nice info. Anyone else ?

 

If you peg it, you'll break it. I've done it before on accident when I had a vacuum leak, didn't know it, found and fixed it, but forgot to decrease the rail pressure. It pegged it when I started the car and from that point on, it wouldn't read correctly or steadily.

Will that happen to any gauge ?

 

The only thing I've heard of going bad on the B&M's is giving weird Fuel pressure readings

 

I'd imagine so, to a certain extent.

A friend once pressure tested his charge and intercooler piping with 50psi of line pressure coming out of the compressor and it pegged his mechanical boost gauge. It read slightly off after that, but it wasn't permanently damaged to the point of not even moving smoothly with pressure transients like my fuel pressure gauge.

 

I've got two mechanical fuel pressure gauges. One on the fuel filter and the other on the fuel rail (AEM). The one on the rail reads about 2psi lower than the one on fuel filter. That seems like an appropriate amount of pressure drop.

 

I had one on my accord. Had to replace it twice because it kept giving me fucked up readings. Replace it with a liquid filled gauge and youll be fine. The non liquid filled gauges seem to not be able to take the vibration from the engine. You can find the liquid filled ones just like the b&m ones on http://www.summitracing.com for like 20 bucks.

I was looking at the autolink one, seemed pretty good. But then I got a deal on a b&m but I might stick with autolink, thanks for all the help guys. Any other people that want to chim in feel free.
