I dont have a stock fuel system I got the air dog 100
---AutoMerged DoublePost--- O one more thing I filled up the gauge part with liquid silicone but it did spilled a little there were air bubbles on the hoes will that affect the pressure reading? |

The reason why we use glycol or silicon is to use a non compressible liquid in the line. Actually, they will compress, but far less than air. The reason this is done is do that the throw of the isolator is lessened to obtain the same pressure reading. In other words, the isolator diaphragm has to move further if only air is in the line. So, if you are at or near the travel limit of the diaphragm, you may get incorrect readings. However,when air is compressed or a liquid is compressed the end reading will be exactly the same. Remember to always reset an isolator upon an install. Just pull the fitting on the gauge side and gently push it back to the engine side with a blunt object. I like to use a pencil eraser. This gives you full travel. Dave |

isolators to me serve to save the gauge more than anything else.
We get calls every day about how a customer has a gauge rattle. They want it warrantied, but removed the isolator. The isolator serves as a shock absorber for the system. Since most people do not understand how a snubber is supposed to function and or cannot build one of their own, an isolator fits the bill for 99% of the public. A lot of guys don't trust isolators and that's fine. But when working correctly, they do serve a great purpose in the fuel system. In fact, in some areas they are required by law. Dave |
