"I have been plagued with a number of new tanks that are somehow contaminated causing the screens to get clogged up. For one customer I went through 3 tanks and destroyed 6 pumps. Temporarily install a tee and vacuum gauge on the pump inlet and see what you have after a drive. You'll know if the tank is the problem." So I bought a vacuum gauge and am ready to install. When I drove the van the other day the fuel pump was almost completely silent for an hour or so of driving, then finally started buzzing. To check on a clogged fuel tank it seem like I'll have to leave the vacuum gauge installed between the tank and pump as I'm driving. I just want to verify that that's the idea. There's no indication that the gauge is designed for measuring liquid vacuum. Since I have no idea about the internals of the vacuum gauge it seems like fuel could go into the gauge and possibly leak out. |
