Hello All,

Following advice found here on the venerable BB, I have begun to check the fuel pumps on my fleet of 93's by individually providing power to both the main pump and transfer pump side of fuse 4.

And as you might suspect, I found that on green wagon, the transfer pump wasn't operating. So I secured a "good" JY unit and installed it only to find some 10K miles or so later that the transfer pump was again not working.

So, this time I decided to go with a new Airtex E8778 unit. After installation, however, I found this pump to be rather noisy. Of course, keep in mind that previously the pump was very quiet as it wasn't operating. Question 1: Has anyone else experienced this noisy pump issue? So I replaced it with another E8778 only to find this new unit to be as noisy.

Now onto green sedan a few days later and surprise: that in-tank pump isn't working. So I replace that one with a new E8778 and interestingly there isn't the same bothersome drone from this in-tank pump.

So I figured it's time to check the main pump. Turns out green sedan is drawing 3.4 amps and green wagon is drawing close to 4 amps. Experts have suggested putting a fuel gauge on the rail (I have a 93 which has the Schrader valve) but I almost hate to use the Harbor Freight fuel gauge because it tends to leak making me very nervous.

Anyway, is there another manufacturer of in-tank pumps other than Airtex that BB'ers have had success with.

Thanks for any input as I'm getting awful tired of being "in the tank". Bottom line is should I just live with my noisy pumps?
