Re: Just did this install

Gene, I just installed my gauges last week. I used the the 45 degree fitting (comes with gauge from Geno's) in the banjo on the bottom of the filter housing, screwed grease gun hose into that.



I was going to add little 1/8" NPT ball valves close to the banjo fittings when I Install my pre- /post filter sensors so if broke, etc, I would have a way to shut them off. I'm just a little concerned about the mass of them and vibration. Has anybody done this, or am I overkilling the installation?

lgould, think a valve is a good move, use www.grainger.com p/n 6MN31. Small, light and only costs $3. 29

I'm hot the person to ask about automotive wiring! T thought wire was wire. I bought copper strand (20 G) at auto parts store and soldered to the silver wires on the guage leads. works fine. I was hopeful someone could explain the difference between AC and DC wire to me.

The difference between AC wire and DC wire would be that the AC wire would be solid and the DC wire would be stranded. I believe that's the difference they're talking about.

I bought my female coupler ar Home Depot. Bled the line by bumping starter and letting fuel spray into old quart oil container . Not sure if it was right or wrong, just what I did. Time will tell with my sender. Working fine so far. Good luck and most of all, have fun! (leaks are no fun, seal 'er up the first time. ) Also... I thought I'd save some $ and buy my wire at HD while there. HD told me to get the wire at auto parts store cuz all they had was AC stuff. Didn't know there was a difference, so back to auto parts store for the wire I went.

There are two stores in my area who will order Grainger stuff. One is an Auto/Industrial Supply and the other is a Mom and Pop Hardware Store. If you have something like that in your area, give them a try.

I was going to go with a mechanical gauge off the bottom of the filter housing. Would the pressure spikes from the 44 give me erratic readings?

Seems like there has to be more to it than that - every light fixture, lamp I have ever bought for the house (110 VAC) was stranded wire and the house wiring is solid. (!?) I went to Radio Shack to get some wire and I insisted on stranded - the kid asked me why I wanted stranded - I told him it was automotive wiring and the stranded is more flexible and withstands vibration better than solid.

What is gonna be the difference between taking the fuel pressure reading at the banjo bolt as opposed to at the schrader valve location, either removing the schrader valve or using an A/C test line fpr a hose to the sender

BK was kind enough to PM me the answers to my questions about AC vs. DC wire. Here is the meat of it. Thanks and credit go to BK, hope he doesn't mind me sharing... .



"So If I wanted to carry lot of current at low voltage, but wanted to make it flexable (not to break under vibration) and high voltage isnt my concern... you may want to call that DC wire..... 12V, 20 amps, multi strand for lower resistance and better flexability, cheaper insulation no UL agency issues.



If you want to carry higher voltages, moderater currents, need to meet building codes... . the wire can make big bends and I have space to working in. . well I can go with a solid strand wire (cheaper to make), but my insulation has to withstand the higher isolation voltages, meet building requirements... ... ... ..... such a wire is one the one would use in their house (AC wiring). "



I'll take that explanation...
