Senders, Senders, Senders

:lol:

ok, well Im really close to having everything figured out now, but I just wanted to run a few things by some of you to make sure im gonna get the correct part, basically just the senders.

If I go with an Oil Press gauge, I have the choice between a 0-75 and 0-150 PSI sender. Im assuming our pushrod V6's will never seen excess of 75 PSI correct?, thus making the 0-75 sender the one to get.

Fuel Press gauge, I currently have one, but I will be selling it off if I decided to go to another brand. If so like above, 2 sender choices, 0-75 or 0-150.
Im fairly certain ill be going with the 0-150 sender on this one since Ive seen 65+ PSI many times. Just wanna double check on that

Last but not least, EGT gauge. The senders are basically the same except for the wire length. Choices are 6', 10' and 14'. I quite certian that 14' is too much but im not sure if 6' is long enough after routing it over and through everything into the interior. Is there any drawback to going with a 10' wire or is there no problem other than stuffing the extra wire up under the dash.

thanks for any input, its greatly appreciated.

Anything around or above 75+ psi is going to really wreak havoc on your turbo oil seals so I sure hope that you aren't going to run more than that.

There are alot of choices out there as far as gauges and senders. I would be looking for a gauge that has a DECENT sweep to it, some of the auto meters have only a 90* sweep. Making reading them a real PITA. With that said, I'd look for one that has a FULL FACE SWEEP. I think (could be wrong here) that they call them a 270* face. 270* meaning the total angle the needle can sweep. Anyhow its easy to notice the difference if you have them next to each other. I wouldnt recommend the smaller sweep face. I also would NOT suggest the 150 psi sender as its doubtful that unless you plan on running some insane boost levels, that you are going to see fuel pressures that high. Also, I know it has been done on various trucks, but most of the time when you reach 75# psi of fuel you are either running the fuel pump too hard, or there is another problem. I cant imagine if you have a decent displacement pump why you would need to see fuel pressures above 75psi.

Here's what I would suggest, plan out where you want to run those wires and what routing you intend to use. Then get a small length of kite string (or equivalent) and you can tape that in the same general area you intend to run the wires. I had an egt probe in my stock manifolds, I chose to run it off the passenger side manifold near the turbo inlet (exhaust gas inlet) you'd be surprised how much wire that routing can eat up. The best part is/was it looked totally STEALTH and it couldn't be seen since I ran it through the stock looms etc. Obviously if you are going to patch into the drivers side you wont need as much. Also, you are aware, for accuracy's sake that you shouldnt SHORTEN OR LENGTHEN the wires. They are calibrated for the length of wire that they are shipped with. Adding or subtracting wire will cause erroneous readings. As always, YMMY and good luck.

Thats what I figured, just wanted to be sure

No sweep for me, im going with digital readout FP gauge like I have now, just perhaps changing to a different brand, not 100% sure yet. Either way, the pressure information has been noted, thanks.

yeah, i already read the PDF file on the gauge both about its capabilities and the warnings about screwing with the wire. I'll try as you suggested. I guess Im most likely going to put the probe in the downpipe close to the turbo, since thats where I have seen most of them. Either that or ill see if I can get it in the collector just before the turbo like yours was. thanks once again.
