Gauge mounting.

[AmIdYfReAk]

Hey guys,

I'm working on a ole 86 5000 with a friend, and we're looking to mount some 1/8th NPT Gauges on the fuel feed line and the frequency valve but i'm unable to find decent fittings to make that happen.

This is going to be a permanent mounting in the car, its not for one time use.

What do you guys use? I'd love to find a M10 banjo bolt tapped with 1/8th NTP on the back of it and replace the stock hardware...

can you explain in better detail just what it is your trying to do? I know where to buy 12M banjo bolts with a 1/8NPT on the head but I doubt 10M is large enough to do that. I also know where to buy long banjo bolts to "stack" lines but again I am not sure they come in 10M. Explain the idea and reason and maybe you can get some better responses.

I'm not sure how else to explain it,

We're looking to mount a Fuel pressure gauge in two different spots on the fueling system to read pressure.

The Banjos are M10X1, and we already have longer bolts to be able have two banjo fittings on it.

The Current install is rather stupid, We're using a M10 banjo fitting to -4 JIC, Then a -4 Female to -4Female, -4 to 1/8th NTP male and lastly a 1/8Th NPT Gender bit to mount it to the gauge.

The Whole assembly is roughly 1.5' Long ( including the gauges ) and looks stupid.

I've found a M10 banjo bolt with a M10 output out the top from an obscure British website, Then a M10 Brass fitting with three 1/8th NTPs on e-bay... But i still feel as though there is a more fitting solution.

I even remember that VDO had M10 Gauges with extended shafts to read pressure of banjo fittings, but i cant find them, or find a listing for them.

Except for pointing out the danger factor with installing a fuel gauge inside the car, with a direct connection to fuel, I have to ask one more question. For what reason? To monitor the system and control pressure while driving? I guess you could do this as a temp kind of setup for tuning but permanent?

[AmIdYfReAk]

Except leaving out that it was never mentioned that they where going to be installed in the interior of the car, Exempting it from any sort of danger of a fuel fire inside the cabin.

And yes, its for tuning this, as well as using a home made controller for the frequency valve to adjust pressure on the fly ( Boost pending ).

Now that we've got the Why, along with other things aside, lets focus back on the how.

You’re right. That you planned to install the gauges inside the car was an assumption on my part. But I have to point out that my assuming was based on the following statement by you . . .

Hey guys, This is going to be a permanent mounting in the car...

OK, so enough with appears to be a personal problem. The "why" is really not complete as I/we don’t know exactly what it is you want to read. I don’t want to make any more assumptions and cause any more ill feelings. System pressure and control pressure would be my guess. I can't see someone really wanting to watch the needle bouncing from changes the frequency valve makes. If so I need to point out that monitoring system pressure is kind of a waste unless you are watching for signs of a fuel pump failing. Once the system pressure is set it remains so the entire time the engine is running. It might waver a tiny bit with sudden strong engine consumption but will recover in a split second if everything is in good working order. But it's your idea so . . .

Control pressure I guess could be worth monitoring if you have an adjustable system. Even then it seems a bit overkill as once you have it dialed in any minor changes while driving are going to be very slight at best. Control pressure is also what one could call low pressure and does not require the strong/tight connections that system pressure does. The how part will depend on the where would you like to connect the gauge (location)? How much are you willing to spend (tight budget or normal wallet)? There are lots of places to find all sorts of different and one-off fittings, not just Summit or Jeg’s, but one needs to know just what they are searching for, hence the location request. A little bit of detailed information goes a long way towards getting good answers. Just a thought.
