i just bout one and cant figure out where to put the sending unit on my 91 teg. can anyone help me? last gauge for me to hook up! i dont wanna be one of those guys with a nice gauge and it aint hooked up. thanks guys

 

where on the fuel rail do i hook this thing?

 

I had a B&M gauge that fits on top of the filter, and used the 90 degree angle that came with it... you should be able to go to Home Depot and get the fitting - bring the sender with you and match the threads... it will repace the bolt on top of the filter. Easy way to get it done.

 

It's a piece of ****, mine almost caught on fire If you don't need it, don't use it.

 

sorry i wasnt more specific in my first post. its a 2 1/16 autometer ultra lite electrical gauge. mounts inside the car with a sending unit to be connected to motor and plug the wiring harness in. its not one of those gauges that mount in the engine. its in my pillar. hth me.

 

1.) You can use a fuel rail from STR, AEM, DC Sports, etc. with a 1/8" NPT port already tapped into the fuel rail to mount the sending unit. This is what we'll be doing on the motor we have. But, if you don't already have one of those fuel rails, they cost upwards of $110....more money. Altho, if you bought a $190+ elec fuel pressure gauge, what's another $110?

2.) You can mount it in place of the B&M mechanical gauge with the included 90 degree 1/8" NPT fitting. But, you'll have to buy the $30 kit....not worth it just for a couple of fittings. If you already have teh B&M, it works out pretty well.

Or, you can try to find a M10?x1.00 metric (or is it M12x1.00?) to 1/8" NPT adapter, and then buy the 1/8" NPT 90 degree fitting. You have to have the 90 degree fitting otherwise the sending unit won't clear the hood.

3.) You can use a 1/2" or 3/8" ID inline port in the fuel feed line. They're like $6 from Summit Racing. The port is 1/8" NPT, so you can just thread the sending unit into the port. But, given that I really don't trust these things not to leak at the kind of fuel pressures associated with fuel injected engines and that the fuel line probably routes under the intake pipe (where you won't be able to routinely and easily check for leaks), I wouldn't recommend using it.

If you care to spend the time to peruse through the McMaster-Carr catalog, you can probably find what you want at a low price.
