Hey there, sorry if this has been covered, but has anyone added a fuel pressure guage to the oem rail? this shouldnt alter the flow or hurt anything correct? i was planning on putting it to the left of the feed port? any ideas or pics of it doen would be great

 

Just drill and tap

 

Indeed, I simply drilled and tapped also. I would HIGHLY recommend a liquid filled gauge though, as this is my 3rd Autometer gauge (under warranty) in less than 2 years. The vibration causes the gauge to fail (no longer reads 0psi when removed!), at least on this gauge.

 

thanks guys!!

 

Hm I've wanted to do the same but use stainless lines and a remote fpr and aftermarket rail. Is there a way to convert the oem line to 6an?

Not trying to hujack I'm sure someone knows

 

do you guys have problems with any leaks?

 

i'm wondering this as well.. i bought the PROsport gauges and the the Sender unit goes somewhere and you hook up one wire to ground and one wire to the gauge inside the car... just dont know how to get that sender unit hooked up!

 

If you tap it right, and use thread sealer, it shouldn't.

 

any one with a DIY?

 

If you really do require a DIY for this, here is one.

1. Take off the rail from the car.
2. Drill the rail, its wise to predrill a smaller hole before going to the intended size. Using a pillar drill is making it all easier.
3. Thread the hole with a screwing tap.
4. Clean away all unwanted material that possibly went into the rail when drilling/taping.
5. Use thread seal or teflon tape and seal the threads of the device you mount on the rail.

Done. Not very hard huh?

For a car with the pressed plate rail, I would do the same up to the drilling part but instead of tapping, weld something onto the rail. The thickness of material is low in this case. Heres an example of welding stuff onto the rail. There is nothing magical about the fuelrails they are just pieces of metal. Just be sure to clean it well after modification.

The aluminum rails are trickier to weld as you need a TIG with AC current capability, they most often offer the material thickness for successful drilling/tapping.
