Fuel Pressure Gauge - ZR-1 Net Registry Forums

So I'm thinking about installing an in-dash fuel pressure gauge. Has anyone ever drilled and tapped the fuel rail for a sender? I'm thinking there's room for a sender on the drivers side at the rear of the rail but I'm wondering if there's enough meat to drill and tap at that location.

Why not just hook it up to the Schrader valve?

Well I was thinking it would be nice to still have the option of hooking up a test gauge to the schader valve under some circumstances. Plus a sender at the Schrader valve would be quite visible.

Robert I understand what your doing but are you planning on boosting the car?

GC - I'm sure you meant BOOSTING - guess the "typing assist" got the better of you!! LOL

GOOD MORNING - looks like the Tech1 adapter arrived back to you! Thanks again

That's what I did. IIRC, it was easy to find an adapter. I think my FP gauge's sender needed 1/8" NPT. My hunch is you could find a tee adaptor combo that would allow you to keep the Schrader port.

But, maybe retaining the Schrader port isn't needed if you have a fulltime FP gauge.

Might want to talk to Todd, he's building a custom fuel rail.

It may be better to weld an AN-2 fitting into the rail where you want it, rather than attempting a tapped hole. I would be concerned about a screw-in pipe thread fitting leaking, especially if you don't have full length engagement.

Perhaps a tee is not a bad option, I just had the rails powder coated so welding is off the table now.
