Fuel rail upgrade?

godzilla race works rail that comes with a built in gauge. But after doing some price calculations I’m looking at around 380-400 in total price.

That seems like a lot.  There's really no need for a gauge, unless you plan to change fuel pressure often.  Once you set it it doesn't change.

Looks like they're charging $30 - 40 just to drill and tap a hole.  If you're handy you can do that yourself.

I can definitely make that rail myself, I saw the last thread on making one. I think the rail is definitely an inflated item.

I made one from some inexpensive blemished bar stock.  It wasn't too hard.  I had a drill press and built a jig to hold the bar.

I think it might have been from here.  Still out there.

Edit - not sure if one foot is enough though.  The eBay listing reads like you can only get one foot sections.  Can't remember.  Probably in site's thread.

IMO, the fuel gauge is a real time reference point on how the fuel system is operating.

I agree, it should be a set and forget item but it is nice to have for roadside diagnosis or just making sure the pump and FPR are good

[Zed Head]

It's definitely a real-time reference.

Once I got my Z problems all sorted out I barely opened the hood more than once a month.  And that was only to check the oil and coolant reservoir.  So, it really depends on where you're at in your project.  I also had found a Schrader valve T'ed in to an Isuzu fuel line in the wrecking yard.  So I had a Schrader valve for measuring pressure easily.  Many different ways to do things.  You can probably find electronic methods today and have a gauge in the car.

I remember looking for one of these  in a junk yard and finding one. I balked when they called it a "fuel rail" and wanted a bunch of money for it. They were used on the Rodeo SUV IIRC. Do you remember what year range these came from?  I can't find the info on it any longer.

You could get a tee like what @Patcon linked and buy a schraeder valve to go into it. https://www.summitracing.com/parts/ear-9616sverl or https://www.amazon.com/Earls-9616SVERL-Male-Schrader-Valve/dp/B01EKUFV90

I agree with Steve but for $25-30 you can buy a complete fuel pressure kit on Amazon. Tee included...

The Isuzu valve was nice because it was all one piece and the metal tube is 5/16" / 8 mm.  cut the tube and slide it in.  I posted a picture in a previous thread.

I can't remember the year, I think it was late 80's.  Unfortunately, not really common to find them in the yards.

I was browsing pictures of a new BaT Z and found what looks like an FPR that holds pressure.  Might be worth some research.  Picture 114.
