RE: How to check fuel pressure at WOT?

So did you use a fuel rail adapter to install the sending unit for that gauge or did you tap into the fuel line somewhere else using a different adapter?

I think I can find a place to hide the gauge, might be easier than trying to use live link.

moose, if you really don't want any gauges and you
really want to know your fuel pressure @ WOT
(for peace of mind), then perhaps data logging with
live link is for you.....

if the pressure DRO..... is fuel pressure (looks like it might be)
then your golden.....

i installed an electrical fuel gauge and really like it, i also know
alot of people like a cleaner, stock look inside the cabin.....

if you need the sct manual...try here

I know there are people on here with electrical fuel pressure gauges. Did you have to buy the fuel rail adapter that's used in nitrous kits and screw the sending unit into it or did you do it another way? To hook up a mechanical gauge i'd still have to buy the adapter plus a shrader valve or hose to screw into it. for $99 I can get a digital gauge with sending unit. Why are analog electrical gauges all $200?I'm guessing more expensive to manufacture.

here's a pic before the wiring got cleaned up, i tapped into the
fuel line as shown below (passenger side).

I saw the one from summit, but wasn't sure if it would work with the pressure we're pushing. Mr. gasket makes one for a bit more that's aluminum.

I wanted to put it under the car somewhere, I'll have to check if all the lines under the car are hard lines. If I put it before the fuel filter is it going to make much difference? I guess I better go change my fuel filter while i'm thinking about it.

I was just going to buy the zex adapter.

I saw someone take out one of the air conditioning holes and put a gague in there. It strangely looked pretty good.

don't buy the zex adaptor, there is not enough
room......the whipple air intake lays right over
the stock fuel pressure sensor.......

the adaptors will be fine with our fuel pressures....

under the car is a unique location.......i don't know what to
say about that......

RE: How to check fuel pressure at WOT?

See, now that is why I was asking. I thought there might be a problem with the compressor and that adapter.

Thanks, i was thinking under the car to keep the sending unit away from the heat, but i'm pretty sure it's all hard lines under there.

I was going to put it in the glove box, but then thought I might actually want to look at it occasionally. I'll find a place. I just don't want a pillar pod.
