Pressure senders and gauges

The sender is calibrated to the gauge it is serving, so it's unlikely the readings would be accurate.

It would be unprofessional and unsafe to run the fuel gauge in the passenger compartment. Most racers put them on the engine or on the cowl.

Why not just use a standard pressure gauge for testing?

W-W-HAT?!!!!!

Get your Attention Deficit in order here, bub. Tell us WHY it would be unsafe? Hint: Subject of the thread.

As an ENGINEER but NOT SAE or mechanical but also a guy who has seen a few oil senders spring leaks... I'd say Okay. NOT permanent... or ShurzHell - eventually you will Fiero.

It'll only be good for looking at "delta" of course.

Accuracy is not my concern. It the change off of the normal value. Once i establish what the nominal value is. When i have my intermittent condition, i need to see if the pressure is dropping.

You did not read my post very closely. I said ELECTRIC sender. not MECHANICAL gauge. (remote reading, no piping of gas) Therefore, any gauge in the passenger compartment would be electric, and there would be no chance of fuel leakage in the passenger compartment (which would NOT be good) This would be a temporary set up anyway. Just for testing purposes. I have a intermittent condition which maybe be fuel pressure related. I don't want to have to stop the Truck and pop the hood to look at a mechanical gauge when it happening..

I don't own a high pressure gauge for FI systems at this time. Its on my list though. If i were shrewd, i could temporarily disconnect the oil pressure senders feed wire and replace it with the temporary fuel pressure sender and use the dash OP gauge for read out. It reads up to 80 PSI or so. It Should be in the ballpark for readings That's assuming i could plub the sender in. And i get a second sender that's close to my current oil pressure sender in function At this

point, i am still studying if that's feasible in my S10.

I still don't understand why accuracy is not a concern. If for example your standard cruise reading was 10 psi and during problem X it was 9 psi. since the sender and gauge are not calibrated to each other, you would have no reference point as to what that meant. It seems that you are trying to make a complex solution for a simple problem.

You are correct. I actually did not read it incorrectly. I interpreted it incorrectly. I was incorrect in understanding what you meant (which is what you said :)).

You don't have to pop open the hood. That was my point. Technicians have been tapping fuel gauges to windshields for dynamic fuel pressure testing for at least 20 years. This was the point of saying,

I never thought of using a A/C gauge. Very original idea. But you could never use it for A/C uses again due to contamination. I only have one right now, but i periodically run across some older beat up ones cheap. Maybe the next garage sales i will pick one up. What is the female fitting called that screws on the end of the shrader valve and depresses it?

If I bought all the right tools, I'd be in debt to my eyeballs and panhandling for food money. I don't think it's possible to own all the right tools unless you're Bill Gates. :)
