Al, I know that = my fuel pressure sensor was originally specified for oil and they said to just = use it for fuel.  I would imagine that there is not much difference = between oil and fuel as far as diaphragm tolerance.

That’s kind of what I = figured also.  But I seem to recall that in the descriptive for an oil = pressure switch I was looking at it said “not for use with fuel”, = which got me wondering. I’m not so concerned about a malfunction because it = can be checked every run-up by turning off the primary pump, but I don’t want a potential = leak.

 

 

Also, check out = this great selection of fittings I just found.  I wish I had them long = ago, would have made my sensor installation easier.

 

 

What a great site for = fittings!  Especially now that all our plumbing is completedJ
