Lol i was about to go NO! thinking you meant mechanical. I dont see why it wouldnt work but theres always the issue of A) plumbing it in and B) finding a gauge that has like a 0-30psi sweep rather than 0-75 or 90.

its a digital numerical display, gauge starts at 5 goes to 80psi. plumbing it in wont be a problem for me. im just going to have to solder a wire to the sending unit to ground it. cus normally it gets grounded through the block.

Which gauges are you looking at that the fuel pressure gauge is pricey compared to a oil pressure?

by the time u get the fuel pressure gauge and sending unit to go along with it fuel pressure(at least in the range i need) gauges are around 200, oil pressure digital gauge with sending unit included is around 60. at least from what i found. the styles i like.

Wow, that certainly is a "pricey" difference! The only problem I can see is if the sending unit for oil pressure isn't fuel resistent. Some o-rings that are used in oil systems deteriorate rapidly when they come in contact with fuel. Which brand are you looking at?

http://summitracing.com/parts/CYB-A010E160Y/ this is the gauge i used if neone is interested then i used http://summitracing.com/parts/MRG-2975/ this to plumb it in, used high pressure hose clamps on each side of it, not the clamps that come with it.
