Does anyone know where or what type of hose I can use from the engine to the dash to measure fuel pressure. I was using 1/8 plastic hose but need something better.

Alec,
I dont know about a marine application, but in most car racing sanctioning bodies, that is a big NO-NO. Autometer has a fuel pressure gauge with an isolator that mounts at the fuel pump/engine end of the line and then a line with a inert fluid in it that runs to the panel area. Only thing is I am not sure if they make one with a line that is long enough to run in a boat.

Not sure if anyone makes an electric one or not. I personally would not want a pressurized fuel line running up to the dash panel, especially a plastic one. Does the CG allow any thing like this at all ??

Thats just crazy !!!!!!!!!!!! Go out and buy a marine fuel pressure unit before you kill your self or some body else. That is just so wrong !!!!!!!!!!!!!!!!!

go electronic, no fuel under dash

What he said! You would spend more on reliable stainless braided hose to get it to the dash than a new electric pressure gauge would cost. Even with the SS hose you still have the chance of a fitting leak....

wait untill JAN. - FEB. and i will have a new Gaffrig mech. fuelpress gauge with everything incl . for dashmount.

I will do the same thing in my raceboat ,because its the most accurate thing to have ,, mech. Fuel, Water and Oil press. !!

You can also call Mike or Marc from GAFFRIG Performance .

My gauge came with 1/4 " marine fuel hose to the gauge.

That's not crazy its just a question to get some right or wrong anwsers and get the most correct fuel pressur reading. Alot of boats have this set-up ,thats just stupid to say that your going to kill someone or yourself. Just think whats underneath your seat maybe a fuel tank ? What if the carb line starting leaking and hit's the coil ,and many other possible problems that can happen . I guess these are all Crazy things that can kill. I know they make electric sending units , But come on it's not cool to come off like that. Like I said it's just a simple question either good or bad. Peace

You would have to use USCG approved fuel line. I doubt you will find it in that size. It is not worth the risk. Put a mechanical gauge on the engine and run an electric gauge to the dash.

Livorsi has a fuel psi sender and gauge that pretty accurate if your trying to get dead on you'll have to use a shop gauge at the engine.
