Anothe fuel pressure gauge question

Posted

For 99 owners, where did you tap for your fuel line to gauge. My filter housing doesn't have anything on bottom to tap into like Mike's does. All I have on filter housing is the inline from the lift pump and the out line to the IP, both are on top of the filter housing. Also there are 2 capped ports on top, sorry no pics right now. Is the out line to the IP where I would thread in my tapped banjo bolt for the fuel line. Also, is it okay to run braided line all the way to mech. gauge, don't want isolator. Plan on doing the needle valve setup. Will braided line go into the gauge, i.e. will it thread into the port on the gauge itself, or do I have to do the nylon tubing kit. Thanks.

Might even be able to bleed it by just turning the key on and energizing the pump. Mine usually goes upto 15 psi for a second when the key is first turned on. Maybe you keep 24 seconds of fuel. LOL

Hmm, that might work too lol. Wasn't sure how well it will hold that pressure after that 1 second goes by.

I never worried about bleeding the line but you can of you want. But over time you'll get air bubble back in the line from doing other fuel system work...

So how did you install gauge without isolator? Did you just connect both ends, and it gets enough fluid in the line to give an accurate pressure reading? It seems to me that with the gauge end of the fuel line closed off that fuel would not be able to get to the gauge needle resulting in an inaccurate pressure reading. I've never done this before, so don't know how it all plays out. Thanks.

I would bleed it if it were me. I'm sure it will kinda bleed itself eventually but I would rather remove all doubt lol.

I agree bleed it, if you don't, you might just as well put in the isolator you don't like, because the air cushion in the line is going to make it inaccurate any ways.

Remind me to drill and tap those 2 test ports on mine :lol3:

Alright I had to figure out the workings of my fuel heater. Never looked at it much. I don't know anything about what yours looks like so I wouldn't know. I'll take a good pic tomorrow and we can compare and see how identical they are. I bet there is something different. Dang, sorry bout the mud, melting snow and gravel roads :lol3:
