Fuel test port removal.

[x MadMAX DIESEL]

Posted this on df with no replies.



Just wanting to get a little statistic here. Those of you who tapped into the fuel line through the test port or schrader valve for a pressure gauge.... Did you end up snapping the aluminum shaft off, or successfully unscrew it? I've snapped one. Now I have a new one on the motor and I'm almost scared to try again lol. Do you think I can?

You can do it, put your back into it!

I'd just hate to snap it again!!

I have broken two of them, after that I used a small propane torch, havent had an issue since

I snapped mine, so I just drilled and tapped it for 1/8" NPT

my schrader valve (test port) is leaking, any other ways to remove or plug it

 

[408.Luke]

If the valve itself is leaking you can replace just the valve or take the valve off and cap it. But like previously said, its easy to break the fitting off the block

So if i take it off to cap it is it a standard pipe thread or something special ? Just wanna get what i need before I take it apart .

 

[408.Luke]

Not sure what the thread is, ace hardware by my house did have something that fit it, just dont remeber what it was.

I just ordered a adapter fitting from all season diesel. I'll try it with a torch. Last time I just ran a machine screw down in it after it broke for about 6 months lol.

I broke mine off when we were installed the twin piping. Welded it shut until I bypass it.

Don't most people remove the restrictive test port block and run fuel line directly from filter head to CP3? At least on the LB7.

I don't see how that will really be any less restrictive. I know a lot of people do that. But you still have the restriction of the orfice on the cp3 inlet fitting.

I want a gauge as close as 6 inches to the cp3 inlet as possible. But don't want a sensor in a soft line. So this is the happy medium for me.

Thats why i buy the big 1/2 inch and 3/8ths parker fitting and drill them out just a touch.

The best thing you can do is run 1/2 inch rubber fuel line right from your lift pump to a fuel block in the motor compartment somewhere,mine just floats right behind the 2nd cp3,i used the summit or jegs blue anodized fuel block 1/2 inch in and 2 3/8ths out and its taped for 1/8th inch pipe thread in the top of it where i installed a 0 to 30 psi fuel gauge then run 3/8ths to each cp3 where i have the 3/8s parker fittings.I have no problems with fuel delivery. PM me you # and ill text you some pics of my set up.

Thanks I always like pics! I plan on doing that next year. This year I have enough stuff to get done before the real season kicks off!

idk if you have seen that before or not. why not just put the adapter into the filter head bleed screw and put the sensor there? i guess i just dont understand why you want it so close the the pump.

 

[x MadMAX DIESEL]

I already have a pressure gauge hooked up there.
