Ds4 fitting for fuel pressure gauge

[Will L.]

Have him post pics of how the adapter and sending unit fit in there.
The crappy intake manifold on hummers/ van is way worse.

I’ll ask him when he texts me how it ran. I think he took the family to the beach after he installed the new sender in the tank.

Long term the one leroy sells is better- but pricey. But the new one should last for 20 years- that was pretty bad after just a few

OK we installed the gauge on the ‘94:

He’ll get around to permanently mounting the pod. Used the “T” fitting from Mod Mafia.

Do you have a link to that?

That was the link, but here in different form:

Sorry, thought you were referencing the youtube video link.

Cost for the fuel pressure gauge set up was not bad.

Gauge: $89.99 for the analog only version, includes sender. It jumps to $129.99 for the analog plus digital. Never have been a fan of digital.

Gauge Pod: $12.99

Mod Mafia T fitting: $30

Colby did the install. I'm waiting to hear back how it's running after he changed out the fuel sender/pick-up in the tank. Sender was very corroded after just 4 years in there, thought it sat for 3 years with a full tank. It seemed to be running well, this on Marty's IP, but until it's road tested......

Is this the correct size for the DS4 pump, then @Will L. ? 6AN?

 

[DieselCash]

If that one works, I could use it.

 

[DieselAmateur]

The DS4 inlet fitting isn't -AN, it's a 7/16 ORB fitting if memory serves. It screws into another larger fitting on the pump that I think houses the inlet screen. So you'd need the 7/16 ORB on one end and -AN on the other if that's the fuel line you're using

We need a definitive parts list with links for installing a fuel pressure gauge.

Kind of like the Feed the Beast instructions.

I have a small pile of parts that I hope has everything I need. If I ever get to work on the truck again

Fuel Inlet Upgrade for DS Pumps

DS4 injection pump 3/8" fuel supply upgrade. This replaces the restrictive factory 1/4" inlet fitting that screws into the regulator assembly and allows you to run a new, larger, fuel supply line directly to the injection pump. Now featuring 100% aluminum construction! Our adapter fittings are...

That's the one...a -an/jic fit's it, or get a barb to slid a hose on and clamp...

 

[Will L.]

Im not the guy. I give away every ds4 & pmd I lay my hands on.

DB2 gang for life YO! . Much easier for us with either 5/16 or 3/8 npt fittings.
We add a piece of stainless steel tubing to get out from under the intake manifold and have a T fitting right there where the ffm used to be. I used to fender mount my ffm in pickups. The older trucks that had the rectangular filter - that got thrown away and mount spin on filters set up on the fender.

Will didn't mod mafia or someone on the Hummer forum sell one for a ds4?

 

[dbrannon79]

On the IP the threads under the factory barb fitting is 7/16 orb. you can sub a -4 an male as it uses the same thread and the flare end won't contact anything threading in, just put an o-ring at the base of the male thread. -4 to -6 an hydraulic adapter will work and use gauge port adapter. once there you will need to have a custom fuel hose with the female -6 an or another adapter to barb fitting to use the rubber hose.

 

[Will L.]

Yes Mod Mafia was selling one- it was female flare: male flare w/1/8” Female npt for the sensor. It was for the FTB modded units that have the larger size. Idk if they are still selling them or not.

 

[MrMarty51]

I ordered the feed the beast kit from Leroy. It came with the ORB to AN fitting that accepts 3/8ths hose barb to AN.
I then ordered the male to female AN fitting that has the 1/8th” pipe for the sending unit.
