New FUEL PRESSURE TAP for GAUGES!!!

[SmithvilleD]

Autometer makes a "snubber' for use with diesels. ON Cummins it's a must have . aLSO IIRC Autometer recommends using an extension hose from tapoint to sender to absorb vibration. I just ordered an Autometer fuel rpressure gauge , and snubber for my cummins.

Yeah, I'd seen AutoMeter's site recommended their snubber on certain year Dodge/Cummins mentioning something about pressure spikes (maybe at startup - can't recall the specifics).

When I've run my 6.5 enough to know w/ certainty this thing solves the issue, I'll put the specifics on what I found & where to get for $4 on the forum. If I can find a pic of the AutoMeter version, I'll compare as it wouldn't surprise me if they're the same part.

Believe it's a simple restriction orifice. Limiting how much of each pulse/pressure peak can get through it quick enough to impact gauge response. More or less slowing up (a bit) how quickly pressure beyond the orifice can equilibrate w/ pressure before it.

I think it's worse on the Cummins. The VP44 runs around 15-18 psi with an aftermarket LP.
Been checking out the Airdog setup and The fass. Other than it won't flow on fail which I have not heard of one failing i wonder how they would work with a 6.5 ?

So as not to further hi-jack Leroy's thread, I'll post my results on the lp pressure pulsation damper in another thread when I've confirmed it works as expected.

Your not jacking, please do post here when you know.
I can say that my needle is steady. I took some more pictures and will post them in a few after I load them up.

These are some different configurations of the FPT

Not a very good picture but you get the idea.

Set up for mechanical gauge. Hose runs off to the gauge.

Set up for electrical gauge. Its not hooked up (just for the picture)

Shows the combo FPT and TBB

This is an air bleed I made up. Instead of loosening the FPT fitting just open the valve and direct the fuel though the hose to a catch pan.

Will that setup (T-air bleed and guage) work with the turbo power cover on it? I am going to put the cover back on my new engine, it looks cool.

From the looks of it only with a mechanical gauge. But, I am only judging by the pictures provided.

3rd and 4th pics are electrical gauge.

Can we tee bleeder with electrical gauge sender?

 

[DieselSlug]

Yeah i want to do the t setup with a mechanical guage... I dont want a pod thing in my cab, i dont know why i just dont like em.. in this style cab.. I put them under my heat/ac controls...

They work great. I'll be upgrading from the Walbro to the Airdog/Raptor setup for my veggie ride. Walbro's just don't hold up to vegetable oil. Diesel, I think is fine.

did this for 25 dollars, need new pic showing cut off to gauge. did notice the lp operation causes slight gauge rattle- annoying after a while. I use this to monitor post filter pressure and lp operation idle to wot. Very impressed with numbers Heath's lp put out.

Ive got 60K miles on my Walbro With WVO.

Yes thats an electric sender and yes you could tee with it also :smile5:

Im not sure? I bet it would if you angled the hose to go back instead of up.

Docdray, what size of hose is that? Thanks.

standard, have not got to do feed the beast as of yet, I think 1/4". to do that mod was one reason I moved the fuel manager. Its a 3/8 T with 3/8 to 1/4 barb
