Where does the fuel pressure guage go into? I have to buy a 1/4 inch inside diameter braided fuel line but where does that go? Does it go to the top of the fuel filter? Also where does the transmission guage plug in? Thanks

 

Don't know about the fuel gauge. I put my trany temp. pick up prob or sending unit in my new PLM aluim. pan very near the top mounting flange. Did this about a yr. ago, works fine for me.

I got a high flow tapped banjo bolt and put it at the vp-44. That way I know what is happening at the pump.
For the tranny, I got a cross over line from an earlier model truck
(Dodge part # 5011244-AA $106.00). This line is the hot oil to the cooler and is what you want to know. Or you can put a "T" in that line and put your sensor there. This line is located on the passenger side and goes to the cooler. The line you want is the one closest to the fire wall.
Hope this helps.
Good luck.

 

Sender for trans temp can go either of two places-
1) In the pan. Many aftermarket pans have a threaded boss for this purpose (my Mopar Performance did). This gives the temperature of the oil as it is supplied to the clutches, bands, and TC.
2) In the line going to the cooler. You can either use a tee with a couple of compression fittings, a line from a pre-'94, or an aftermarket line with the location for the sender (may even be another option for your 24 valve, somebody jump in here). This location gives the temp coming off the clutches, etc. and is generally considered more useful.

For the fuel sender, best to get a tapped banjo bolt for the filter outlet side. Run a short pressure line from there to the sender (~12" or so). That way, any pulses feeding back from the injector pump are dampened. If using a mechanical gauge, better use an isolator so in the case of a leak in your line, you don't pump fuel into the cab(!).

 

what is a tapped banjo bolt and where can I get it? Do I have to special order it or will autozone or napa have it? Does this bolt go into the top of the fuel filter? Anyone have any pics. I'm still pretty confused!! Thanks

 

Get rid of your banjos and go with braided line from the tank to the filter and then from there to the pump way better fuel press also put a pusher pump in also helps the cheap dodge lift pumps out thats what i did and works great no probs yet anyway

 

What is the reasoning for the banjo fittings on the fuel lines? Where can you get fuel lines that will match the thread pattern of the banjo's? Is the thread pattern standard npt or -an or something else?

Thanks

Take a look at this:

"what is a tapped banjo bolt and where can I get it?

A banjo bolt is a fuel line fitting consisting of a hollow bolt with cross-drilled holes. It goes in an eye on the end of a line and allows fuel to flow through. A tapped banjo has an 1/8"npt female thread in the top that allows you to hook up a line to the sender/gauge. Many in the "vendors" section can fix you up (Rod @ Wildcat for one).

"Does this bolt go into the top of the fuel filter?"

Yes. The filter line to the injection pump.


"What is the reasoning for the banjo fittings on the fuel lines?"

Commonly used in industrial applications, banjos take up little room while allowing flow to change direction 90 degrees.

"Where can you get fuel lines that will match the thread pattern of the banjo's?"

See above.

"Is the thread pattern standard npt or -an or something else?"

In this case, metric straight thread.

Note: If you're going to make big HP, then the restriction in the stock lines and banjos might be of concern. However, for light BOMBing, consider a line replacement kit as $ you don't need to spend.

 

If I were to get the larger banjo bolts how many do I need and where do they go? I plan on hooking my fuel pressure guage line into the top of the fuel filter. Is this where the banjo bolt goes? What should I get other than the whole fuel kit because thats like $130 from wildcat. Thanks

 

If you do the banjo bolts you will need 6. One on both sides of the lift pump, both sides of the filter, and the ones at the vp-44. I think that will cover it. They changed filter housings in 2000. You can mount you gauge line on top of your filter. The banjo bolts are what hold the fuel lines on. You won't need them to install your gauge (pre 2000). They are good for the lift pump because they are not as restrictive as the stock ones.
Hope this helps.

 

I ran my pressure gauge off of bottom of fuel filter
no problems 40000 miles. P/S Isspro EV Series Mechanical.

 

Do you have a 12V or 24V Cummins? Your sig say it is a 98', so I suppose it could be eigther one. I have a 12V, and I installed a Prime-Loc re-locator. I installed two mech fuel gaugaes in the fuel filter mount, they monitor pre/post filter pressure. I use it as a tool to help with reguard to fuel filter flow, when there is more then 1 psi differance between in and out pressure I change the filter. If you have a 12V, I would not monitor fuel pressure in side the cab, we do not have the same issues that the 24V'ers have(problems with faulty lift pumps). And I am not a big fan of having fuel routed thru the cab. Yes I know they make Issolators, but unfortunitly most do not spend the extra money to install one.

 

I have a 24 valve. I don't really mind the idea of having fuel in the cab but how should I seal the threads? I heard Teflon(sp) was bad so should I use liquid pipe thread stuff? Thanks for the ideas on where to put the fuel pressure. I think I am going to put it on the front port that is post filter that way I can monitor my fuel filter. Thanks everyone.

 

Permatex #2 is the best for sealing threads on diesel fittings.
Any auto parts will have it.
Be careful not to overtighten any compression type fittings, they will leak. Tighten by hand then half to one turn with a wrench is plenty.
