Engine/Transmission (1994 - 1998) Banjo bolts

[TSPowell]

I keep seeing these "high flow banjo bolts" for sale. That really seems like a waste of money. Im thinking about taking my Dremel and making the holes larger. Has anyone else done this?



Also, what are the banjo bolts torqued at?

 

[Diesel Gunner]

Yes, it is done quite easily. Do not overtighten when reinstalling. They can be broken if overtightened and then the fun begins. I have drilled out and deburred several sets and have had no problems.

I managed to twist off a Geno tapped banjo bolt. They have some specific torque specs for you, but I think mine had a weak spot. I can tell you that they twist off VERY EASILY! Geno's was good people and gave me another one free of course.

Time is money. They break easy. Break your Geno's bolt, you got your stocker to fall back upon. Break your stocker... .

Edit, they work for 12V's too.

The weak point is where the two cross drilled holes weaken it so much. If you were just wanting a pressure guage connection, you could drill small cross holes and strengthen your own bolt a lot. I am so spooked by the first one breaking, I fear failure of the bolt from just heat and vibration and have not reinstalled it.

A better improvement is to eliminate the banjo bolts. I don't remember the part numbers but I'm sure someone will. Larger hoses and AN fittings are available at reasonable cost. I think I paid less than $50 for mine.

 

[Jim Fulmer]

If your going to change the line out you will need (2) fittings, a M12x1. 5 to a 6AN and a M14x1. 5 to a 6AN, then 2 6AN 90's and some 6AN line. It's up to you to decide on the high pressure blue line or braided steel line.



The M12 goes in the filter housing, the M14 goes in the pump inlet!

I re-drilled (can't remember size)countersunk, and reamed my bango's a few years ago. I might have seen a 1-2 PSI fuel pressure increase at the P7100 inlet. I just did the fuel filter head and P7100 inlet banjo. Is an easy job.



Kind in mind Joe Donnelly made 799HP w/ the OE un-touched bango fittings on his '97 12V.

And NO ONE here remembers THIS thread:



CHEAP and easy fuel flow improvement! - TDR Roundtable



Drilling and carefully reaming and cleaning the OEM banjos is hardly rocket science, and EASILY within the grasp and ability of most truck owners - and while some material is removed, it would take an extremely inept installer who VASTLY over-torques them to break one during re installation. - and for that matter, I sorta doubt the aftermarket ones would be any less weak in the enlarged areas.



As to power levels with opened banjos - I recently made the power levels displayed in my sig with what I've done to mine - and as pointed out further above, others have made considerably more even with the stock ones.



Sure, you CAN spend the $$$ for fancy fittings and the upgraded lines to connect to them - OR use your own common tools and get a high percentage of the flow increase for a fraction of the cost.



BUT, for sure - if you can't use a drill or a wrench properly. better get the expen$ive stuff - and pay someone to install them for ya! :-laf
