Double Bajo Bolt

As my fuel line exits to top of the final (engine mounted) filter on my Perkins 6.354, there is a unique looking 90-degree banjo bolt. One side feeds the injection pump and the other is the return to the tanks. The fact that it is 90-degrees greatly interferes with the bolt that removes the filter. Since I am overhauling the whole system anyway, I would like to change it to a better configuration.

Is there a version where the ports are 180-degrees from each other?
If not, can I replace it with a stached double banjo bolt?

Thanks,
Tom-

Tom,

Are you saying that the two lines that leave the Banjo com off at 90*.*

Never seen a double Banjo it would be a leaking nightmare.

RE: Double Bajo Bolt

Here is a picture. Upon closer inspection, I have found out the hole in the bolt portion to be a mere pinhole. I assume it's because diesel fuel is so thin compared to brake fluid. I'm wondering if double bolts for dual carb engines would work. However, those bolts will be flowing a fair bit more fuel than I. Maybe not the best idea.

Anyway... Picture ---

RE: Double Bajo Bolt

Tom,
That looks to be part of a CAV fuel filter housing. I suspect the bolt you are struggling with is a 1/4" bolt (uses a 7/16 wrench). The banjo fitting sits right above it and one of the tubes covers the head of the filter bolt as I recall.
The Lehman uses a set of CAV filters (Baldwin # BF825), I remember where Keith posted pics of his "upgraded" fuel filter conversion. As I recall it is a spin-on filter from his pics. This upgrade should work for your filter housing, eliminating the need to access the 1/4" bolt head.

Oh... That would be sweet! Any links to the conversion?
