There is excitement at Randy’s Garage when packages with this logo arrive!

Here is a closer look at the unwrapped parts.
I ordered mine with a black face (no surprise there!)… it also comes in white. Interestingly enough the gauge is a “Marshall” – the name of my third son!
I plan to install this kit tonight! I’ll keep you posted on how that goes!

Bonneville Performance Oil Pressure Gauge Kit Installation Update
With the Bonnie safely raised on a floor jack, I removed my seat, side covers, gas tank and carbs to give me ample room to work.
Getting ready to remove carbs.
Next, I loosened and removed the stock banjo bolt and crush washers.
Banjo bolt and crush washers
I carefully cleaned the area around the hole on top of the crankcase.
Banjo bolt and crush washers removed.
Following the Bonneville Performance instructions, I stacked the new crush washers and fittings from bottom to top as follows: new crush washer, OEM hose banjo fitting, new crush washer, BP kit banjo fitting, new crush washer. Through the center of this stack I inserted the new hex head banjo bolt supplied by Bonneville performance, and hand tightened it.
Stacked fittings
Following this I removed the two engine case bolts where the oil pressure gauge bracket mounts. I used an 8mm socket wrench.
Engine case bolts
The new bracket is mounted on these two holes with new, slightly longer stainless steel 5mm hex head cap screws and washers. I hand tightened them at this point.
Hand mounted oil-pressure gauge and bracket.
Next, I connected the supplied new hose from the banjo fitting on the crankcase, to the fitting on the back of the gauge. I used some Teflon tape on the threads, and hand tightened only.
Inspecting the fit with hand-tightened fittings.
I now made sure everything fit well with no kinks or misaligned parts. Everything looked good so I tightened down each fitting as directed in the instructions, being careful not to over-tighten.
I re-installed the carbs and gas tank, and then fired up the engine.
Once I determined that there were no leaks, I installed my air cleaners, seat and side covers.
The new Bonneville Performance Oil Pressure Gauge registers in the 20-30 lbs. range at low idle (1,200 RPM), and jumps up to around 80 lbs. at 2,000 RPM. I love the look of the liquid filled black face and feel more confident now with the knowledge of exactly what my oil pressure is doing!
Checking for leaks – none!
Do you ship to India. I need an oil pressure gauge for my 2015 bonnie se.
Vimal, I do not sell the pressure gauges. This article is about my experience installing a pressure gauge I purchased from Bonneville Performance. You can order them here: https://bonnevilleperformance.com/product/oil-pressure-gauge-kit/ or use their contact form to find out about shipping costs to India. Good luck!
You’re a god amongst men. Thank you for writing up this clear tutorial. I’m also installing the same unit this weekend. Safe riding!
Great to hear, and I hope that this article helps with your install. My oil cooler kit is still going strong, with no failures!
