Where is the best place to tap into a 426 street hemi to run my 1/8 plastic oil pressure hose. I didnt see any plugs to remove behind the intake like on my 440. This thing is a whole different animal that im not used to. 69 1/2 A12 BEE 4 spd 1968 Charger 383 1970 Roadrunner 440+6 Survivor 2019 Redeye 2005 FORD GT Red/White 2017 Viper ACR Extreme Red/White 1979 Branco Red/Red 2018 Porsche GT3 Miami 1971 440+6 Cuda 4 speed V2 2020 Sebring Orange Vette 1979 Chevy Boogie Hippie Van

I would upgrade to a copper tube versus the plastic tube though. Stan there should be a plug right next to the factory sending unit. If its anything like mine, it's next to impossible to see behind the intake. You really have to jam your head back there to see it.

Use a length of #3 AN line that Auto Meter sells. It already has the proper ends to adapt to the gauge and the block fitting. They can be purchased in a few different lengths. You can also go with a modern electrical gauge setup. I find them to be pretty accurate as well. If you have never seen what 80 PSI of hot oil will do to your engine compartment(or worse yet, your interior), you don't know what ugly is. MB

Just put a new pressure gauge on my '70 Satellite and used copper on the advice from my Father-In-Law who had the plastic one melt on him. Yuk. Good luck on the resto.
