I have the same housing but if I drill it to size the hole will get into the mounting hole for the housing bolt Last edited by 69hemibeep; 12/16/20 04:01 PM. 1969 Hemi Roadrunner 2nd owner

The two 5/8 holes are heater hose nipples the 1/4 is plugged and the 9/16 has a large mechanical water temp sender in it. 1969 Hemi Roadrunner 2nd owner

[/quote ] That would work if I change all my gauges to match, I can look into that but I was hoping for an easier less expensive route. 1969 Hemi Roadrunner 2nd owner

Use the 3/8 NPT for the Sniper sending unit. You don't need the mechanical gauge anymore since the coolant temp will be on the hand held. The temp gauge in the dash will be your backup.

Now I will order the in tank fuel pump kit for the Valiant. I was thinking the jeep would get the Sniper if this didn't pan out. Thanks for the input Last edited by 69hemibeep; 12/17/20 02:28 PM. 1969 Hemi Roadrunner 2nd owner

The handheld display will show you the coolant temp so you don't really need two temp gauges. The hand held also shows you air temp and barometer so it is a built in weather station. If you bought a super sniper then you can see fuel pressure and oil pressure too. On my car I got rid of the stock dash and installed a Holley Pro Dash.
