Guest P15-D24 Posted December 12, 2011 Report Posted December 12, 2011 On the passenger cars a short rubber flex line is used between the oil gallery takeoff and connection to the oil pressure gauge line. When if pulled my truck engine last week it had a long hard feed line (coming from the second most front oil gallery plug) to the hard line for the oil pressure gauge with no flex line. The parts book shows a flex line, but in looking at the pics in Bunn's book the examples he shows are identical to my truck. Any of you trucks have a rubble flex line in the oil pressure gauge circuit? Quote

Merle Coggins Posted December 12, 2011 Report Posted December 12, 2011 Mine is all hard line with a splice joint at the firewall. Merle Quote
carl b51 Posted December 12, 2011 Report Posted December 12, 2011 My oil line is just the same as Merle,s on the parts truck and on the one that I am working on. Carl Quote
greg g Posted December 12, 2011 Report Posted December 12, 2011 Well I placed a vote for flex line before I realized your were talking trucks. Perhaps it not as much of an issue with the way the truck mounts the bellhousing to the frame rails rather than the rubber mushrooms on the cross member. Does that mount allow the rear of the truck engine to move as much as in the car, or is the car more fexible as a nod toward comfort over utility. Quote

The truck engine has the same basic donuts the car has they are just in a different spot. The bellhousing bolts to an L shaped piece which goes in with the L piece upsidedown. Under the little side of the L is a rubber donut mounted to the frame. You can see the two holes the rubber mounts go in towards the top of this. Quote
Dodgeb4ya Posted December 13, 2011 Report Posted December 13, 2011 Only 1/2 through 1 ton Dodges, 1948-53 use rear rubber mounts! 1-1/2 ton up are bolted solid to cast frame brackets rivited directly to the frame. Quote

Any of you trucks have a rubble flex line in the oil pressure gauge circuit? The more steel lines you run, the more "trick" and simple your engine compartment looks, IMO. The only rubber connections necessary are the flex fuel line between the pump and frame line, and of course the coolant hoses. With good tools (and that's the key here), you can plumb with steel tubing all day long. Edited December 13, 2011 by John-T-53 Quote
