fuel tank question

[vansite89]

which fuel tanks will fit on an rd other than the rd style tank?

the mounts are the issue. the front non strap tank mount is unique to mack. you need to use more traditional style mounts if you go with other tanks.  you could also go to mack square tanks but again the mounts are different

so if i were to change the mounts, coukd i install a cl/granite style tank?

One thing to keep in mind is where the front j bracket mounts to the chassis could be on the flared section. Meaning if you bolted any normal J bracket on there it could be crooked.

yes if you have free rail space to locate the new tankmounts. the front frame rails start to spread near the cab cowl so make sure you take that into consideration . also some air tank brackets may be in the way?

My R-model (frame rail shape is generally similar to a RD excepting the heigth and thickness) has all the tank brackets of the J-style including the front ones. But when you investigate them removed it could be found that the J's themself are almost simiar but the front brackets which attach the J's to the rails are made shorter (less offset to the outside of the truck) and slightly tapered to be fitted onto the rail's side which spreads at the front section of the chassis. So no use of a general style intermediate bracket from common rear tank mounts.
