WLb30p Posted February 20, 2010 Share Posted February 20, 2010 Presently have a wet type air cleaner directly on top of the carburetor. The cleaner's oil sump bottom is rusted thru in many locations and won't hold oil, and I don't have a replacement cleaner. Will be replacing the cab shell with another cab which had a diesel engine and an external wet type air cleaner(in good condition) on the passenger side. If I switch over to the external air cleaner, will there be any adverse restriction on air flow due to the length of tubing going to the carb, that affects engine performance? What kind of connecting "tubing" might I need? Any thoughts on switching over to a dry type air cleaner either directly on top of the carb or in the external air cleaner?

The EN-331 engine does not have the capability to flow the amount of air a diesel does. The choice of either staying with a carburator mount air cleaner setup, or external would be up to your personal preference. However the B series cab would need the hole in the cowl both under the hood, and in front of the windshield filled if you used the carb mount filter assembly. If you use the external type, you could use most any type tubing but I would suggest pipe easily allocated at truck parts stores for turbocharging applications. You would need to adapt it to fit the carburator air horn with a boot that steps down in size. This is not difficult to do and most any local truck parts store should be able to help.Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

Packer Posted February 20, 2010 Share Posted February 20, 2010 You might also look at using Fiberglass to repair the stock air cleaner.Keeps the stock look and easy to do!acker Quote Keep a clutchin' Link to comment https://www.bigmacktrucks.com/topic/12728-air-flow-restrictionen331gas/#findComment-50012 Share on other sites More sharing options...
