My kids 72 IH 345 truck with the new TBI conversion that tuned out perfectly a week ago has been running worse each day. So kid says "I don't know" so we pull it in shop to find out whats going wrong... this filter was one week old. Happens all the time on conversions in old cars, new fuel system keeps gas flowing and sediment stired up and this is another reason you always run a filter before the inline pump.

So you say you made need a filter ay?
