In Line Fuel filter

[Shugalou]

Hey guys

In an attempt to adjust my brakes I wanted to start it up and put it in reverse, but the truck isn't starting.

I check the filter in the carb and there is a spring and a cap in there but no damn filter...why the PO left that in there is beyond me.

The PO put an inline filter so I replaced with a Gold version from napa and now the motor won't fire over.

I'm wondering if it's possible that the filter material is too dense and isn't designed for a carbed motor but a FI setup? Anyone have any thoughts...I'll probably put the old filter filter on to test out theory just want to hear if anyone has any knowledge on this.

Thanks
