Hi Norm,
Yes Norm there shouldn't be a problem with these new parts but there has to be a reason why the new
caps and needles are leaking.
If it was me I'd be putting all the assembled leaking needles ,caps and floats aside and testing and measuring everything,
comparing them with working caps ,needles and floats to see any differences.
I didn't think you can assemble them wrong Norm as they are new parts as you say but something somewhere must be different
with the caps to get this problem.
I'd be interested in comparing the ones that don't work to working ones Norm ,If you keep the leaking primer caps with
needle and float together.
Cheers
Max.
