Holley fuel pump leak

My new Holley 12-360-11 mechanical lift pump appears to leak from the inlet 1/4" NPT fitting. I even resorted to applying PERMATEX LINK HERE since some reading I've done stated that it is compatable with fuel and it could be used on injected cars.

I mic'd the threads on the fitting(s) and have went and bought new ones and found minor differences.

I even read where with a barbed fitting they state to ensure it's long enough to use 2 hose clamps?
Looking back I have had this issue with the older style Holleys (they were chromed and cracked at the inlet) and the 12-360-11 pump I replaced was leaking (I thought it was the diaphram, but now I am not so sure). My buddy the painter told me it leaked years ago in his shop and that he fixed it, I noticed it had what appeared to be that permatex sealant at the threads later.

Are these pumps problematic?

I guess the permatex no. 3 worked after all

Stuff like that with pipe threads will leak if not sealed right. Watch any pipe fitter. I think I went through this with a boat I had. Certainly taught me to check anything out that I did. Especially to the fuel system. You haven't lived until you've seen a race car, coming off the track towards your brand new car, which is sitting on the return road, without you in it, with 15ft. flames engulfing the whole front end! I jumped in my car and split!
