LSPV leak problem on a 86 mighty max

[miked50]

the lspv on my truck just showed signs (again) of a weeping leak after its replacement approximately 5k miles ago....the replacement part is "AKICO" brand (made in japan?)...

some history on the truck:

i replaced the original NABCO 7/8 brake master cylinder with a replacement part master cylinder sized 15/16 due to the unavailability of the required part at that time. plus the plumbing on the replacement part the reverse of the original part. the original master cyl have a rear then front plumbing (if seated at the driver's seat) while the replacement part had a front then rear plumbing. but i connected the brake lines accordingly to the replacement part. can you imagine what i mean...is the master cylinder somehow connected to the problems with regards to the lspv?

sorry no pics for now. cannot find the cable for my phone as of this writing. thanks for your "troubleshooting".

Pics would probably help, leaking from what you put on probably thats the problem.
