did you ground the sender ground wire to the FRAME ?

this will get you a bad over full pegged needle .

also did you swap in a bigger psi / flow pump to feed the higher psi required sniper ?

i did a ep381 acdelco unit direct plug and play swap . worked for my super short run with the sniper and been great with the edelbrock pro flo 4 now no problems .
