Yes about 2 seconds I’d say. Thing is before the dorman gas tank I was running the tank out of a 98 camaro which was the donor car I had it back of the bed ran fine but not safe so I switch to a dorman gas tank for a 87 r10 with a built in sump so I know the vats cant be the problem. I’ll have to check with a fuel pressure gauge like you said. Thank you!
