Merry Christmas
Yes i did have a gauge hooked up. 30lbs psi with vacuum hooked uo 40 with out. it will sit and idle for a few minutes then guage will show loss of pressure and it starts to stumble then stall at 0.
then when you immediately try to start it it starts right up. fuel pump was replaced 1 yr ago
I did make a short video but its still to large to post
