That would be for a different problem... Filler neck/fuel cap wont cause fuel pressure to drop off...Nd4SpdSe wrote:Could be as simple as the fuel cap? Filler neck leaking too maybe? I had to replace mine because it was rusted and leaking (bad spot for snow and salt to sit where it was ) Or maybe just the seal around the fuel pump/sending unit is gone?
correct...That would only be during cranking, and would have no effect if it was done prior.
