[DeTomaso] Pantera low fuel pressure indication

[Mike Drew]

Hi guys,

Getting my Pantera ready for Monterey.  It received a new fuel tank a couple of. Moths ago and was started for the first time and all seemed well. After sitting for a month it was very hard to start, requiring multiple manual injections of gas into the carb.  Eventually it started and continued to run, and revs happily in neutral to 5000 rpm.

But at idle it registers somewhere between 0 and 1/2 psi of fuel pressure. At 3000 rpm it goes to about 2 psi. 

Besides the obvious (bad fuel pump) what could cause such a thing?  There are no indications of a leak anywhere. The tank has five gallons of gas. I have two fuel filters, one of them mondo sized.
