Is there a access panel in the trunk to get to the fuel tank sending unit, kind of have a leak in the return line, and I don't really want to drop the tank if I don't have to.

No, it'* not for the sending/pump unit. You need to drop the entire tank. You may also need new bolts, threaded anchors, and straps. Not a big investment, the parts are relatively inexpensive.

If there is one what is it for if not for the sending/pump unit? Ya I was afraid that I was gonna have to drop the tank

There is a panel there, but it'* not above that unit in a way that would permit removal of the sending unit/pump. I'd have to check to see if it would allow enough access to repair a leak or not. Or you could. I'd rather not un-seal my access panel without a good reason.

You may be able to lower the tank just enough to repair something on the outside, but in the long run, you should check your fuel pressure. Your car is old enough that your pump may be weak, so you can combine this work with a pump replacement.

What is the fuel pressure specs for the 93seei? Do you have any preferances in preasure gages?

The Actron gauge is readily available at most auto parts stores.

Your fuel pressure should be 41 PSI MINIMUM at idle. It should hold pressure for several minutes after shutdown. It should rise to at LEAST 43 psi at idle if you pull the vacuum line off the FPR. Anything lower than these numbers can spell doom on even a stock L67. Running lean under boost can be devastating.

Thanks for all the help will
