You might want to check the fuel filters in the tanks, may need cleaning as well.

They'll be a filter in each tank. Drain the tanks, then, there are two drain plugs, one inside the other. The smaller is for draining. The larger, basically a large nut, is for accessing the filter. You'll see the filter, and just pull it out. These tanks are nortorious for collecting water, as well as all kinds of crud. Draining a little off should be a regular ritual, maybe every 6 months or so. I'd have a new rubber gasket for the drain plug. Cheap, and available at any Jaguar parts house, or dealer.

OK, yours may be different, just find the drain on the tank, and I'd bet theres a filter just inside the drain plug. Gotta love these cars, not all the same. Some of the differences come from running out of parts in mid year, and the factory using whatever was available.

My apolizies, I could have sworn I read you had a 87, instead of an 88. Of course there is a difference. My imput would have been OK with the series III, but may not be with your 88. I guess age is taking its toll on my eyesite. Couldn't hurt though, to make sure theres no crud gathering in the tank, blocking the intake lines.
