1990 740 GL - Regina - won't accelerate past ~20mph 700

I would check fuel pressure as the previous poster stated. You need 35 psi at idle, and 45 psi with vac line from FPR disconnected. Also, with vac line connected, blip the throttle and fuel pressure should increase from the base 35 psi. If no other obvious problem, collapsed hose, etc., I'd put some money on the fuel pump. Good luck.
