1994 3.1

Fuel pump only putting out about 20 psi. Limped it home last night

I know it involves dropping the gas tank. Not much fuel in it (3-4 gallons).

How much should it cost at shop? I have two quotes of between $350-400.

May have to do it myself. Any tips/pointers on the procedure?

I have a tech manual that walks you through it

Difficult?

Thanks.
