Re: gas tank inlet extender?
I had this problems for years. When the price of gasoline got up to nearly $5, I was also worried about someone stealing the 56 gallons of gas from the van. So I ordered a replacement door online which is about 9" square and lockable. I marked out the size of hole that I needed with masking tape and paid a body shop to cut the hole. (They just used a Sawzal and I could have done that myself in hindsight.) Problem solved.
