I was hoping to avoid going that route but didn't have that recommendation-

I can see a straight shot to the pump if I take off the inside wheel shroud. but it has plastic rivets holding it in place which would need to be cut and then there's the issue of how to replace it.

Biggest challenge of repairs for me is not to end up with twice as many things to fix as I started with....

I've done one from up top and one from below. Doing it from the top is marginally easier.

Best way is right through the wheelwell, drill out the plastic rivets and remove the plastic inner fender. I then took a sawzall and cut out a little of the steel inner fender (the plastic covers it anyways) and the fuel pump is right there in front of you. It's a lot easier than pullin the starter and reachin up if you don't have access to a lift. You can get the plastic rivets at the parts store for like 40 cents each.

the starter is easy to take off its the easiest part of the whole deal and you can lay under the truck have lots of space to work your going to need it to when you try to get the bolts back in and every thing lined up. be faster then taking off fender and cutting your truck up

Who said anything about taking off the fender? I said the plastic splash shield, and I cut my inner fender BEHIND where the splash shield covers it. I just changed mine a couple months ago so I thought I would offer my .02, If you know the best way to do it Go for it

Thx for the responses. I was gonna head over to napa and see what they had for reattaching that shroud. I can see without removing it that the pump is right there - straight shot. But I can see some of the fender might still be in the way.

Tough choice

I only had to cut out a small piece of the steel inner fender, like 3''x3'' and starting the bolts is a piece of cake through the wheelwell

i just changed mine last week and from what i saw from under with the starter off looked easiest to me. no need to get but hurt, there are 3 different opinions here one from top one from side one from bottom. just check it out from each angle and you decide its straight forward i think the biggest thing is getting the fuel line off and on with out stripping or kinking it. just take your time and don't get frustrated

I didn't have any problem getting the fuel line off and on. Did you get your system bled ? I see you're lookin for an injection pump
