Fuel Pump Access

Wow. Thats a HONKER of a hole. I'm going to pull the pump this wknd on my red car and I'll consider cutting an access hole for the future.
From what I recall before, lowering the tank was not hard at all. I dont recall having to do anything with the exhaust the last time. If the whole job takes me more than 1 hour, I'd be surprised.

You have to drop the exhaust as the tank sits above the exhaust pipes.

Fuel Pump fixed

Here is my followup.

I cut the opening leaving one side attached. The mechanic replaced the pump without any problems . It cost $110 for the pump and he charged me $100 for the diagnosis and the install. I gently bent the metal back into place. Then duck taped the seams with Gorilla black tape , then finally sprayed the area with a product similar to Mighty Seal- the as seen on Tv product.

This was the easy way to do it and I think that the mechanic was impressed.

Thanks boys for the info and the hole cutting guidance and courage.

So far she runs fine.

I used this method this morning. I think there are pro's and cons. It was tough to get the proper angle and snake the assembly in place while the tank was still bolted up. I must say it probably saved me about 3 hours of labor. Worth it IMO. Off to Home Depot to get some sheet metal and cover and seal the hole.

Not mentioned when cutting

The fuel lines are directly beneath where you will be cutting . Do not use a sawsall unless you're willing to repair or replace the lines .

Get under the car and look-feel for the pump so you have an idea where you're going then make a cut and fold the metal back until; you can see where you have to go from there.

Be care full and as mentioned here if you can smell gas it can explode. With sparks flying everywhere remember it's the vapor that burns not the liquid.

I have taken a look at a few posts here , unless its a race car , and that is even stretching it , butchering up the car for this is nuts, ....drilling , cutting near a gas tank just to avoid a few hours to remove it properly is completely hillbilly and also dangerous in the future if there is ever an issue with fire under the car , which by the sounds of these actions could very easily encourage .
Get a new good quality pump, pull the tank the right way , clean all connections , test your wires, install and forget about it for another decade .
If you are working on the assumption that it will most likely fail and have to be removed again, then cutting holes in the floor is a band aid to the real problem that needs to be fixed properly.
Way more than .02 worth .

I've done fuel pumps on both of my thunderbirds neither did I pull exhaust off or cut a door what did was remove mounting straps with a floor jack under the tank the lower the jack until the weight was off the jack and on the exhaust then you can pull downward on the passenger front of fuel tank and get enough clearance from there to take the pump out the tricky part is putting the lock ring back on when you can barely see but it can be done I've done it twice took me about an hour and a half start to finish (wasn't timing it just a guesstimate)

Everyone including you are not letting it rest in peace, for the same reason everyone else doesn't , to add their opinion and experience to the topic that others will hopefully benefit from , people read these posts looking for information , so more posts , more information. .. ten people can say jump off a dangerous cliff , all it takes is one to say and explain why its not a good idea ... if someone still wants to jump then they made an informed decision .. not a good one , but they made it .

I was simply answering lateasy's question, which was why this post was awakened.

He wasn't looking for advise on the procedure, people just decided to chime in about it
& not respond to the original question.

He was looking for advice about the procedure , and others were simply responding in the way they deem to be helpful , obviously not the way you want it .
