I don't think modififying my tank for an in-tank fuel pump would be hard, but I just can't fin any info on how to do it. I need a minimum of 50psi/35gph.

The local radiator shops won't touch it unless its to clean the tank only.

I like the link Stu Cool showed you can use their bolt on FI fuel pump for around 250.


Or for 450 you get a new tank and pump. Nice ,clean ,perfect fit ,and FI fuel pump thats pretty good for a new tank and set-up.

Have you considered moving the tank under the car? That would open up some space inside for storage, stereo or whatever. Just a thought.

Here is a link to description of installing the Tanks Inc pump into another type tank. Maybe that will give you some ideas. Their pumps are plenty strong to do what you want. Mine has no problem with 58 psi needed for an LS1

LOL my 5.0 has a pump in the tank and its the loudest noise on the car when its running Maybe a stock 4 cylinder pump is quiet,/anything that feeds any kind of hp will make lots of noise.
My pump is not that big either and its the first question I always get,whats that buzzing sound
Good luck on quiet in the tank.
My current hotrod has the pump mounted on the frame with rubber isolators and braided hose about 10 inches long on both the input and output and seems to be much more quiet than the in the tank deal and alot more repair friendly,/.....have you ever tried to change a in the tank pump with 8 or 10 gallons of gas still in there? not fun.......
