TPI in-tank pump

[IndyJimW]

I've got most of the parts to convert my '87 Avanti to TPI but I didn't want to use an external fuel pump. I found what maybe a solution for modifing the fuel tank for an in-tank pump. I need to pull my tank to repair a few items anyway so I'm going to try this pump. How wide is the top of the tank?

For $225.00 it seems like the way to go.

You may wish to reconsider the external pump. They have reduced the noise substantially with resilient mounts on the pump, and running short flex lines before going to hard lines. They also have increased the longevity of the pumps when not in the tank.

I too was a big believer of in tank pumps, as I put one in my 1955 Chevy with TPI and blower.

My friends have been using external pumps successfully for several years. Go to chevytalk.com and do a search on the EFI forum.

Holley supplies this external pump with their EFI kits, and you can find supply houses to purchase it directly with out going through Holley. It is made by Walbro, a reputable manufacturer.

Part number:Walbro GSL392 inline fuel pump

Remember the resilent mounts, and short flex lines. Hard mounting and hard lines will cause noise.
