Hey guys. A few months ago I melted a piston in my 302 and decided to build a 351 based engine this time. My original plan was to build a 347, but a 408 isn't much more expensive, so I'm now building a 10.5:1 408w with TFS heads, super victor EFI intake, and a custom cam. The goal for the engine is a 450-500hp N/A fairly reliable street engine. The short block is finished, so as soon as I get the heads and intake done I need to get the truck in the shop and get it ready for the new power plant.

My truck has a 19 gallon single rear tank. It needs a new sending unit anyways, so I would like to replace it with a 33 gallon Bronco tank, sending unit, etc.

My immediate thought was to eliminate the in tank pump and run a single pump on the frame rail like a Walbro GSL392 with a pre pump filter and use the stock filter post pump. My next thought was to sump the tank and do new feed lines all the way to the fuel rails using aftermarket pre and post pump filters, maybe stick to the GSL392 and run the stock return. Another option would be a Walbro pump in tank using stock lines throughout the system.

I wanted everyones opinions and if you've done a Walbro pump in tank, anyone have the part number and what mods are needed to make it work? If you were building this, what route would you take on the fuel system?

 

Bump. I guess I'm going to try posting in the Lightning forum later today and see what some of the gen 1 guys are doing. I've searched quite a bit and found most people are just adding an inline pump on boosted applications with a hobbs switch, but this isn't a boosted app, so that's not gonna do. I will do some more searching on doing the in tank Walbro pump, but yesterday I found quite a few people having fitment issues with them.

 

The folks on NLOC will probably have a better idea how to feed a high HP Ford truck.

 

That's what I was thinking too. I'm going to register over there tonight and see what they think.
