Anyone know the feed and return nipple size on the -SE tank? I think the feed is 7/16 or 1/2" ..

 

1/2

 

Return is 5/16".

 

Cool. trying to figure what I'm going to do for feed and return on my TII swap.. any suggestions.. around 400 RWHP. have a walbro inline already

 

Imho, the best way to do this is modify an SE tank by installing the 2nd gen pickup and internal pump. This eliminates the need for an external pump, and a surge tank if not using the SE tank. I replumbed my supply and return with 3/8" aluminum. Bought a 25' roll at the local speed shop for less than 20 bucks. Took the old lines out and used them as a pattern to bend up the new ones

 

You running a TII? what fuel filter you running?

 

When I did most of the work on the widebody, I set it up for a future TII swap, not there yet unfortunately.

 

For 400HP projected goal,you might wanna up the feed size from what I have,but for my 300HP TII setup,Ive done just fine with the stock size FB feed line,with another stock FB feed line for a return.They are the same size as stock TII lines.
Im also running a stock TII fuel filter.The pump is a SupraTT mounted in the FB tank.

 

3/8" fuel line is big enough to supply 400hp easily. Thats what I'm running on my car, although my engine is only about half that power. I'm overbuilding things now so its easier to up the HP later.

 

I was thinking of running -8 feed from tank to a pre-filter then to walbro then to another last chance filter.. 3/8" for return. I want to feed both fuel rails seperate also

 

I am running 8AN from the tank to the a1000 and 6AN from the pump to the rails.
