Title: 044 pump surge tank mount
Post by: Exidous on October 12, 2019, 10:39:12 PM
I'm going to make a surge tank that fits between the subframe and tank. I want the pump to be mostly submerged but cannot seem to find a seal.

Anyone have ideas?

Worst case I but some cheap crap tank off eBay and make it my own.

I'm using an Integrated Engineering (IE) surge tank which looks to be what a lot of the eBay sellers have knocked off. It has a beefy 1/2" bulkhead and submerges and seals a single or double 044 pump with an oring. I have mine mounted on it's side and still works well. It also uses ORB fittings so no wories about getting thread tape inside the tank. I believe someone did a write up on rx7club installing an IE surge where you're suggesting.

You could always sump your gas tank and mount a external 044 in the same space your talking.  One less pump, I have run mine down to 1/8 and corners hard with no loss in FP.
