So, I had an idea of simplifying my fuel delivery system by feeding the surge tank passively through a check valve. In my current system, the surge tank is sitting just to the left of the main tank in the back of the vehicle. Currently, it is fed by a low pressure pump and I'm not sure why I'm getting starvation.

 

The simplified idea uses just a check valve and a T in the hose routing. I'd like to get some reactions to see whether this would work well:

 

While on a level surface without cornering, the surge tank fuel level is the same as the main tank:

The surge tank is filled above the level of the main tank by the cornering forces during a right turn:

During a leftt turn, the check valve prevents the surge tank from draining into the main tank:

If the line coming into the surge tank was on the bottom, and the surge tank was tapered to the line, the left/right part wouldn't matter. The other thought that comes to my mind is the check valve has to be reliable with very small pressure changes. Great idea; why have another pump if it is not needed?

Look at the new product - holley hydramat

Other than the price, this looks pretty good - especially the ease of implementing it. Alternatively, I will add that I went through the work of designing, fabricating and installing an in-tank, sump system and have NEVER had any fuel starvation or plumbing or space problems, including one episode where I limped home barely running due to low fuel (bad fuel gauge) and found I had perhaps a cup-full of fuel in the tank. If anyone's interested add a post to this thread and I'll post a link to pictures - or maybe add it to my thread on this list.

Parts alone for my surge system exceeded the Hydramat. But I was a bit nervous abt Hydramat's statement that degradation can occur and that it shd be pulled and checked every 5 years or so for deterioration.

Thx Tom, parts have been purchased and installed. Installation required removal of cage, drivers seat and rear aluminum bulkhead, just to get access, so it was not a simple project. Starvation problem is solved at least.
