Need help to design a fuel set-up

Here is what I have - 1974 race car body - 1973 2.0 liter very stock inside - pair of p11 (40) solex carbs - 16 gal fuel cell - and a VERY TIGHT BUDGET -

I think I want 2 cheap fuel pumps on board - flex lines thru the heater duct area - and CHEAP - the fuel cell has a -8 an outlet -

this car is for the www.chumpcar.com racing series of low cost, LONG endurance races -

thanks for y'alls help - live in Savannah but NOT from here !!!!!!!

Facet pump and regulator with a filter of your choice. There are two options.

On this page...

- PUR-40108: Facet Solid State Fuel Pump -6 Fitting 4-6 Max. Pressure

This will have to be adapted from -6 to -8 and the pump... trivial.

But this pump is better for a car with a fuel cell. Again, an adapter to NPT to -8

- PUR-480534

I suggest the following arrangement and the second pump. It'll self prime and you can change the filters without having to drain the cell. The first pump might be fine to. I had that one with a 2.7L motor in this car in an earlier iteration but it was below the stock tank then.

There was never a vapor-lock or priming issue in either design.

Good luck!
