swapping a carbed 302 in my b2 which is currently the 2.9 electric puel pump in the tank. When swapping in the 302, do u run the mechanical pump on it or keep the electric pump and use a pressure reducer? If the electric pump can no longer be used how would I cap off the top of the gas tank where the electric pump goes?

Fuel lines..can i reuse the stock line and attach a fuel block then a flexible hose coming off that? Is it possible to run a long flexible hose or should i keep the hard line?

Let me know how u did yours and whats the easiest way. Sorry for alot of questions!

Use a fuel pump block off plate. Then i would just use your intank electric with a regulator.

I can't think of any PNs off hand but you would need a regulator with a return line or you will kill the high pressure stock pumps.\\Matt

You can use just a tee. One side of the tee to the presure line, one side to the return line and one to the carb. If you run your float bowl empty up in the rpms just restrict the return line a little. If you blow out the needle and seat then you have restricted the return line to much.
If this is on the '88 you can bypass the high pressure pump and just use the primer pump which only makes about 12 psi.
I would just run new line from the fuel tank to the carb, Steel 3/8" line for the pressure line and 5/16" line for the return.

If you have 2 fuel pumps toss the high pressure one and run off the low pressure in tank pump. Use a return regulator back to the tank. If you don't have 2 pumps I would use a different pump completely, a low pressure pump for a carb.

It will depend on the year. I can't tell you for sure, my BII is an 89 but from what I remember starting in 89 is a single in tank fuel pump.

I've used an "elcheapo" 30 gal/hr inline electric on my 89 now for over 5 years. It was enough to feed the 400+hp 3 carbed 331 I had in it at one time. This pump was made by Purolator, I have a similar one now on my 77 Comet also feeding the same 331, but this one's made by Mr. Gasket. Advance Auto Parts stocks this with the performance carb stuff.

Did you ever look at your fuel system. If Your BII came with a 2.9 it should have the primer/pressure pump system. If it had the dual plug (8 plug) 2.3 then it would have a single, in tank pump.
And you don't need to spend big money on a regulator. A tee will work just fine. I've done it many times.

My '88 Ranger has the 2 fuel pump design, one on the drivers side frame rail, under the cab, a little ways back from the fuel filter. The other is in the tank, If you get under there and look, you cannot miss it.

I never though of just using the stock intank pump for a V8 conversion, and eliminating the frame rail pump, that's pretty simplistic.
