Stock fuel pump question

[BIGGSIE]

Will a rewired stock 1G fuel pump be enough to run 550's ?

If you do the SteveTek fuel mod, then probably so. Otherwise, probably not.

Regardless of the fuel lines, I'd say no. Look at the RRE page, the stock pump simply does not flow enough.

I'm not guaranteeing it will not work, but why take the risk?

If you want to find out, buy a fuel pressure gauge.

Exactly.

My rewired 2G pump wouldn't even flow enough for 450's at 100%, and the 1G pump is supposed to be even weaker.

Some people have run 12s on the stock pump... but why risk it?

It costs $90 for a Walbro255 kit that drops right in. Throw on a AFPR (Buschur makes a good one) and rock and roll.
