....for fuel supply that is I know many of you are feeling more confident in running nitrous oxide. But BEWARE I started running out of fuel volume right from launch and well into second gear.
After testing with my mechanical fuel pressure guage, we discovered that I was in big need for more fuel. We actually watched my fuel pressure drop from 40 down to 25 psi. On the juice Not a good thing to stay on the gas, but I felt confident with the PSP program.

So here we are, needing more fuel. And thanks to Sal we now have twin 255 lph fuel pumps.


I think this Fuel pump assembly will handle all that I can throw at her, and then some.

Pictured above is an OEM Lightning fuel pump assembly with larger pumps.

 

so even running a 75 hp shot I may be in need of the twin 255's? I have the NX wet kit. what would be the price on the twin 255's.

 

Jeff,
You will not need an upgrade for anything up to a 100 shot. But I HIGHLY recommend larger pumps with anything over 150+ shot.
Just be sure to change that fuel filter

 

thanks for the info. Since mine is a 99 I should upgrade them anyways. A few people have told me there pumps have died on there 99's?? Is PSP selling the twin 255's?

 

PUT ME IN COACH!!!

 

Sprio:

Are those pumps the same as the ones for the Mustang (I hope, I hope).

Please give us some info on how they went in.

But you might not want to give up those trade secrets if Sal plans on selling them You know, keep it hush, hush

lightning Jeff:

My pump went out when I fisrt got the truck!!

The day I drove it home, the pump(s) went out with only 100 miles on the truck!!

Me and my L had a very rocky start to our relationship

Guys, it's a simple upgrade. Same pumps found on the 87-93 Stangs and newer. In this month's RACE PAGES, I have seen the 255lph pumps as low as 90 bucks

Luckily Sal had a pair left over from his Gen I, and was kind enough to supply me with them. Thanks Sal

 

What about the fuel rails or the other plubling will be adiquate enough to take the extra flow of fuel????

 

I feel the fuel lines will be fine, but I do worry about the fuel rails.

 

Oh man not again....i thought i had everything already!
