Fuel pump

[Promod631]

I put in a h&s fuel pin in my truck and wondering if I should turn the fuel up on the ve pump? What gains will I get and what losses?

Have you touch the power screw yet?? If not I would and also bump your timing.

As for gains my 93 with no pin or timing and a 5spd truck I went from bone stock 160hp to 194 at the wheels and for loss I gain in mpg.

I bumped up the timing and just found out about the power screw

[oldestof11]

Is an auto or manual?

[Promod631]

manual or as my son calls it the man trans

[oldestof11]

Fuel pin, power screw to the collar will definitely be felt.

I had a Denny T stage 1, rebuilt stock injectors, K$N air filter, 4" exhaust, 4k gov spring, 60 lbs valve springs, and banjo bolts drilled. All in all, I ran a best of 15.54 and backed it up with runs in the 15.5-15.6 range, all at 84mph. 6200lbs. So 270-290 flywheel hp. It scooted for its size.

On mine its got h&h fuel pin, stock injectors, 4 inch exhaust, and k&n filter. The way I built it is the old cab was rotted out so I redid the whole truck. There are at least parts from 4 different trucks. I estimate it around 4000 pounds and the way it is and it hauls the mail!

[oldestof11]

4000lbs? That sounds light.

[Promod631]

yep. its all gas truck frame body everything except the motor. But I should get it on the scale soon enough.

My '89 regular cab D250 weighed 5300 with me (150) and a tool box (200) in it. It had the short frame.

Jay- did you say you went from 160 to 190 and GAINED MPG ????????
Is that correct ?

[Promod631]

I just turned the pump up at the start of the weekend and its a big improvement over before. It'll be my sons truck and it will be fast enough for him.
