Hey guys! I want some more info on the subject of fuel pins. There are alot of companys making fuel pins and I wana know who yall thank has the better product!! I found these guys M&H Inc. on ebay(Item# 290402117822) and I am thanking about putting one in my 4bt, but I also have heard good things about Denny T. So what is yalls opinion?

i love my m&h m3 pin. i think the denny t is also a good pin too but very smokey from what i hear. i think the biggest up to the m&h pins is the versatility as where theres 5 levels to choose from and with a denny t theres only one

i think if i had to do it over again i'd get the M4, i'm satisfied with the M3 but under light throttle you can drastically tell when the pin drops. now stompin on it you cant tell the difference tunability is the key with the M&H pins, denny T is virtually the same thing as the M5, smoke tends to be an issue as tltruckparts had said. some have found that too agressive of a pin actually causes more low end problems because of over fueling. prices are that same; varying afew bucks

One thing i learned in college: DON'T!!! stick your fingers where you wouldn't stick Mr. Happy 89' W250, full fuel 1 1/2 turns, smoke screw needs adjustment, M&H M3 fuel pin and timing spacer, 366 spring, air dog 150,3" DP to 4" DP back bully dog exhaust with the front baffle cut out. Soon to be:transmission upgade, turbo and manifold swap, and injectors.

I,too, love my M&H M4 pin. tltruckparts, pretty much nailed the differences, but I would like to add that M&H Inc. is a sponsor on this site and it's good to support those who support us. Plus, M&H is awesome to deal with.

Do i need to get a fuel pin? I already rotated my stock pin and took out my afc srping.

I reckon you do if you want more hp and better performance. It will make a huge improvement. A hundred bucks well spent IMO.

if you get an aftermarket fuel pin i'd go ahead and put your spring back in, if you like the crazy smoke on take off just turn your star wheel down. i wouldnt run with out a spring but that's just me. you dont really NEED another fuel pin but they sure are nice to have. i actually liked my home cut pin, but it was a tad smokey. the M3 pretty much eliminated low end smoke but top end fueling and boost is about the same, i cant really complain other than a power surge when driving lightly. i'd go the M4 route if i could do it over again. but i'm still VERY satisfied with the M3. you really can't beat M&H products

i just didnt know if it would make a difference to get a fuel pin or not since its at the deepest point and i dont have to wait for the fuel to get there, ya know what i mean?

oh it'll make a huge difference... the deepest setting of the stock pin isnt even close to the deepest point of the M&H pins, the stock pin has a gradual steady ramp up, M&H profiles are different and far more aggressive

You can see the difference here.

Denny T Stage II Fuel Pin Review

If I was to do it again I would go with a M&H M3 or M4. My DennyT stage 2 makes great power up top but fuels to hard down low and is hurting my spool up.

i've heard of issues with the bully dog pin being too soft of a steel and the pin wearing a groover into the pin, so any hardened pin would be better at this point. i've got the M3 and i cant really complain, its got a power surge tho, it'd probably be less noticeable possibly eliminated with some AFC tuning, just i havent been able to get around to it.
