trying to piece together my truck

[clutch810]

so my friend gave me a a gas tank out of a mighty max with an intank fuel pump... it works i dont care. i just want the truck to run. now i have the problem of too much gas being pumped in. any ideas on how to fix this. i need to have it running before school starts in sept, or my parents are going to have it towed out of here. i dont want to lose this great project. its opened my eyes to other cars and trucks besides mustangs and lifted trucks.

ha

thanks

if you have a carburator you need a low pressure pump.

 

I dont know if your truck has a mech or eleltric pump but if its a carbed truck its needs a low pressure of around 3.5 pounds.

 

was the mightey max fuel injected? then its a high pressure pump.

[clutch810]

it was a FI mighty max and it'll shoot a 40foot stream of gas. ha would a regulator work for it?

[groatd]

i would take the might max off and run a stock datsun fuel pump

[clutch810]

is there an intank one?

[banzai510(hainz)]

im not a 620 expert

I guess you can run a regulator and use the return line.

 

I would find a stock pump myself

There's no way a High-pressure, Fuel-injection pump is gonna work. You MIGHT be able to find a low-pressure in-tank pump, but it would need to have the same tank access hole size as the in-tank pumps are almost always a unit. No idea where you would find one. Nissan never made a low-pressure in-tank pump, they were always external even if electric. In-tank pumps became vogue with EFI systems. Possibly a late 80s carbbed pickup, like an Isuzu. But I don't know.
