I have a 1970 Winnebago Motorhome that someone gave me, its in REALLY great codition, but the fuel pump is out. i bought one from napa, but the arm on the fuel pump that sticks in the engine is 4.5" long... The original one off of the motor is only 2" long. ive been calling all over town but everyone stocks this 4" one.. its a 1970 318 engine... any help would be great..

thanks,
chaz.

 

It was a 413, not a 318... the tag was wrong.. fixed the problem. thanks...
