I know,there are web forums but the questions and problem I am haveing is not anywhere to be found as far a solution for it.I have googled until I am about google eyed!
I only find other people asking the same questions with little or lame responses.So where can I go to find answers regarding a strong raw fuel odor under the hood of a fuel injected truck when running with no visiable leaks?
I need to get this truck fixed within a month or so for a road trip and this is bothering me.I aint exactly happy about possiably being blown to the moon because of 1 spark and fumes.
Take it to the nearest Chevrolet dealer and bless him with it.
What year is it? Ford seems to use the same EFI across all models.

It could be the vapor canister, purge valve or a leaking vacuum line. What year and is there a trouble code set?
I'm with Ken, these were bad about the vacuum line at the back of the throttle body, they have a elbow there that goes bad. Part is available at the dealers, assuming yours is in the year range I'm thinking of. You will have to feel for it as it can't be seen. KB
Locate Ford Senior Master Technician Jim Twitchell (on the current Ford ads). He may be able to fix it.
Hey,thanks for the hints!
It is a 1991 with 300 Inline 6.
Jack,if it werent for it being my grandfathers that would be a good idea actually.But He was on his death bed with cancer when he had the lawyer come to his hospital room to change the will for me to inherit it.He said I needed a good truck and deserved it for helping him thru his sickness.
I must say,the 300 is a dang good engine,but all these gizmos bolted to it are aggrovateing>it took me to Oklahoma and back so it aint all bad
.Keith,I will check about that.Thanks!

I had a Plain Jane 1990 F150 300 Inline 6.
Darn good Truck. I am lucky enough to have a good Independent Ford mechanic in town to work on it.
Best of Luck.
A fuel system leak should show up on a fuel pressure gauge after shutdown. They should hold pressure for a certain length of time. You can find the specs if you search.
Mack, I was thinking v8 on what I told you, also check the fuel pressure regulator, it will be on the rail, pull off vacuum line and make sure no gas is in the hose. Good luck, KB
My 89 f-150 burned. The cause was determined to be a faulty fuel pressure regulator. Insurance company mentioned they had an issue with them. I am not sure if that was a proven statement but all that was salvaged from mine was the tailgate. It ignited while driving with large flames coming from wheel wells and around hood. I was glad to get out and retrieved no personal items. The truck was less than one year old. Might check the regulator. Ken
Thanks folkes,I will try not to tie up space here.I just needed a fresh heads up.
Esh,I dont want to see flames.I did check for gas at the regulator.all seems well with it.I did by accident find something while checking for the vacuam line elbow.
There is 2 lines going to a charcoal canister.
1 goes to the tanks,1 goes to a solinod valve and vacuam hose.I tried to pull on the vacuam line to check it,and broke the plastic fitting.Well,inside that broken piece was charcoal chunks.I cleaned it out,and repaired the problem with super glue and jb weld.And reinstalled it.It gets good vacaum so I didnt hurt it.But being that Canister Purge solenoid was clogged with charcoal,that coulda been my issue.I also blew thru the line that was going to the tanks to make sure it was clear.
